The AirTAC Airtac SC32 Standard Cylinder SC32X25H is a genuine double-acting standard air cylinder with a Ø32mm bore and 25mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X25H is a compact double-acting tie-rod cylinder with a 32 mm bore and a short 25 mm stroke, ideal for high-temperature clamping and ejecting tasks. It produces a push force of 402 N at 0.5 MPa and 724 N at the maximum operating pressure of 0.9 MPa, driven by a 12 mm diameter piston rod with an M10x1.25 thread.
This variant is equipped with Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it suitable for foundry, autoclave, or drying equipment where standard seals would degrade. The body length is 140 mm, giving a total extended length of 165 mm, and the adjustable air cushion (21 mm) decelerates the short stroke smoothly.

Viton seals allow this cylinder to operate in ambient temperatures up to 150°C, making it reliable for clamping fixtures in autoclaves, heated presses, and drying ovens.
The 25 mm stroke and 724 N max push force are well-suited for ejecting small plastic or metal parts from molds in high-cycle-rate manufacturing cells.
With its compact 140 mm body and resistance to aggressive thermal cycling, this cylinder is a good fit for test rigs and environmental chamber actuators.
For higher force in the same compact footprint, step up to the 40 mm bore SC40 series, which provides 628 N of push force at 0.5 MPa. The 25 mm stroke is a standard length for the SC32, ensuring fast availability. When replacing an existing unit, match five key points: bore (32 mm), stroke (25 mm), port thread (PT1/8), mounting style (basic), and the Viton seal designation (H) for high-temperature compatibility. Always ensure the load is guided if side forces are present, even on short strokes, to protect the rod bearing.
Quick checklist
At 0.7 MPa operating pressure, the 32 mm bore generates a theoretical push force of 563 N. The pull force on the retract stroke is lower due to the 12 mm rod area, delivering 345 N at 0.5 MPa.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Only replace a like-for-like AirTAC SC32 tie-rod cylinder with matching bore, stroke, and mounting.
