The AirTAC Airtac SC40 Standard Cylinder SC40X155 is a genuine double-acting standard air cylinder with a Ø40mm bore and 155mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X155 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 155 mm stroke. It generates a push force of 628 N at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa, driven by a 16 mm diameter piston rod.
This model features a compact body length A of 142 mm, resulting in a total extended length of approximately 297 mm. It includes PT1/4 ports, an M12x1.25 rod thread, and a 21 mm adjustable air cushion at both ends to decelerate the piston smoothly.

Provides the 628 N push force needed to reliably extend a stop pin or divert gate on a light-duty conveyor line, halting totes or small packages.
Delivers consistent clamping force for woodworking jigs or light assembly fixtures, where the 16 mm rod and adjustable cushion ensure a controlled, repeatable action.
Suitable as an actuator in small pneumatic presses for inserting grommets or forming thin sheet metal, leveraging its 1130 N maximum thrust at 0.9 MPa.
For applications requiring more force, consider stepping up to the 50 mm bore SC50 series, which provides 982 N of push force at 0.5 MPa. If a shorter, lighter cylinder is acceptable, the 32 mm bore SC32 delivers 402 N at the same pressure. The SC40X155 is a standard-stroke model within the 1200 mm maximum for this bore size.
When replacing an existing cylinder, ensure a 5-point match: 40 mm bore, 155 mm stroke, PT1/4 port thread, basic mounting (no brackets), and no built-in magnet. This tie-rod cylinder is dimensionally shorter than an ISO 15552 profile cylinder and is not a drop-in replacement for that standard.
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, the push force increases to 1130 N.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable. It should only replace another AirTAC SC tie-rod cylinder with the same bore, stroke, port, and mounting configuration.
