The AirTAC Airtac SC32 Standard Cylinder SC32X20H is a genuine double-acting standard air cylinder with a Ø32mm bore and 20mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X20H is a compact double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa, making it suitable for light-duty pneumatic tasks in high-temperature environments. Its 12 mm diameter piston rod and 21 mm air cushion provide reliable deceleration at the end of each stroke.
Equipped with Viton (FKM) seals, this model operates reliably from 0 to +150 °C, ideal for foundries, drying ovens, or autoclave peripherals where standard seals would degrade. The short 20 mm stroke suits clamping, ejecting, or sorting mechanisms in tight spaces.

With Viton seals rated to 150 °C, this cylinder handles part clamping in heated presses, soldering fixtures, or composite curing molds where ambient heat would damage standard seals.
Operates reliably through repeated sterilization cycles. The 20 mm stroke is ideal for small door interlocks, valve actuation, or sample handling inside medical autoclaves.
Suitable for ejecting hot-formed small parts or diverting products on a mini conveyor near ovens. The short stroke provides fast cycle times in high-temperature zones.
Choose the SC32X20H for high-temperature applications up to 150 °C where a 32 mm bore provides sufficient force. If your load requires more thrust, step up to the SC40 series, which offers 628 N at 0.5 MPa. For side-loaded or guided applications, consider an external linear guide; the 12 mm rod is not designed to absorb significant bending moments. When replacing an existing cylinder, match bore, stroke, PT port thread, and ensure the seal material is Viton for thermal compatibility.
Quick checklist
At 0.5 MPa (5 bar), 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.
This specific model (SC32X20H) does not include the -S magnet option, so standard tie-rod mounted sensors cannot be used directly. If you need position sensing, order the SC32X20SH variant which includes a built-in magnet compatible with CMSG/DMSG sensors.
