The Airtac SC50X25 is a double-acting tie-rod standard cylinder from the AirTAC SC series with a 50 mm bore, 25 mm stroke and adjustable air cushions at both ends. It is the version without a piston magnet (no S in the code), basic mounting and standard TPU seals.
Reading the code: SC = standard cylinder (double acting), 50×25 = bore x stroke in mm; no S = without magnet; no mounting, seal or thread suffix means basic mounting, TPU seals and PT port thread.

Typical applications
- Door, gate and damper actuation
- Bottling, filling and capping machines
- Wood, stone and metal working machines
- Lifting, pushing and transfer on conveyor lines
- Like-for-like replacement of an Airtac SC50X25
Compatibility and replacement
Per AirTAC, an SC cylinder is shorter than an ISO 15552 cylinder of the same bore, so it is not a dimensional drop-in for ISO 15552 cylinders from other makers. It does accept AirTAC SC/SAU-series mounting accessories (LB foot, FA/FB flange, CA/CB clevis, TC trunnion) and rod-end joints. If you need position sensing, order the magnet version SC50X25S and AirTAC CMSG, DMSG or EMSG switches.
Frequently asked questions
How much force does it give?
At 0.5 MPa the 50 mm bore gives about 981.7 N pushing and 824.7 N pulling with its 20 mm rod. At the 1.0 MPa maximum the push force doubles to about 1,963.5 N.
How do I set the cushion?
Turn the cushion needle screws on the front and rear covers. The cushion acts over the last 21 mm of stroke; adjust until the piston decelerates smoothly at the end of stroke without striking the cover.
Is SC50X25 a standard stroke?
25 mm is a standard stroke for the 50 mm bore in the AirTAC catalog, where the standard range goes up to 1200 mm.
