The AirTAC Airtac SC40 Standard Cylinder SC40X140TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 140mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X140TC is a double-acting pneumatic cylinder with a 40 mm bore and 140 mm stroke, factory-equipped with a centre trunnion (TC) mounting for pivoting applications. It generates 628 N of push force and 528 N of pull force when operated at 0.5 MPa, making it a capable mid-range actuator for moderate linear loads.
This model uses a 16 mm diameter piston rod with an M12x1.25 rod thread and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly near stroke end, reducing impact stress. The TC mount includes the TCM1 bracket (order code F-SC40TC), allowing the cylinder to pivot freely as the rod extends and retracts.

The centre trunnion mount allows the SC40X140TC to pivot, making it ideal for actuating swing-arm diverters on packaging conveyors where the cylinder body must rotate during the stroke.
Delivering 628 N at 0.5 MPa, this cylinder provides consistent clamping force for CNC jigs and welding fixtures, with the adjustable cushion preventing part damage from hard end-of-stroke impacts.
The pivoting TC mount suits agricultural chute or gate controls. The TPU seals and PT ports offer reliable operation in dusty environments with standard filtered air.
Choose the SC40 bore for push forces around 628 N at 0.5 MPa. If your load requires more thrust, step up to the SC50 (982 N at 0.5 MPa); for a lighter, more compact solution, the SC32 provides 402 N. The 140 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
For a direct replacement, match five points: 40 mm bore, 140 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with the F-SC40TC bracket, and the non-magnetic piston (no -S suffix). This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
Quick checklist
At the standard operating pressure of 0.5 MPa, 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. The theoretical maximum at 1.0 MPa is 128 kgf.
No, the SC series is a tie-rod cylinder with a shorter body length (A=142 mm) than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable. It directly replaces another AirTAC SC40 cylinder with the same bore, stroke, PT ports, and TC mount.
