The AirTAC Airtac SC40 Standard Cylinder SC40X315 is a genuine double-acting standard air cylinder with a Ø40mm bore and 315mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X315 is a double-acting tie-rod cylinder delivering 628 N of push force and 528 N of pull force when operated at 0.5 MPa. With a 40 mm bore and a 315 mm stroke, it uses a 16 mm diameter piston rod and PT1/4 ports, making it a compact yet powerful actuator for medium-duty linear tasks.
At its maximum operating pressure of 0.9 MPa, this cylinder generates 1130 N of thrust. The body length A is 142 mm, giving a total extended length of approximately 457 mm. It features an adjustable pneumatic cushion (21 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact and noise.

The 315 mm stroke and 628 N push force at 0.5 MPa suit diverting medium-weight packages on conveyor lines, providing a clean pneumatic actuation for sorting gates.
Delivers consistent 528 N pull force for holding parts during drilling or welding. The adjustable cushion protects the fixture from shock at the end of the 315 mm travel.
Operates sliding doors on small agricultural hoppers or dispensers. The TPU seals handle dusty environments, and the 1130 N max thrust overcomes sticky material buildup.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push force at 0.5 MPa. If a shorter, lighter actuator is acceptable, the 32 mm bore SC32 series offers 402 N at the same pressure. This 315 mm stroke is within the 1200 mm maximum standard stroke for the 40 mm bore.
For strokes of 300 mm or more, always assess side-load conditions. The 16 mm rod on this SC40X315 can bend under significant lateral force when fully extended. If the load is not guided externally, consider adding a guide rail or switching to a guided cylinder to protect the rod bearing and seals from premature wear. To replace an existing unit, match bore, stroke, PT port thread, basic mounting, and the absence of a magnet.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
No, the SC40X315 is not designed for unguided side loads. The 16 mm rod can bend under lateral force at full extension. You must use an external linear guide or replace it with a guided cylinder to absorb side loads and protect the rod seals.
