The AirTAC SC40 Standard Cylinder SC40X30STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 30mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X30STC is a compact double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa) from a 40 mm bore. With a 30 mm stroke and a 16 mm diameter piston rod, it suits short-throw clamping, ejecting, and sorting tasks where space is tight.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, plus a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC40TC) for pivoting actuation. The TPU seals and PT1/4 ports keep it reliable in standard -20 to +70 °C environments.

The 30 mm stroke and 628 N push force eject small components from fixtures or nests in automated assembly cells, with magnetic sensors confirming rod position at each cycle.
Centre trunnion mounting lets the cylinder pivot as it extends, ideal for actuating a small diverter gate on a packaging conveyor where space is limited.
Delivers consistent clamping force for gluing, welding, or test fixtures. The short stroke minimises cycle time while the magnet enables end-of-stroke sensing.
For a 40 mm bore at 30 mm stroke, the SC40X30STC provides 628 N push at 0.5 MPa. If your load requires more force, step up to the SC50 series (982 N push at 0.5 MPa); for a lighter, faster cycle, the SC32 (402 N) may suffice. The short 30 mm stroke keeps the rod well-supported, but always avoid direct side loads on the rod.
When replacing an existing cylinder, match five points: 40 mm bore, 30 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet for sensor compatibility. This ensures identical fit and function.
Quick checklist
At 0.5 MPa the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix denotes a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clip directly onto the barrel to detect piston position without additional brackets.
