The AirTAC Airtac SC32 Standard Cylinder SC32X250H is a genuine double-acting standard air cylinder with a Ø32mm bore and 250mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X250H is a compact double-acting pneumatic cylinder with a 32 mm bore and 250 mm stroke, built for high-temperature environments. Its Viton (FKM) seals shift the operating range to 0–150 °C, making it suitable for autoclaves, drying ovens, and foundry equipment where standard polyurethane would degrade.
At 0.5 MPa air pressure, this cylinder delivers 402 N of push force and 345 N on the pull stroke. The 12 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration. The body length A is 140 mm, giving a total extended length of approximately 390 mm.

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 enable reliable operation in autoclave doors, drying ovens, and heat-sealing stations where ambient temperatures reach 150°C.
The 402 N push force at 0.5 MPa is ideal for compact fixtures, jigs, and light assembly presses requiring consistent, repeatable clamping force.
With a 250 mm stroke and adjustable cushion, this cylinder smoothly actuates small diverter gates and sorting flaps on conveyor lines.
For applications needing more force, the 40 mm bore SC40 series provides 628 N push at 0.5 MPa. For lighter, faster cycling, the 32 mm bore is the correct choice. This 250 mm stroke is within the 1000 mm maximum standard stroke for the 32 mm bore.
When replacing an existing cylinder, match five points: 32 mm bore, 250 mm stroke, PT port thread, basic mounting (no accessory bracket), and no magnet. The SC32X250H uses Viton seals—verify the seal material matches your application’s temperature range. For strokes over 300 mm, consider an external guide to protect the rod from side loads.
Quick checklist
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N. The theoretical maximum at 1.0 MPa is 82 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke. It is not dimensionally interchangeable with ISO 15552 profile cylinders. It replaces another AirTAC SC32 cylinder with matching bore, stroke, port, and seal.
