S onveyor Hollow earing in This chain has all the bearing pin hollow. The hollow bearing type chain gives easy facility for fixing attachments to outer links by bolting through the hollow bearing pins. Spigot pins may be assembled through hollow bearing pin and are secured by a nut or spring washer. t is suitable for use in normal conditions. ased on the strength of the chain, minimum and maximum pitches are available. The minimum pitch is governed by the need for adequate wheel tooth strength and the maximum pitch being decided by link and general chain rigidity. n addition to the standard chain and rollers, these chains are available in stainless steel, zinc plated, flange roller, nylon roller etc. Standard itches : 1.5", ",.5", 3", ", ", " and ".

S ONVEYO HN SOL ENG N HN The solid bearing pin chain has the same gearing dimensions Le pitch, inside width and roller diameter as the equivalent hollow bearing pin chain. t has higher breaking load rating and is more robust and recommended for arduous conditions. ny type of attachment can be fixed as per the requirements. ased on the strength of the chain, minimum and maximum pitches are available. The minimum pitch is governed by the need for adequate wheel tooth strength and the maximum pitch being decided by link and general chain rigidity. eep Link has side link with a greater depth than the normal chain link.

S ONVEYO SOKETS Our standard sprockets are manufactured from steel having one side boss. Sprocket with largest possible diameter should be used in order to reduce strain a and to minimize the polygonal effect. For majority of conveyor applications, experience shows that Toothrepresents a reasonable minimum size for sprockets. Sprocket below Tooth should be avoided if space is no restriction Sprockets with both side boss, split type, segmental sprockets etc are available on request. Stainless steel sprockets are also available for use in high temperature or corrosive conditions.

For operation at temperature from 00 to, stainless steel is used. For temperature from to 00, heat resisting stainless steel must be used. 5) To ensure maximum efficiency of the conveyor, wheel with largest possible diameter should be used in order to reduce strain on the chain joints and to minimize the polygonal effect. For general purpose conveyor teeth sprocket should be used, and for bucket elevator 1 teeth sprocket should be used. ) For scraper conveyor technical data please consult us. 7) To calculate the actual working force, consideration should be given to loading factor (1 to 1.5) work area factor (1 to 1.), service factor (1 to 1.), speed factor (0. to 1.), and uneven load sharing factor when or more chains are used. ) The working force for each chain (F,) is the total force (F) divide by the number of chain rows (N) F 1 F N 9) To obtain optimum performance and higher chain life, regular and effective lubrication of the chain bearing surfaces is essential. 9
