The AirTAC Airtac SC32 Standard Cylinder SC32X25N is a genuine double-acting standard air cylinder with a Ø32mm bore and 25mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X25N is a compact double-acting tie-rod cylinder with a 32 mm bore and a short 25 mm stroke, fitted with NBR (nitrile) seals for general-purpose pneumatic service. It generates 402 N of push force at 0.5 MPa and 724 N at the maximum operating pressure of 0.9 MPa, making it ideal for light clamping and ejector tasks.
This model uses a 12 mm diameter piston rod with an M10x1.25 rod thread and PT1/8 ports. The body length A is 140 mm, giving a total extended length of approximately 165 mm. The adjustable air cushion (21 mm length) decelerates the piston smoothly at end-of-stroke to reduce impact noise.

The 25 mm stroke and 12 mm rod provide a quick, controlled push to eject small plastic or metal components from a fixture or die in automated assembly cells.
With 724 N of force at 0.9 MPa, this cylinder applies consistent pressure for light-duty clamping of workpieces during gluing, soldering, or inspection processes.
Actuates small diverter gates on compact conveyor systems. The short stroke and fast cycle time suit high-speed sorting of lightweight packages.
Choose the SC32 bore for light-duty applications needing up to 402 N at 0.5 MPa. If your force requirement exceeds this, step up to the SC40 bore, which provides 628 N at the same pressure. For this 25 mm stroke, side-load concerns are minimal, but always align the rod with the load axis to protect the rod bearing.
When replacing an existing cylinder, match five key points: 32 mm bore, 25 mm stroke, PT1/8 port thread, NBR seal material, and basic (no bracket) mounting. The SC32X25N is a direct replacement for another AirTAC SC32X25N cylinder only.
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 SC32X25N is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. For load-holding applications, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
