In order to meet tight schedules and keep overhead down, you need to select chain that will perform and last even under the most rigorous conditions. Rexnord Industries, manufacturer of Rexnord and Link-elt chain for over 00 years, is the leader in the engineered chain industry. Our many years of experience provide unique expertise in material selection, heat treatment and design engineering key factors that add up to superior chain strength and extended wear life. 2 Infeed into one of the many heat treat furnaces used to harden chain components. Note the flame curtain used to protect the furnace atmosphere from the outside environment. What to look for when specifying chain: Wear Resistance chain life is directly affected y the hardness of the wearing components. Quite simply, the harder the parts, the longer the wear life. Rexnord s heat treatment capabilities exceed that of other chain manufacturers. ombine this with the use of choice materials, and it adds up to superior chain that eliminates costly and unexpected downtime. atigue Strength a key factor leading to the durability of our chains is superior fatigue strength. ightly controlled interference fits between the pins and chain sidebars, proper welding and stress relieving, heat treatment and regular testing, and application experience make our chains the number one choice for your particular application. ross-sections of heat treated hain components. he silver surfaces are the result of acid etching and illustrate the deep case depths our chain components have. ustom built induction coils and ancillary equipment have been designed by Rexnord expressly for induction heat treating chain components and sprockets.

5 INROUION Strong, fatigue resistant chain is a function of the press fit of pins and bushings. he plexiglas models below help to illustrate this benefit. ully machined pins offer dimensional accuracy critical in the manufacture of reliable, strong chain. INROUION In an unloaded state, a pin or bushing with a significant press fit will exert compressive stresses around the chain sidebar hole. Low or non-press fit components exert little to none. his photo shows the stress present around a press fit bushing and the lack of compressive stresses around the non- or lowpress fit bushings. Rexnord has invested heavily in N controlled machinery for better lot-to-lot component uniformity. Under load, the stress changes drastically around the low press fit hole but very little around the high press fit hole. Large stress changes reduce the fatigue resistance of chains. or this reason, Rexnord and Link-elt chains use an optimum amount of interference to provide that protective compressive stress! Pre-lubrication and shrink wrapping: Rexnord takes extra steps at the end of manufacturing to protect your chain. ll chains are pre-lubricated and shrink wrapped. his means less corrosion and less break-in wear. It is also better for long-term storage. his photo depicts a fatigue testing machine used by Rexnord to evaluate chain fatigue strengths and guide us in making improvements.

6 SPIL PPLIION IN IG PRORMN LVOR INS* SPIL PPLIIONS IN Rexnord eavy uty levator chains have garnered a reputation as the longest lasting, most reliable chains available today for tough elevating applications. Our chains are the most efficient and reliable to elevate all types of material including clinker, finished cement, fertilizer, and coal. he 900 series chains are the newest addition to this line of chains. With larger components, the 900 series offers 0% greater fatigue strength over their 800 series counterparts. Lightening holes were added to the 900 series to offset the increased weight introduced by larger bushings and pins. No matter which series you choose, you re guaranteed the highest level of heat treatment and manufacturing available in elevator chains today. 800 Series R856 R857 R859 R Series R956 R958 R984 RN SL RINING RING ORY INSLL GRS RSILIN SL Sealed Joint levator hains actory installed grease sealed in, abrasives or corrosives sealed out. n option in these chains and denoted by the SJM prefix.

GRIN NLING INS Rexnord manufactures a wide variety of chains for the grain industry. Welded steel chains are very popular due to the fact that they are easily modified by welding on a variety of attachments. Press fit engineered steel chains with rollers are used in longer, higher load systems. he chains shown are examples of these two chain types. 4 he R series replaces the S, S, RS, X and SX series chains.

7 SPIL PPLIION IN RXNOR N LINK-L NGINR IN PPLIION OR MUSMN RIS, RRIONL LIS, N OR POPL MOVRS rom time to time, chain application questions concerning driving or conveying functions on amusement rides and recreational lifts are brought to Rexnord s attention. oncern arises for the safety and the well being of people utilizing these units should chains prematurely or unexpectedly fail. general review has been made to establish certain rules and recommendations for the selection and application of these rides and conveyances. he following reflects those conclusions:. hain should not be used for any amusement ride or recreational lift application unless there are adequate, functional, and operational safety backup devices to prevent hazardous or unsafe conditions from occurring. 2. hains containing castings or molded parts of any material should not be applied to these applications. his includes pintle, heavy pintle, combination, cast steel, nonmetallic, and similar chains.. ast or welded base chains should not be used in these applications. Welded attachments and other weldments used to augment an engineered steel base chain will be considered on a case by case basis. 4. pplications where a new chain selection is being made will only be considered for customers with qualified engineering expertise. hain selections of any nature should not be made or changed without written approval of the appropriate representatives of an approved Original quipment Manufacturer (OM) of that equipment. his includes replacement chains from any manufacturer including Rexnord. Requests involving like for like replacements will be considered for all customers. Written approval is required for each purpose. 5. hain selections for amusement rides or recreational lift applications should be of the engineered steel types of chain generally covered by NSI standards 29.0, 29.2, and 29.5 after review of all application factors by and approval of the appropriate responsible representative of the original equipment manufacturer of the equipment. 6. hains on these applications should be adequately lubricated and properly maintained at all times. 7. hain reliability is based upon a good press fit of the pins and bushings into the sidebars. herefore, do not grind the chain pins, bushings, or holes in the sidebars in order to assemble the chain as supplied from the factory. 8. lteration of chain destroys the integrity of the press fits of the chain assembly. herefore, do not alter or rebuild any chains for these applications. 9. If a customer applies an engineered chain product without our approval, it is a misapplication and, as such, is not covered by warranty under our standard conditions of sale. Should questions arise covering any of these policies or procedures, please contact your local Rexnord sales representative. SPIL PPLIIONS IN 5

Rexnord began manufacturing drive chain in the late 800 s and has been a leader in drive chain innovation since. oday s chains are a product of over a century of improved product design, testing and application experience. No one else in the industry comes close to our level of expertise. More built-in features for your money ngineered interference fit construction designed to increase chain fatigue life and wear life. State-of-the-art heat treatment of all chain components to assure longer chain life. Rexnord has developed most of its own heat treating equipment in-house for better control and to precisely fit the heat treat needs of drive chain pins and bushings. Pins, bushings and rollers are manufactured to exact tolerances. Sidebars and sidebar holes are punched using the latest punch press technology to give superior fit and finish. Selectively Induction ardened (SI) pins, available in many of our drive chains, afford you unmatched toughness and wear resistance. Ideal for tough, shock loaded applications.

33 RIV INS Wear life is directly affected by the hardness and case depth of the wearing components Ideal replacement for gearing, multiple strand roller chain, and belt drives. Selectively Induction ardened pins (the pin with the crescent-shaped hardened area) are heat treated only on the portion of the pin that experiences wear. he balance of the pin is left in a tough state to withstand shock loading. hain rollers, sidebars and bushings are all heat treated for wear resistance and strength. Pins hardened by Rexnord s advanced induction hardening process feature extremely hard wear surfaces and deep case depths as shown below. Requires less precision and expense than gearing as center distances are more flexible and adjustable. single strand of Rexnord or Link-elt drive chain can frequently replace multiple strand roller chain drives, thus simplifying maintenance. nd unlike multiple strand chains, our drive chains run on simple flame-cut sprockets. asily adjustable. he offset link design allows one link at a time to be taken out or inserted. No special connector links are required. Lower overhung loads than belt drives due to the elimination of pre-tensioning. Rexnord chains run best on Rexnord sprockets lthough our drive chains may be run on commonly available flame cut sprockets, they give better long term performance when matched with our sprockets. Our sprockets are flame cut and induction hardened to give hard, deep case depths. RIV INS Most competitive sprockets have only a fraction of the case depth. Once the case depth is worn through, sprocket wear is rapid and chain interaction is affected, thus causing greater chain stress. I pins (right and bottom) offer very hard and deep case depths around the full circumference of the pin. SI pins (upper left) are hardened only on the load bearing surface so shock can be better absorbed by the back of the pin. Proprietary induction hardening process gives every heat treated sprocket superior case depths and hardness.

Rexnord regularly tests Rexnord and competitive chains. Not all welded steel chains are created equal. What follows is the story of how we make Rexnord Welded Steel chains to be the best - anywhere in the world! Maximizing hain Wear Life hrough Superior eat reatments hain wear life is directly affected by the hardness of the wearing components. Quite simply, the harder the parts, the longer the wear life. Rexnord s heat treatment technology exceeds that of other chain manufacturers. omputer controlled furnaces, and Rexnord designed induction heat treating equipment, produce chain components with the industry s hardest possible wearing surfaces and yet still provide the necessary toughness to resist shock loads. In addition, unique Rexnord process controls provide chains with consistent wear life. his allows users to predict the wear life of their chains, allowing for chain replacement as part of their preventative maintenance programs. In the end, superior chain eliminates costly and unexpected down time. cross section of a selectively induction hardened WX pin the crescent area is super-hardened to dramatically lengthen pin wear life. he balance of the pin material is left in the thru-hardened condition to give the pin excellent toughness. to assure chain toughness and resistance to breakage. his treatment is standard on WX Narrow Mill chains. Most manufacturers of welded chain compromise their design, either sacrificing component hardness or resistance to overloads. Rexnord Wide Mill heat treated chains (W) come standard with thru-hardened rivets, sidebars and barrels. Other manufactures short-change wear life by not hardening the barrels significantly reducing chain wear life. he table below illustrates the importance of superior heat treatment. y using the table, one can predict the increase in wear life by upgrading the heat treatment. s an example, increasing hardness from 5R to 60R could provide up to double the chain life! ll Rexnord Welded Steel chains come standard with premium heat treatments. he photo (top right) shows a cross section of a Selectively Induction ardened (SI) chain pin. his exclusive Rexnord process involves super hardening only the portion of the chain rivet that wears as the chain articulates over the sprockets. he remainder of the rivet is held at thru-hardening levels Importance of eat reatment eat reatment Not ardened hru- ardened Induction ardened ardness R (typ) Relative Wear Life* 2 4 * ry operating conditions 6

If you regularly replace chains due to sidebar wear, you should select SI sidebars. his is a very cost effective way to increase your chain life. Selectively Induction ardened Sliding Surfaces nother key factor in providing maximum chain strength is proper welding, stress relieving, and heat treatment. Improper controls and processes can lead to failures around the weld either from improper weld penetration or by causing high hardness zones that result in brittle failures. Rexnord uses the latest technology in process and quality controls to assure proper weldments. Rexnord welded links are regularly tested during each manufacturing lot to assure our process is in control, producing high quality welds. he photo below shows a welded steel link that has been destructively tested to assure the strength and penetration of the weld. s demonstrated in the photo, the chain material failed first, not the weld. his demonstrates a high quality weld.

Let us put 00 years of experience to work for you! MXIMIZING IN SRNG key factor leading to the durability of Rexnord welded steel chains is superior fatigue strength. Rexnord Narrow Series Welded Steel chains have tightly controlled, interference fits between the pin and chain sidebar hole. his interference fit creates a beneficial residual stress in the sidebar to greatly increase the fatigue life of the chain. he chains have a stepped ( diameter) pin to ease assembly and protect the integrity of the interference fit. ompetitive chains with poorly controlled interference fits (or with clearance fits!) have much lower fatigue strength. Low fatigue strength chains are subject to unexpected chain failures after a chain sees many cycles of loading.

42 WL SL INS RVRS RRL WI MILL RG INS rticulation is etween hain arrel and Sprocket ooth simple and effective solution for an old problem. he Problem: Since their introduction, wide mill welded steel chains were designed to run narrow or closed end forward. his is the direction of travel that the chains on the preceding page run. Running in this direction, an offset sidebar chain will experience scrubbing between the outside of the chain s barrel and the drive sprocket s tooth (igure ). On shorter conveyors, where the chain frequently contacts the sprocket, this scrubbing can cause rapid wear of both the chain and sprocket. his scrubbing may not cause as much chain wear on longer conveyors but it will still cause sprocket wear. igure WL SL INS he Solution: Rexnord engineers realized that if they reversed the barrel of the chain so it could run in the opposite direction, wide or open end forward, the scrubbing action could be eliminated. Instead of the articulation occurring between the outside of the chain barrel and the sprocket tooth it occurs inside the chain joint between the pin and the barrel (igure 2). his arrangement is preferable since both the pin and the barrel of the wide mill chains are heat treated to withstand this type of wear. ow do I Know if I Need Reverse arrel hain?

It is not necessary to remove the prelubricant before welding, however, proper ventilation is mandatory. 2. Weld strength should be sufficiently high to cause failure of the parent metal and not of the weld itself.. Welds should be free of cracks, undercutting, slag, inclusions, and excessive porosity. raters due to stop welding should be located away from corners and edges; most craters contain slight cracks which can initiate failures at high stress areas. 4. Weld beads should be free of pinholes, have uniformly fine surface ripples, and have little or no indication of where a new piece of filler metal was started. 5. Weld edges should indicate complete fusion without overlap or undercut. 6. Welds should be clean, free of spatter, slag, excessive oxides, and arc scars. 7. rcs should be struck on attachments, not on the sidebars. rc scars on sidebars can produce early chain failure. 8. onvex shaped weld beads are preferred. onvex fillet welds are strong and less subject to cracking than concave forms. 9. lectrode selection is very important. n electrode that has been successfully used is 708 (70,000 psi tensile strength, low hydrogen). his rod is for all position use, or.

68 SPROKS SPROK YPS Sprockets can be supplied in various materials and styles, depending upon the application and severity of service requirements. or most engineered chain applications, fabricated steel sprockets are recommended as offering the best combination of performance, availability, and price. abricated steel sprockets can be provided for every chain- tooth combination and are readily available. Sprockets can also be supplied in various cast materials, with or without hardened teeth. he cast sprocket tables present the available patterns for producing cast sprockets. Whatever the types selected, our sprockets are designed for proper chain-sprocket interaction. Rexnord engineers have selected the proper tooth pressure angle, pitch line clearance, bottom diameter and tooth pocket radius for optimum performance and service life. SPROKS SPROK SYLS ast rm ody his type of sprocket is generally used where larger sizes are required. he use of arms reduces weight, facilitates handling, and lowers cost. ast Split (rm or Plate) ody he split body design facilitates mounting and removal from shafts without disturbing bearings or other connected equipment, which greatly reduces installation and downtime. ast Plate ody Plate bodies are generally required for the smaller sizes where the use of arms is impractical, and on larger sizes when the chain pull exceeds the strength of the arm body sprockets. abricated Steel Sprockets abricated steel sprockets are flame cut and manufactured from plain carbon steel. he teeth are flame or induction hardened. Shear Pin sprocket is modified by the addition of shear pin hubs and shear pins. hey are used in applications where jamming or overloading is prevalent. he shear pins are designed to transmit the required torque under normal operating conditions, but to fail when an overload or jam occurs, thus protecting machinery and equipment from damage. Special Sprockets Sprockets can be made of special design, such as flanged-rim (used particularly in the rock products and fertilizer industries). Long-tooth or gappedtooth sprockets can also be made. SGMNL SPROKS N RION WLS an be supplied with either solid or split bodies, and have removable and replaceable sprocket segments or traction wheel rims. Rims are made of specially hardened steel for superior wear resistance. ccurate machining and precisely drilled holes permit sprocket segments to be reversed, thus doubling sprocket life and minimizing downtime. RION WLS Primarily designed for single-strand bucket elevator service, traction wheels can also be used on other type conveyors providing the coefficient of friction is sufficient under normal load to allow the traction wheel to drive the unit. distinct advantage of a traction wheel is that the 66 ast Sprocket rm ody abricated Steel with Lightening oles Shear Pin Sprocket Segmental Sprocket with Split ody ast Split rm ody abricated Steel Split Sprocket rum langed rm ody Sprocket ast Steel Plate ody abricated Steel Plate ody langed Rim Sprocket Segmental raction Wheel with Split ody chain will slip on the wheel in the event of an obstruction or overload, thereby preventing damage to elevator or conveyor components. raction wheels are ideal for service in abrasive environments since there is less scrubbing of the chain on a traction wheel as compared to sprocket.

69 SPROKS SPROKS SLION, SPIIION N ORRING INORMION Number of eeth Sprockets preferably should have no less than 2 teeth, particularly if speeds are high and the chain loads great. Sprockets having less than 2 teeth should be adapted only to slow and medium speeds. he number of teeth and sprocket speed (revolutions per minute) control the amount of impact of the chain seating on the sprocket. Impact is reduced as the number of teeth is increased or as speed is decreased. Likewise the chain pull is reduced as the sprocket size is increased for any one power drive. onsequently, a lighter chain - for greater economy - may often be used. With a greater number of teeth angular motion or friction in the chain joints is reduced. eight of eeth eight of teeth for standard sprockets is generally based on providing a working face that will accept the maximum amount of wear elongation combined with a smooth topping curve. further limitation that takes precedence over the above is that when a sprocket series is capable of being used with chains designed for conveyor/elevator service, the top of the tooth of all standard sprockets having ten or more teeth is designed to be low enough to clear a slat or carrier mounted on the lowest possible K attachment of any chain using sprockets of that series. s a precaution, it is recommended that orders for sprockets specify whether it is necessary for the top of the tooth to clear any slat, bucket or carrier mounted to a chain attachment, or welded to the chain. ore and ub Size he size of the bore and hub are determined by the torque to be transmitted. he hub specification charts included in this catalog provide selections based on a design shear stress of 6000 psi, maximum. Gapped Sprockets Some attachments require gapped sprockets to avoid interference between the sprocket and chain or assembled fittings. Such attachments usually are those wherein the space between sidebars is utilized by the attachment or its fitting. he gap spacing must be a multiple of the particular attachment spacing in the chain, also of the number of teeth on the sprocket. When some teeth must be topped off (that is, omitted) as distinguished from gaps that extend within the root diameter, it will be assumed that topping off the teeth flush with the root diameter will suffice to clear the obstruction. If gaps are required, complete details must accompany the order. RMN abricated steel sprockets are normally supplied with induction hardened teeth. ast sprockets, if hardened, are either induction hardened or cast as chill iron. he catalog cast sprocket tables identify cast sprockets with hardened teeth. Rexnord takes an extra step when heat treating segmental sprockets and tractions wheels to provide the utmost in hardness and case depth. Prior to induction hardening, segmental rims are soaked with carbon in large carburizing pits specifically designed for this purpose. he carburizing process provides deep penetration of carbon into the segment s working surfaces, thereby increasing its hardenability. fter the carburizing process, the segments are taken to induction heat treat area where the segments are enveloped in a large electrical coil, heated to a cherry red, and quickly quenched. his final process produces the hardest, deepest cases available in an engineered sprocket or traction wheel today. he carburizing/induction heat treatment process is standard for most of our segmental sprockets and traction wheels. If you have issues with extreme sprocket wear, this extra step may be the solution. ontact Rexnord to find out if this process is available for your particular sprocket type; not all sizes and styles are available.

Sprockets are to be installed such that all match marks face the same end of the shaft. t the tail end of a multiple strand conveyor, only one sprocket should be fixed (keyed or set screwed) to the shaft. he remainder of the tail sprockets should be allowed to turn freely on the shaft to compensate for differences in strand length that may change over time. Sprockets with ubs entral Order should specify Matched in Sets of wo, Matched in Sets of hree, etc. Sprockets with Unequal ubs If sprockets will be installed with like hubs all facing the same end of the shaft, the order should specify Matched in Line. If sprockets will be assembled with like hubs facing opposite ends of the shaft, the order should specify Matched in Pairs. Sprocket vailability abricated Steel sprockets (split or solid) are readily available and most any sprocket design can be provided. or the quickest possible delivery, Rexnord maintains an inventory of plates and hubs for many commonly used sprockets. ast sprockets with solid hubs are identified in the cast sprocket tables. he sprocket is bored and keyed to order. Split sprockets, sprockets with hub dimensions other than shown, or sprockets with any other nonstandard feature are available but must be cast to order.

86 SPROKS SGMNL RIM SPROKS N RION WLS (ont d.) ast Rims ach traction wheel rim and sprocket rim are induction case-hardened to the highest practical hardness around the entire circumference. he hardness depth is controlled to give the longest wear life, yet leaves the interior tough and ductile perfect qualities for absorbing the impact and shock loads encountered in elevatorconveyor service. Segmental sprocket rims can be reversed (back side of tooth becomes the working face), in order to maximize wear life. Segmental traction wheel rims can be easily installed, no need to even remove the chain in order to replace worn out rims. No burning or cutting is necessary. Our head traction wheel design moves the center of the chain load more closely over the body flange, thus reducing the possibility of hub fatigue problems. Segmental rim traction wheels are split with cuts in the rims that are made diagonally. hese diagonal cuts eliminate the possibility of the segments spalling or chipping at the line of split as a result of chain bushing or barrel line impact. he sides of the segmental traction wheel & sprocket rims are chamfered to allow the chain to enter and leave smoothly without damaging the chain components. ll rims are furnished with high strength UN thread nuts and bolts as standard. hamfered for smooth interaction w/chains Sprocket Rims Sprocket ross Section vailable ast raction Wheel Rims (with olts, Washers and Nuts) Rex -head raction Wheel ross Section raction Wheel Rims Rexnord hain No /2 S02 /2 S02 S0 R Link-elt hain No /2 SS02 /2 SS02 SS0 SS Outside iam.
