The AirTAC Airtac SC32 Standard Cylinder SC32X285S is a genuine double-acting standard air cylinder with a Ø32mm bore and 285mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X285 is a compact double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 402 N of push force at 0.5 MPa. Its 285 mm stroke and 12 mm diameter piston rod make it a practical choice for light-duty linear actuation tasks where space is limited.
This model features a 21 mm air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact. The total body length A is 140 mm, resulting in an extended length of approximately 425 mm. With a PT1/8 port and M10x1.25 rod thread, it integrates easily into standard pneumatic circuits.

The 402 N push force at 0.5 MPa is well-suited for ejecting lightweight plastic or metal parts from small molds and fixtures in automated assembly cells.
With a 285 mm stroke, this cylinder can actuate small diverter gates on compact conveyor lines, sorting packages or components by extending and retracting a paddle.
The SC32X285 provides clean, oil-free actuation for test tube handling, pipette tip loading, or lid opening mechanisms in laboratory diagnostic equipment.
For applications needing slightly more force, consider stepping up to the SC40 bore which provides 628 N at 0.5 MPa. If your 285 mm stroke involves any side loading, ensure the load is externally guided; the 12 mm rod on this 32 mm bore cylinder is not designed to support bending moments. When replacing an existing cylinder, match all five key points: 32 mm bore, 285 mm stroke, PT1/8 port thread, basic (no bracket) mounting, and no magnet.
Quick checklist
At the standard operating pressure of 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 increases to 724 N.
No, this specific model code does not include the -S magnet option. To use CMSG or DMSG sensors, you would need the SC32X285-S variant, which has a built-in magnet in the piston.
