The AirTAC Airtac SC40 Standard Cylinder SC40X180SFA is a genuine double-acting standard air cylinder with a Ø40mm bore and 180mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X180SFA is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (879 N at 0.7 MPa). Its 40 mm bore and 180 mm stroke suit medium-force clamping and positioning tasks where a compact, non-ISO envelope is needed.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, plus a front rectangular flange (FA, part F-SC40FA) for rigid panel mounting on the rod side. The 16 mm diameter rod and 21 mm adjustable air cushion provide smooth end-of-stroke deceleration without external shock absorbers.

The built-in magnet allows CMSG/DMSG sensors to confirm clamp position, ideal for automated CNC fixture clamping with 628 N holding force at 0.5 MPa.
Front flange mounting secures the cylinder to a conveyor frame, extending a stop pin 180 mm to divert or hold light packages on the line.
The FA flange bolts directly to a machine panel, providing a stable base for a 180 mm pressing or forming stroke in assembly fixtures.
Choose the SC40 when your application needs around 628 N at 0.5 MPa. If you require more force, step up to the SC50 bore delivering 982 N at the same pressure; for a lighter, more compact solution, the SC32 provides 402 N. Always match the replacement cylinder on five points: 40 mm bore, 180 mm stroke, PT port thread, FA front flange mounting, and the built-in magnet for sensor compatibility.
At 180 mm stroke, the 16 mm rod is well-supported for axial loads. If side loads are present, consider an external guide rail or a guided cylinder to protect the rod bearing from bending stress.
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 at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (A=142 mm) than an equivalent ISO 15552 cylinder. It is not dimensionally interchangeable. Replace only with another AirTAC SC40 tie-rod cylinder matching the bore, stroke, PT port, FA mount, and magnet option.
