Page 6: Precautions On Model Selection
1-4．Precautions on model selection C a u t i o n ①Choose the optimum bore size based on the applications operating conditions such as load, travel distance (stroke), stroke time, mounting orientation, operating pressure, etc. ②Attention should be taken so that the operating speed does not exceed the max. speed for the cylinder. Adjust the maximum speed of cylinder using the speed controller so that the load travels the stroke slower than the stroke time, ③Stroke time means the time taken for the load moving from the start of the stroke to the end without intermediate stop. - Page 7 Selection graph - 6 -...
- Page 8 Step 3 Make sure that the allowable kinetic energy of cylinder is not exceeded. Based on the Graph 8, confirm that the allowable kinetic energy of the cylinder is not exceeded at the load weight and maximum speed selected in Step 1 and 2. 1) Air cushion is effective 2) Air cushion is not utilized Graph 8.
- Page 9 Step 4 Lateral load applied to the rod end shall not exceed the limit of allowable load. Make sure that lateral load applied to the piston rod end does not exceed the allowable load limit referring to the Graph 9. Bushing (bearing) Chart 9 Allowable lateral load applied to rod end The bold solid lines in Chart 9 show the allowable lateral load on the cylinder for a certain stroke length.

2. Installation and Handling 2-1. Air supply ① The air supplied to the cylinder should be filtered by SMC AF series air filter and regulated to the specified set pressure by SMC AR series regulator. W a r n i n g ・Type of fluids Please contact SMC when using the product in applications other than with compressed air. -
Page 11: Design
2-2. Design The compatibility of the product is the responsibility of the person who designs the equipment or decides its specifications. W a r n i n g ・There is a possibility of dangerous sudden action by cylinders if force is changed due to twisting of sliding parts of machinery. -
Page 12: Mounting
2-3. Mounting The foot mounting cylinder has a hole in the foot to drive a pin into for accurate positioning and fixing. C a u t i o n ・Do not apply excessive lateral load to the piston rod. Please refer to Chart 9. Allowable lateral load applied to rod end. (Page 8) W a r n i n g ・Make sure to release the lock before connecting the load to the rod end. -
Page 13: Operating Environment
・There is a vent hole on the element. If the ventilation is not adequate, there will be locking/ unlocking delay or operation failure. Install the cylinder so that the element is not covered. Keep 10mm or more away from the wall. Element Fig. -
Page 14: Speed Control
2-5. Speed control 1) When the piston speed is adjusted, install SMC AS series speed controller near the air supply port to adjust to the specified speed. 2) Use speed controllers to adjust the speed. There are two types of speed controllers for adjusting the speed: one is to regulate the supplied air into the cylinder (meter-in control), and another is to regulate the exhausted air from the cylinder (meter-out control). -
Page 15: Pneumatic Circuit
Design the machinery to avoid such dangers. 2-8. Pneumatic circuit W a r n i n g ① Use the pneumatic circuit which applies balance pressure to the both sides of the piston when locking. To prevent sudden extension when operation restarts or lock is released, control the cylinder to make balancing pressure applied to both sides of the piston so that the force generated in the operating direction of the piston due to load can be counteracted. -

Page 17: How To Use
3. How to Use 3-1. Usage ① For intermediate stop, take stopping accuracy and overrun into consideration. As this is a mechanical lock, there will be a slight time difference for the stop signal and delay of the cylinder. The cylinder stroke during the delay is called overrun. The range between maximum and minimum overrun is referred to as overrun. -

3-2. Lock release mechanism Operation principle for unlocking mechanism. Hexagon wrench Unlocking port (Exhaust air pressure) Spring Release bolt Locked Manually unlocked Fig.6 Operation principle of locking mechanism (Fig. 6 is for reference for the operation principle. (Different from the actual structure)) C a u t i o n The manual lock is released as default. - Page 19 W a r n i n g (1) Do not operate the release bolt until safety is confirmed. Do not twist a) If only one side of the cylinder is pressurized during unlocking, the moving part of the cylinder may extend suddenly which can be very dangerous b) Carefully confirm that personnel are not within the moving range of the load and there is no danger, even if the load moves suddenly.
