The AirTAC SC40 Standard Cylinder SC40X35H is a genuine double-acting standard air cylinder with a Ø40mm bore and 35mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X35H is a compact double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 35 mm stroke and a 16 mm diameter piston rod, it suits short-throw clamping, ejecting, and sorting tasks where space is tight.
This variant uses high-temperature Viton (FKM) seals, extending the operating range to 0–150 °C — ideal for autoclaves, drying tunnels, or foundry equipment. The body length A is 142 mm, giving a total extended length of approximately 177 mm. Ports are PT1/4 with an M12x1.25 rod thread, and the adjustable air cushion (21 mm) softens end-of-stroke impact.

Viton seals allow this 40 mm cylinder to operate gates and diverters inside ovens, dryers, or steam tunnels where ambient temperatures reach 150 °C, providing reliable 628 N push force.
Delivers a short, controlled 35 mm stroke for thermal bonding or laminating fixtures. The 16 mm rod and PT1/4 port supply consistent force even as the tooling heats up.
Actuates a dispensing head or needle valve in hot-melt adhesive systems. The 0–150 °C seal rating prevents premature seal failure from conducted heat, maintaining a clean production line.
For applications needing more force, the 50 mm bore SC50 delivers 982 N at 0.5 MPa; for a lighter, more compact actuator, the 32 mm bore SC32 provides 402 N. Always match replacement cylinders on all five key points: bore (40 mm), stroke (35 mm), PT port thread, basic (no accessory) mounting, and the absence of a magnet.
Although the 35 mm stroke is short, ensure the load is guided if any side force is present — even a short rod can bind if the load is not constrained to move axially.
Quick checklist
At 0.7 MPa supply pressure, this 40 mm bore cylinder produces 879 N of push force and 528 N of pull force. 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 an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Only replace another AirTAC SC40 tie-rod cylinder with matching bore, stroke, port, and mounting.
