The AirTAC Airtac SC32 Standard Cylinder SC32X40H is a genuine double-acting standard air cylinder with a Ø32mm bore and 40mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X40H is a compact double-acting tie-rod cylinder equipped with Viton (FKM) seals, extending its operating temperature range to 0–150 °C for hot or aggressive environments. With a 32 mm bore and 40 mm stroke, it produces 402 N of push force at 0.5 MPa and up to 724 N at the maximum operating pressure of 0.9 MPa.
This model features a 12 mm diameter piston rod with an M10x1.25 knuckle thread and PT1/8 port connections. The adjustable air cushion at each end provides a 21 mm deceleration zone, and the total body length A is 140 mm. It is a genuine AirTAC SC-series cylinder built for reliable high-temperature actuation.

Viton seals allow this cylinder to operate reliably in ovens, autoclaves, and foundry equipment where ambient temperatures reach up to 150 °C, unlike standard TPU-sealed cylinders.
Delivers 724 N of clamping force at 0.9 MPa in a short 40 mm stroke, perfect for ejecting small hot parts from molds or holding workpieces during thermal processing.
The FKM seal material resists aggressive cleaning agents and steam sterilization cycles, making it suitable for pharmaceutical or food-processing equipment that undergoes regular washdowns.
Choose the SC32X40H when your application requires a compact actuator capable of withstanding elevated temperatures up to 150 °C. If you need more force, stepping up to the 40 mm bore provides 628 N at 0.5 MPa, while the 32 mm bore is ideal for lighter, space-constrained tasks. For a direct replacement, match the 32 mm bore, 40 mm stroke, PT1/8 port thread, and ensure the replacement also carries the -H Viton seal designation. The built-in magnet option (-S) is not present on this model, so position sensing requires external limit switches rather than barrel-mounted sensors.
Quick checklist
At the standard operating pressure of 0.5 MPa, the push force is 402 N and the pull force is 345 N. The maximum push force at 0.9 MPa is 724 N. The theoretical maximum force at 1.0 MPa is 82 kgf.
No. The SC32X40H is a double-acting cylinder and does not hold its position when air pressure is exhausted or the directional valve is centered. The piston will drift or drop. If load holding is required, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
