The AirTAC Airtac SC40 Standard Cylinder SC40X113 is a genuine double-acting standard air cylinder with a Ø40mm bore and 113mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X113 is a non-standard stroke variant in the AirTAC SC tie-rod cylinder family, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for a 113 mm stroke, making it a compact workhorse for short-to-medium linear moves.
This double-acting cylinder uses filtered air to power both extend and retract strokes, with a body length A of 142 mm for a total extended length of approximately 255 mm. The standard PT1/4 port and M12x1.25 rod thread ensure straightforward pneumatic connections, while the TPU seals suit ambient temperatures from -20 to +70 °C.

The 628 N push force at 0.5 MPa is well-suited for stopping light packages or actuating small diverter gates on conveyor lines, where the 113 mm stroke provides a defined retraction path.
Delivers controlled clamping pressure for jigs and assembly fixtures. The 16 mm rod and adjustable cushion help prevent part damage by softening the contact at the end of the 113 mm stroke.
Ideal for pushing small components off a slide or into a nest. The double-acting function ensures positive retraction, and the tie-rod construction allows for easy maintenance in high-cycle applications.
For applications needing slightly more force, stepping up to a 50 mm bore SC50 series provides 982 N of push at 0.5 MPa. If a shorter, standard stroke is acceptable, the SC40X100 delivers the same force in a slightly more compact envelope. This 113 mm stroke is non-standard, so confirm lead time with your AirTAC distributor.
When replacing an existing cylinder, match five key points: 40 mm bore, 113 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and the absence of a magnet. The SC series is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the cylinder provides 628 N pushing force and 528 N pulling force. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 1130 N. These values are based on the 40 mm bore and 16 mm rod diameter.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (A=142 mm) than an equivalent ISO 15552 profile cylinder. It is not dimensionally interchangeable. It should only replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port, and mounting.
