The AirTAC Airtac SC32 Standard Cylinder SC32X125H is a genuine double-acting standard air cylinder with a Ø32mm bore and 125mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X125H is a double-acting tie-rod cylinder with a 32 mm bore and 125 mm stroke, factory-equipped with high-temperature Viton (FKM) seals. This shifts the operating temperature range to 0–150 °C, making it suitable for autoclaves, drying tunnels, and hot-work environments where standard TPU seals would degrade.
At 0.5 MPa it provides 402 N push and 345 N pull, with a maximum push of 724 N at 0.9 MPa. The 12 mm diameter piston rod features an M10x1.25 knuckle thread, and the adjustable air cushion (21 mm length) decelerates the piston smoothly at stroke end. The body length A is 140 mm, giving a total extended length of approximately 265 mm.

Viton seals enable reliable double-acting actuation in autoclave doors, drying ovens, and steam-assisted processes up to 150 °C, where standard seals would fail prematurely.
With 402 N of push force at 0.5 MPa, this 32 mm bore cylinder fits tight fixtures for light-duty clamping, small-part ejection, and pick-and-place tooling on assembly lines.
The clean, oil-compatible Viton seals and filtered-air operation suit lab automation, tensile testers, and environmental chambers requiring consistent force and thermal resilience.
For applications needing more force, step up to the SC40 series which delivers 628 N push at 0.5 MPa from a 40 mm bore. If a lower force is acceptable, this 32 mm bore is the smallest standard SC frame. The 125 mm stroke is well within the 1000 mm maximum standard stroke for bore 32.
When replacing an existing cylinder, match five points: 32 mm bore, 125 mm stroke, PT port thread, basic (no bracket) mounting, and the -H Viton seal designation. This model does not include a built-in magnet; if magnetic piston sensing is required, specify the -S suffix (e.g. SC32X125SH).
Quick checklist
At 0.5 MPa the cylinder produces 402 N extending and 345 N retracting. 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 profile cylinder, so mounting dimensions and body length A (140 mm) differ. It is a direct replacement only for another AirTAC SC32 tie-rod cylinder with matching bore, stroke, PT ports, basic mount, and Viton seals.
