The AirTAC Airtac SC32 Standard Cylinder SC32X125SH 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 SC32X125SH is a compact double-acting pneumatic cylinder delivering 402 N of push force at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure). Its 12 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for the 125 mm stroke, making it a solid choice for light-duty clamping and sorting tasks.
This variant includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling rod-position feedback without external brackets. The H suffix specifies Viton (FKM) seals, shifting the operating temperature range to 0–150 °C for use in hot environments where standard TPU seals would degrade.

The Viton seals allow this cylinder to reliably eject small plastic or metal parts from heated molds or ovens, where ambient temperatures up to 150°C would cause standard seals to fail.
Actuates a small diverter gate on a conveyor line carrying hot materials. The built-in magnet with sensors confirms the gate's open/closed position to the PLC for safe material routing.
Used in a sterilizing autoclave to clamp a small fixture. The FKM seals withstand the repeated high-temperature steam cycles, while the magnetic piston allows for end-of-stroke sensing.
For applications needing more force, stepping up to the 40 mm bore SC40 series provides 628 N of push at 0.5 MPa. If your load is lighter and you need a smaller footprint, the 32 mm bore is the right choice. For this 125 mm stroke, the rod is well-supported within the standard stroke range, but always avoid direct side loads on the rod.
When replacing this cylinder, match five key points: 32 mm bore, 125 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting style. The SC32 is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.7 MPa operating pressure, the theoretical push force is 563 N, and the pull force is 483 N. The maximum push force at the 0.9 MPa operating limit is 724 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than a comparable ISO 15552 profile cylinder. It is a direct replacement only for another AirTAC SC32 tie-rod cylinder with matching bore, stroke, magnet, and port thread.
