3) Max. usable stroke by the lateral load given to the cylinder The area within the solid line shows the relationship between the specified length stroke cylinder and allowable lateral load. The dotted line in the graph shows the case beyond the long stroke limit. i) Judging external lateral load.
Page 8
How to judge Use graph 2 or 3, either of the one applicable to the mounting bracket and bore size of the cylinder, which are used. Check if the stroke of the cylinder model is smaller than the allowable stroke. Ex.) CS2D125-450, mounting angle 0°...
φ125to φ320 4) The relation between cylinder size and max. stroke by the mounting style Table 2 shows max. usable stroke found by calculation on the assumption that the force generated by cylinder itself acts on piston rod or piston rod and tube as buckling force. Therefore the max.

7) Application of 2nd-class pressure vessel regulation due to operating liquid. Every air cylinder intended for use or mounting in Japan, with the gauge pressure of 0.2 MPa or more and the cylinder internal capacity of 0.04 m and more, or with the cylinder inside diameter of 200 mm dia.
3. Mounting・Operation 1) Operating air Compressed air supplied to the cylinder should be filtered using a SMC filter such as series AF and regulated to the specified set pressure using a regulator such as series AR. Warning Use clean air. If compressed air includes chemicals, synthetic oils containing organic solvents, salt or corrosive gases, etc., it can cause damage or malfunction.

3. Securely tighten all stationary parts and connected parts so that they will not become loose. When a cylinder operates with high frequency or a cylinder is installed where there is a lot of vibration, ensure that all parts remain secure. 4....
Caution 1. Operate within the limits of the maximum usable stroke. Refer to the selection procedures for the air cylinder to be used for the maximum usable stroke. 2. Operate the piston within a range such that collision damage will not occur at the end of the stroke.
6. Prevent foreign matter such as cutting chips from entering the cylinder through its supply port. Cutting chips from mounting hole drilling may go into the supply port of a cylinder placed underneath when the cylinder is installed in the job site. 7....
5) Piping Figure 1 is a basic circuit when operating a cylinder with air filter, regulator, solenoid valve and speed controller. Figure 1 Caution 1. Precaution before piping Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove cutting chips, cutting oil and other debris from inside the pipe.
3. Screwing of fitting When screwing the fitting into the port, tighten by the following appropriate torque. 6) Cushion Warning 1. A deceleration circuit or shock absorber, etc., may be required. When a driven object is operated at high speeds or the load is heavy, a cylinder’s cushion will not be sufficient to absorb the shock.
Caution 1. Readjust with the cushion needle. The cushion has been adjusted at the time of shipment. However, before operating the actuator, readjust the cushion needle that is provided on the cover, according to the size of the load and the operating speed. Turn the cushion needle clockwise to restrict the flow, which increases the cushioning effect.
8) Direction control When changing the operating direction of cylinder, choose the most suitable solenoid valve among SMC’s solenoid valve variation. Warning 1. Design circuitry to prevent sudden lurching of driven objects. When a cylinder is driven by an exhaust center type directional control valve or when starting up after residual pressure is exhausted from the circuit, etc., the piston and its driven object will lurch at high speed if pressure is applied to one side of the cylinder because of the absence of...
4. Maintenance 1) Inspection Daily inspection 1. Check the cylinder for smooth operation. 2. Check the cylinder for change of piston speed and cycle time. 3. Check the cylinder for abnormal stroke Regular inspection 1. Check the cylinder mounting bolt and nut for loose. 2.
2) Overhaul When abnormality is found by regular inspection, following portions should be inspected and take corrective action. However, seal kits should be replaced. Table 6. Portion to be inspected, abnormality and corrective action Portion to be Abnormality Corrective action inspected No problem with operation.
3) Disassembly 1. Disassembly should be done in a wide space containing little dust. 2. After removing the cylinder, be sure to protect the end of piping port and rubber hose on the machine side with clean waste to prevent dust from entering.
※The rod cover assembly for φ180 to φ250 are not replaceable. If you want to replace the rod cover assembly, return it to the factory for repair. 4) Assembly 1. Before assembling cylinder, be sure to clean each part to remove dust. 2.
5) Expendable supplies 1.Part No. and seal kits are as follows. CS2- A-PS Tube bore size Table 9. Seal kits Name ø125,140,160 ø180,200 ø250 ø320 Rod seal Piston seal Cylinder tube gasket Cushion seal Scraper Grease pack (10g) Grease pack (20g) Seal kits or individual seal unit supplied from SMC is not packed in sealed up condition.
6) Replacement procedure of seal 1.Dismantling of seal Please refer to “3) Disassembly” for dismantling of rod seal, cushion seal and tube gasket. Since piston seal has a deep groove for sealing, use your hand (not a screw driver) and push from one side of seal and pull it out when it lifts off. 2.
7) Inspection 1. Follow the procedure of the table 11 for inspection after assembly. Table 11. Inspection items Items to be Criteria and test method Criteria Remarks inspected Measure dimensions of main As per drawing, catalog Dimension parts and specifications. 1.Finish of each part should be No defect shall be good.
