The AirTAC Airtac SC32 Standard Cylinder SC32X325 is a genuine double-acting standard air cylinder with a Ø32mm bore and 325mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X325 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 32 mm bore with a 325 mm stroke. At 0.5 MPa it generates 402 N pushing force and 345 N pulling force, making it a compact workhorse for light-to-medium automation tasks.
This model features a 12 mm diameter piston rod with M10x1.25 threads and a 21 mm adjustable air cushion at each end for smooth deceleration. The body length A is 140 mm, giving a total extended length of approximately 465 mm. Operating pressure spans 0.15–1.0 MPa with a speed range of 30–800 mm/s.

The 325 mm stroke pushes lightweight items off a conveyor line. The 402 N force at 0.5 MPa is ample for plastic or cardboard packaging divert gates.
Lifts and lowers a small gripper or vacuum cup over a 325 mm vertical travel. The adjustable cushion prevents jarring stops that could disturb delicate parts.
Applies a controlled push or pull in a lab test rig. The 345 N pull force at 0.5 MPa and smooth cushioning suit repetitive cycling on a life-cycle tester.
For applications needing more force, the 40 mm bore SC40 delivers 628 N push at 0.5 MPa—a 56% increase. If space is tighter and the load is lighter, a 25 mm stroke variant of the SC32 may fit. At 325 mm stroke, the 12 mm rod is relatively slender; avoid direct side loads or use an external guide rail to prevent rod bending and premature bearing wear.
To replace an existing cylinder, match five points: 32 mm bore, 325 mm stroke, PT1/8 port thread, basic (no bracket) mounting, and no magnet. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, push force reaches 724 N. The theoretical maximum at 1.0 MPa is 82 kgf.
No. The SC32X325 is a double-acting cylinder and will not hold position when air pressure is exhausted or the directional valve is centered. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
