The AirTAC Airtac SC40 Standard Cylinder SC40X325H is a genuine double-acting standard air cylinder with a Ø40mm bore and 325mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X325H is a double-acting tie-rod cylinder with a 40 mm bore and 325 mm stroke, factory-equipped with Viton (FKM) seals for reliable operation in high-temperature environments from 0 to +150 °C. It delivers a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa, driven by a 16 mm diameter piston rod with M12x1.25 male threads.
With a compact body length of 142 mm and a 21 mm adjustable air cushion at each end, this SC series cylinder decelerates the piston smoothly to reduce end-of-stroke impact. The PT1/4 port and standard tie-rod construction make it a direct replacement for existing AirTAC SC40 installations requiring elevated thermal resistance.

Viton seals enable this 40 mm bore cylinder to operate continuously in ovens, autoclaves, or near heat sources up to 150 °C, where standard seals would degrade.
With 628 N of force at 0.5 MPa and a 325 mm stroke, it reliably diverts hot parts or materials on conveyor lines without risk of seal failure from ambient heat.
The adjustable cushioning and 1130 N maximum thrust at 0.9 MPa make it suitable for ejector mechanisms in heated injection or compression molding tools.
For applications needing more force at the same pressure, stepping up to the 50 mm bore SC50 series provides 982 N of push force at 0.5 MPa. If a shorter overall length is required, the 40 mm bore can be stepped down to the 32 mm bore SC32, which offers 402 N at 0.5 MPa.
At a 325 mm stroke, ensure the load is guided and side forces are minimized to prevent bending stress on the 16 mm rod. For exact drop-in replacement, match five key specifications: 40 mm bore, 325 mm stroke, PT1/4 port thread, basic mounting (no factory brackets), and the high-temperature Viton seal variant (-S magnet is not present on this model).
Quick checklist
At 0.7 MPa operating pressure, the theoretical push force is 879 N and the pull force on the retract stroke is 528 N, based on the 40 mm bore and 16 mm rod diameter.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (142 mm body for the 40 bore) than a comparable ISO 15552 profile cylinder, so mounting dimensions are not interchangeable. It is a direct match only for another AirTAC SC40 tie-rod cylinder with the same stroke, port thread, and Viton seal option.
