The AirTAC Airtac SC32 Standard Cylinder SC32X70H is a genuine double-acting standard air cylinder with a Ø32mm bore and 70mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X70H is a double-acting pneumatic cylinder with a 32 mm bore and 70 mm stroke, built with high-temperature Viton (FKM) seals for reliable operation in environments from 0 to +150 °C. It delivers a push force of 402 N at 0.5 MPa and up to 724 N at the maximum operating pressure of 0.9 MPa, making it a compact yet capable actuator for hot-zone automation.
This tie-rod cylinder uses a 12 mm diameter piston rod with an M10x1.25 rod thread and PT1/8 ports. The adjustable air cushion, with a 21 mm cushion length, decelerates the piston smoothly at end-of-stroke to reduce impact. With a body length A of 140 mm, the total extended length is approximately 210 mm, fitting neatly into space-constrained thermal applications.

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 allow this cylinder to operate in autoclaves, ovens, or near heated platens where standard seals would fail, reliably actuating gates or clamps at temperatures up to 150 °C.
Suitable for steam-sterilized environments in pharmaceutical or food processing machinery, where the 724 N push force at 0.9 MPa cycles valves or diverters through high-temperature washdown.
Actuates small mould slides or cooling air dampers near furnaces. The 12 mm rod and compact 210 mm extended length fit tight spaces while resisting ambient heat.
Choose the SC32X70H when your application requires a 32 mm bore cylinder that can withstand elevated temperatures up to 150 °C. If you need more force, the next step up is the SC40 series, which provides 628 N of push force at 0.5 MPa. For a drop-in replacement, match the bore, 70 mm stroke, PT port thread, and ensure the replacement cylinder also uses Viton seals for high-temperature compatibility. This model does not include a built-in magnet, so if sensor-based position feedback is needed, consider the -S variant or use external limit switches.
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 force at 1.0 MPa is 82 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is shorter than an equivalent ISO 15552 cylinder, so it is not dimensionally interchangeable. It can only directly replace another AirTAC SC32 tie-rod cylinder with the same bore, stroke, and port thread.
