The Airtac SC40X300 is a double-acting tie-rod standard cylinder from the AirTAC SC series with a 40 mm bore, 300 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), 40×300 = 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
- Material-handling and palletising equipment
- Bottling, filling and capping machines
- Wood, stone and metal working machines
- Door, gate and damper actuation
- Like-for-like replacement of an Airtac SC40X300
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 SC40X300S and AirTAC CMSG, DMSG or EMSG switches.
Frequently asked questions
How much force does it give?
At 0.5 MPa the 40 mm bore gives about 628.3 N pushing and 527.8 N pulling with its 16 mm rod. At the 1.0 MPa maximum the push force doubles to about 1,256.6 N.
Can I add a sensor to it?
Not to this version: SC40X300 has no piston magnet. Choose the S version for switch sensing.
Which fittings do I need?
The ports are 1/4″ with standard PT thread; G or NPT threads are a separate order code. Use push-in or speed-control fittings of the same thread and tube size suited to the flow.
