The AirTAC Airtac SC40 Standard Cylinder SC40X225STC 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 SC40X225STC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (up to 1130 N at 0.9 MPa). Its 40 mm bore and 225 mm stroke suit medium-force linear tasks, with a 16 mm diameter piston rod providing robust resistance to bending.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, plus a centre trunnion (TC) mount with TCM1 bracket for pivoting applications. The standard TPU seals offer reliable operation from -20 to +70 °C, and the PT1/4 port thread ensures straightforward pneumatic connections.

The 628 N push force and trunnion mount allow the SC40X225STC to pivot a diverter gate on a conveyor line, reliably sorting packages or components by size or destination.
With a 225 mm stroke and sensor-ready magnet, this cylinder provides precise, monitored clamping for CNC fixtures, welding jigs, and assembly stations, ensuring parts are held securely during machining.
The centre trunnion mount is ideal for swinging a hopper discharge door open and closed. The 1130 N maximum force handles sticky or heavy bulk materials in agricultural and processing equipment.
Choose the SC40 when your application needs around 628 N of force at standard plant pressure. If you require more thrust, stepping up to the SC50 bore provides 982 N at 0.5 MPa. For lighter, more compact needs, the SC32 delivers 402 N. Always match replacement cylinders on all five key points: 40 mm bore, 225 mm stroke, PT1/4 port thread, the TC centre trunnion mount (F-SC40TC), and the -S magnet for sensor compatibility.
At a 225 mm stroke, the 16 mm rod is well-supported for axial loads, but avoid significant side loading without an external guide. For applications with off-axis forces, consider pairing the cylinder with a linear guide rail to protect the rod bearing and seals from premature wear.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder (body length A is 142 mm). It is not dimensionally interchangeable. You must replace it with another AirTAC SC40 tie-rod cylinder matching the 225 mm stroke, PT port, TC mount, and magnet option.
