The AirTAC Airtac SC32 Standard Cylinder SC32X275 is a genuine double-acting standard air cylinder with a Ø32mm bore and 275mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X275 is a compact double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure). With a 12 mm piston rod and M10x1.25 rod thread, it is well-suited for light clamping, sorting, and ejector tasks where space is tight.
At 275 mm of stroke, this model operates well within the 1000 mm maximum standard stroke for the 32 mm bore. The adjustable air cushion (21 mm length) decelerates the piston smoothly, reducing end-of-stroke impact. The body length A is 140 mm, giving a total extended length of approximately 415 mm.

The 402 N push force reliably ejects plastic or metal components from injection molds and stamping dies.
Actuates diverter gates on compact conveyor lines handling small packages or electronic components.
Provides consistent clamping pressure for gluing, soldering, or ultrasonic welding fixtures in benchtop automation.
Choose the SC32X275 for light-duty push/pull applications under 400 N. If your load approaches 600 N, step up to the SC40 bore (628 N at 0.5 MPa) to maintain speed and service life. For strokes over 300 mm on this 12 mm rod, evaluate side loads carefully—an external guide or a guided cylinder is recommended to prevent rod bending.
To replace an existing cylinder, match five points: 32 mm bore, 275 mm stroke, PT1/8 port thread, basic (no mounting accessory), and no magnet. This is a genuine AirTAC SC tie-rod cylinder, not an ISO 15552 profile unit.
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 SC32X275 is a double-acting cylinder and does not lock or hold position when air pressure is exhausted or the valve is centered. The piston will drift. For load holding, add a pilot-operated check valve or an external rod brake.
