The AirTAC Airtac SC32 Standard Cylinder SC32X55 is a genuine double-acting standard air cylinder with a Ø32mm bore and 55mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X55 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 make it a reliable workhorse for short-stroke clamping and ejecting tasks.
With a body length of just 140 mm, this 32 mm bore cylinder fits tight machine envelopes. The standard PT1/8 ports and M10x1.25 rod thread simplify pneumatic connections, while the TPU seals provide smooth operation from -20 to +70 °C.

The 402 N force at 0.5 MPa is ideal for fixturing and clamping small components during assembly or machining, where a short 55 mm stroke is sufficient.
Use the SC32X55 to eject lightweight parts from a conveyor line. Its fast 30-800 mm/s speed range keeps cycle times short.
Apply consistent pressure for label or sticker application. The adjustable cushion prevents impact damage to delicate parts at the end of the stroke.
Choose the SC32X55 when your application needs up to 402 N of force at standard plant air pressure. If you require more force, step up to the SC40 bore which provides 628 N at 0.5 MPa. For strokes over 300 mm, consider an external guide to protect the 12 mm rod from side-load bending.
To guarantee a drop-in replacement, match five key points: 32 mm bore, 55 mm stroke, PT port thread, basic mounting (no brackets), and confirm the magnet option (this model has no built-in magnet).
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.
Yes, if the original is an AirTAC SC32 tie-rod cylinder with a 55 mm stroke, PT ports, and no magnet. Always verify the port thread, mounting, and rod thread (M10x1.25) match your existing setup.
