The AirTAC Airtac SC40 Standard Cylinder SC40X95H is a genuine double-acting standard air cylinder with a Ø40mm bore and 95mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X95H is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, factory-equipped with Viton (FKM) seals for reliable operation in high-temperature environments up to 150°C. With a 40 mm bore and 95 mm stroke, it produces a push force of 628 N at 0.5 MPa and reaches 1130 N at the maximum operating pressure of 0.9 MPa, driven by a 16 mm diameter piston rod.
This model uses a PT1/4 port and an M12x1.25 rod thread, with a 21 mm adjustable air cushion at each end to decelerate the piston smoothly. The body length A is 142 mm, giving a total extended length of approximately 237 mm. As a genuine AirTAC component, it is built for demanding thermal cycling applications where standard seals would degrade.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
With Viton seals rated for 0–150°C, this cylinder is ideal for actuators near ovens, autoclaves, or heated presses where standard TPU seals would fail.
Delivers 1130 N of force at 0.9 MPa for consistent part clamping in hot-forming dies or welding fixtures, maintaining seal integrity under sustained heat.
Suited for throttle actuators or exhaust diverters in engine test cells, where ambient temperatures regularly exceed 70°C and require FKM seal reliability.
Choose the SC40 bore when your application needs between 528 N (pull) and 628 N (push) of force at standard 0.5 MPa shop air. If you require more force, stepping up to the SC50 bore provides 982 N push at the same pressure. For lighter, more compact requirements, the SC32 delivers 402 N push. This 95 mm stroke is within the standard range for the 40 mm bore, which supports strokes up to 1200 mm.
When replacing an existing cylinder, match five key points: 40 mm bore, 95 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and the absence of a built-in magnet. The Viton seal variant is specifically for high-temperature duty; ensure the replacement also carries the 'H' suffix to maintain the 0–150°C operating range.
Quick checklist
At 0.7 MPa supply pressure, the SC40 bore generates 879 N of push force and 739 N of pull force (calculated from the 528 N pull at 0.5 MPa ratio). The maximum operating push force at 0.9 MPa is 1130 N.
This SC40X95H does not have the '-S' magnet option, so it lacks a piston magnet. To use CMSG/DMSG sensors for position feedback, order the SC40X95HS variant instead. The Viton seals remain compatible with sensor-ready configurations.
