The AirTAC Airtac SC40 Standard Cylinder SC40X225SN is a genuine double-acting standard air cylinder with a Ø40mm bore and 225mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X225SN is a 40 mm bore, 225 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It delivers 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa, making it a capable mid-range actuator for general industrial automation.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, enabling precise end-of-stroke detection without external brackets. The -N suffix specifies NBR (nitrile) seals, and the 16 mm diameter piston rod with M12x1.25 thread provides solid mechanical connection. The adjustable air cushion (21 mm length) decelerates the piston smoothly at each end of the 225 mm stroke.

The 225 mm stroke and 628 N push force at 0.5 MPa reliably actuate diverter gates and product stops on medium-speed packaging conveyors, with the built-in magnet providing sensor feedback for cycle counting.
Delivers consistent clamping pressure in machining and assembly fixtures. The NBR seals offer good wear resistance in typical factory air conditions, and the 16 mm rod resists deflection under axial load.
Ideal for pushing cartons or totes off a line. The adjustable cushion absorbs impact at the end of the 225 mm stroke, protecting the cylinder and product, while the magnetic piston allows easy integration of position sensors.
For applications requiring slightly more force, consider stepping up to the 50 mm bore SC50 series, which provides 982 N at 0.5 MPa. If space is a constraint, the 32 mm bore SC32 series offers 402 N at the same pressure. The SC40X225SN is a standard-stroke model (max standard stroke for 40 mm bore is 1200 mm).
When replacing an existing cylinder, match five key points: 40 mm bore, 225 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the NBR seal material. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard operating pressure of 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, push force increases to 879 N. The maximum operating pressure of 1.0 MPa yields a theoretical push force of approximately 128 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's sensor groove to detect piston position without any additional mounting hardware.
