The AirTAC SC40 Standard Cylinder SC40X30H is a genuine double-acting standard air cylinder with a Ø40mm bore and 30mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X30H is a compact-stroke double-acting cylinder built for high-temperature environments, with Viton (FKM) seals extending the operating range to 0–150 °C. At 0.5 MPa it provides 628 N push and 528 N pull, driven by a 16 mm diameter piston rod with M12x1.25 male threads.
With a 30 mm stroke and a body length A of just 142 mm, this model fits tight automation spaces where heat resistance is critical. The adjustable air cushion (21 mm length) decelerates the end-of-stroke mass smoothly, and the PT1/4 ports connect to standard pneumatic plumbing.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Viton seals allow direct mounting near ovens, autoclaves, or heated platens where ambient temperatures reach 150 °C, eliminating the need for thermal standoffs.
The 30 mm short stroke and 628 N push force suit clamping specimens in environmental test chambers that cycle between cold and hot extremes.
Withstands the radiant heat from mould tools, providing reliable short-stroke ejection or gate-cutting force without seal degradation.
Choose the SC40X30H when ambient or media temperatures exceed the standard 70 °C limit—the Viton seals maintain full performance up to 150 °C. If your force requirement is lower, the SC32 bore offers 402 N push at 0.5 MPa; for more force, step up to the SC50 at 982 N push.
For replacement, match five points: bore (40 mm), stroke (30 mm), PT port thread, basic mounting, and the -H high-temperature seal variant. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.7 MPa supply pressure the cylinder produces 879 N extending (push) and 528 N retracting (pull). The maximum operating force at 0.9 MPa is 1130 N push.
No. The SC40X30H model code does not include the -S magnet suffix, so the piston does not carry a magnetic ring. To use CMSG/DMSG sensors, order the SC40X30SH variant instead.
