The AirTAC Airtac SC40 Standard Cylinder SC40X225S 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 AirTAC SC40X225S is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 225 mm stroke suit medium-force linear tasks where space is constrained, and the built-in magnet allows barrel-mounted CMSG/DMSG/EMSG sensors to confirm piston position without extra brackets.
This tie-rod design uses a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston quietly at each end. The total extended body length is approximately 367 mm (body length A of 142 mm plus the 225 mm stroke).

The 628 N push force at 0.5 MPa easily diverts cartons or packages on a conveyor line. The 225 mm stroke provides enough reach for standard chute widths, and the magnetic piston enables end-of-stroke sensing for high-cycle counting.
Delivers 1130 N of clamping force at 0.9 MPa for holding workpieces during drilling or light assembly. The adjustable cushion protects tooling from impact damage at the end of the 225 mm stroke.
Operates louvres or dampers in agricultural ventilation systems. The TPU seals handle -20 to +70 °C ambient temperatures, and the magnetic piston provides feedback that the damper is fully open or closed.
Choose the SC40 bore for push forces around 628 N at 0.5 MPa. If your load requires roughly 982 N, step up to the SC50 bore. For lighter, faster applications near 402 N, the SC32 bore may save space and air consumption. This 225 mm stroke is within the 1200 mm maximum standard stroke for the 40 mm bore.
When replacing an existing cylinder, match five points: 40 mm bore, 225 mm stroke, PT1/4 port thread, the built-in magnet (suffix -S), and the basic mounting style. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 reaches 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston. This allows you to clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without external flags or brackets.
