The AirTAC Airtac SC40 Standard Cylinder SC40X115S is a genuine double-acting standard air cylinder with a Ø40mm bore and 115mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X115S is a double-acting pneumatic tie-rod cylinder with a 40 mm bore and 115 mm stroke, delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). The built-in magnet (suffix -S) allows barrel-mounted CMSG, DMSG, or EMSG sensors to detect piston position without external brackets, simplifying automation setup.
With a 16 mm diameter piston rod and M12x1.25 rod thread, this cylinder handles moderate clamping and pressing tasks. The adjustable air cushion (21 mm length) decelerates the piston smoothly at stroke ends, reducing impact noise. Its PT1/4 ports and compact tie-rod body (A=142 mm) make it a genuine AirTAC workhorse for general industrial automation.

The 115 mm stroke and magnetic piston sensing make this cylinder ideal for conveyor diverters and part stops, where end-of-stroke confirmation ensures reliable material handling sequences.
With 628 N of push force at 0.5 MPa, the SC40X115S suits light press-fit operations, riveting, or staking in benchtop assembly cells, especially where piston position feedback is required.
The 16 mm rod and adjustable cushion provide stable clamping force for CNC fixtures and welding jigs. The built-in magnet enables clamp-open and clamp-closed verification via reed switches.
Choose the SC40 bore for applications needing 500–630 N at standard plant pressure. If your load approaches 800 N, step up to the SC50 bore (982 N push at 0.5 MPa) for a safety margin. For lighter, faster cycling below 400 N, the SC32 bore (402 N at 0.5 MPa) offers a more compact footprint.
This 115 mm stroke is within the 1200 mm maximum standard stroke for bore 40. When replacing an existing cylinder, match five points: 40 mm bore, 115 mm stroke, PT1/4 port thread, the -S magnet option for sensor compatibility, and any mounting accessory. If side loads are present, use an external guide rail—tie-rod cylinders are not designed to support radial forces on the rod.
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 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 indicates a built-in magnet on the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the barrel tie-rods to detect piston position without additional mounting hardware.
