Table 1 Applicable Cylinder Bore Size Cylinder bore size [] AS22R-- AS22Q-- AS32R-- AS32Q-- AS42R-- AS42Q x Selection of Allowable Jig Weights When the air saving speed controller is used, the jig weight which is ounted to the cylinder should be below the values in the table below. 1 Selection Method If a jig exceeding the allowable jig weight is ounted, the driving speed will change greatly in the iddle of the cylinder stroke, which ay cause a sudden extension. 1 If the load varies during the stroke, such to push out a workpiece, do not use the AS-Q for control on the extension side. This can cause a sudden extension. In this case, use a eter-in control type speed controller. 2 The coeffi cient of friction of the guide should be 0.5 or less. 3 Copare the weight specifi ed based on the cylinder stroke and the allowable lateral load shown in the table and select a weight saller than the actual weight of the jig.

19 AS-R/AS-Q Series Difference between Meter-in and Meter-out Control z Meter-out Control Advantages Supply Easy to adjust the speed. Speed is stabilized for the fluctuation of the load. Vertical control is available. Disadvantages Copressed air on exhaust side is required (causing sudden extension). Regardless of the weight of the load, 100 % of supply is supplied during the oveent of the cylinder. Air which is unnecessary for the load weight is consued. Speed, Stroke, Pressure Exhaust Speed Stroke Caution Make sure that copressed air is present at the exhaust side when starting the operation of the cylinder. Operation without copressed air at the exhaust side causes sudden extension. Start of operation Tie Feature of eter-out control Stroke end x Meter-in Control Advantages Not effected by exhaust condition. Operation starts quickly. Supply depending on the weight load is supplied during the oveent of the cylinder. Only air which is necessary for the load weight is consued. Disadvantages Susceptible for the changes in the load. Susceptible to the external or inertia force. Vertical control is difficult. Adiabatic expansion due to rapid exhaust of air ay for dew in the cylinder. Use of air cushion is difficult. Speed, Stroke, Pressure Start of operation Speed Supply Stroke Tie Exhaust Stroke end Caution Feature of eter-in control Preventive easure against dew foration is necessary when copressed air is supplied. For details, refer to the Precautionary easures against condensation in a pneuatic syste in the Web Catalogue. Sudden extension When copressed air is not present at the exhaust side or is lower than the supply for eter-out circuit, orifice control is unavailable, aking the actuator operate rapidly. There is no sudden extension usually for eter-in circuits. 19

For flow control equipent precautions, refer to the Handling Precautions for SMC Products and the Operation Manual on the SMC website: Design and Selection Warning 1. Check the specifications. The products in this catalogue are designed to be used in copressed air systes (including vacuu) only. If the products are used in an environent where or teperature is out of the specifi ed range, daage and/or alfunction ay result. Do not use under such conditions. (Refer to the specifi cations.) Please contact SMC when using a fluid other than copressed air (including vacuu). We do not guarantee against any daage if the product is used outside of the specifi cation range. 2. The products in this catalogue are not designed for the use as stop valve with zero air leakage. A certain aount of leakage is allowed in the product s specifi - cations. Tightening the needle to reduce leakage to zero ay result in equipent daage. 3. Do not disasseble the product or ake any odifications, including additional achining. It ay cause huan injury and/or an accident. 4. The flow rate characteristics for each product are representative values. The fl ow rate characteristics are characteristics of each individual product. Actual values ay differ depending on the piping, circuitry, conditions, etc. 5. Sonic conductance (C) and critical ratio (b) values for products are representative values. The speed controller s controlled flow values are with the needle fully open and free flow with the needle fully closed. 6. Check if PTFE can be used in application. PTFE powder (Polytetrafl uoroethylene resin) is included in the seal aterial for piping taper thread of ale thread type. Confi r that the use of it will not cause any adverse effect on the syste. Please contact SMC if the Safety Data Sheet (SDS) is required. Mounting Warning 1. Operation Manual Install the products and operate the only after reading the Operation Manual carefully and understanding its contents. Also, keep the Operation Manual where it can be referred to as necessary. 2. Ensure sufficient space for aintenance activities. When installing the products, allow access for aintenance. 3. Tighten threads with the proper tightening torque. When installing the products, follow the listed proper torque. Warning Locked Marker for fully closed position Fully closed Marker for fully open position Fully open Mounting 4. After pushing the knob down to lock, confir that it is locked. It should not be possible to rotate the knob to the right or to the left. If the knob is pulled with force, it ay break. Do not pull the knob with excessive force. Unlocked 5. Check the rotation angle of the knob. Rotation angle is 270 degrees. The knob cannot be rotated ore than this. Excessive rotation will cause daage to the product. Check the rotation angle before using the product. Knob operation range 0 (Fully closed) (Fully open) Adjustent can be ade every 45 degrees. 6. Do not use tools such as pliers to rotate the knob. It can cause idle rotation of the knob or daage. 7. Verify the air flow direction. Mounting backward is dangerous, because the speed adjustent needle will not work and the actuator ay lurch suddenly. 8. Adjust the speed by opening the needle slowly fro the fully closed state. Loose needle valves ay cause unexpected sudden actuator lurching. When a needle valve is turned clockwise, it is closed and actuator speed decreases. When a needle valve is turned counterclockwise, it is open and actuator speed increases. 9. Do not apply excessive force or shock to the body or fittings with an ipact tool. It can cause daage or air leakage. 10. Refer to the fittings & tubing precautions in the Best Pneuatics catalogue for handling One-touch fittings. 20

Exaple) When the product ounted on the head side is adjusted: AS-Q Product Atospheric When the product ounted on the rod side is adjusted: Caution Piping 1. Refer to the fittings & tubing precautions in the Best Pneuatics catalogue for handling One-touch fittings. 2. Preparation before piping Before piping is connected, it should be thoroughly blown out with air (fl ushing) or washed to reove chips, cutting oil and other debris fro inside the pipe. 3. Winding of sealant tape When screwing together pipes and fi ttings, etc., be certain that chips fro the pipe threads and sealing aterial do not get inside the pipe. Also, when the sealant tape is used, leave approx. 1 thread ridge exposed at the end of the threads. Winding direction Atospheric Product AS-R AS-Q Pressure Expose approx. 1 thread ridge. Sealant tape Moveent Adjust the product when the cylinder operates in the direction of the arrow or copletes the operation. Piping Threads with Sealant Caution 1. If the fitting is tightened with excessive torque, a large aount of sealant will seep out. Reove the excess sealant. 2. Insufficient tightening ay loosen the threads, or cause air leakage. 3. Reuse 1) Norally, fi ttings with a sealant can be reused up to 2 to 3 ties. 2) To prevent air leakage through the sealant, reove any loose sealant stuck to the fitting by blowing air over the threaded portion. 3) If the sealant no longer provides effective sealing, wind sealing tape over the sealant before reusing. Do not use the sealant in any for other than a tape type. 4) Norally, G thread (face seal) can be reused up to 6 to 10 ties. Seals cannot be replaced. 4. Once the fitting has been tightened, backing it out to its original position often causes the sealant to becoe defective. Air leakage will occur. 5. Use R external threads with Rc internal threads and NPT external threads with NPT internal threads. 22
