The AirTAC Airtac SC40 Standard Cylinder SC40X270 is a genuine double-acting standard air cylinder with a Ø40mm bore and 270mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X270 is a genuine AirTAC single-rod, double-acting tie-rod cylinder with a 40 mm bore and 270 mm stroke. Operating on filtered air at 0.15–1.0 MPa, it produces a push force of 628 N at 0.5 MPa and 1130 N at the maximum 0.9 MPa operating pressure, driven by a 16 mm diameter piston rod.
With a compact body length A of 142 mm, the total extended length is approximately 412 mm. The cylinder includes an adjustable pneumatic cushion (21 mm length) at both ends to decelerate the piston, reducing end-of-stroke impact. Standard PT1/4 ports and an M12x1.25 rod thread are fitted, with TPU seals for a standard operating temperature range of -20 to +70 °C.

Provides the 628 N push force at 0.5 MPa needed to actuate diverter gates on packaging or assembly conveyors, with the 270 mm stroke offering ample travel for wide chute openings.
Delivers consistent clamping pressure for medium-duty CNC fixtures and welding jigs. The adjustable cushion protects the workpiece from impact damage during rapid clamp cycles.
Ideal for ejecting parts from a production line or pushing cartons onto a takeaway conveyor, where the 270 mm stroke clears the product from the tooling area reliably.
For applications requiring slightly more force, stepping up to the 50 mm bore SC50 series provides 982 N of push force at 0.5 MPa. If a lighter, more compact solution is acceptable, the 32 mm bore SC32 series offers 402 N at the same pressure. This 270 mm stroke model is within the 1200 mm maximum standard stroke for the 40 mm bore.
When replacing an existing cylinder, match five key points: the 40 mm bore, 270 mm stroke, PT1/4 port thread, basic (no bracket) mounting configuration, and the absence of a built-in magnet. The SC series is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard 0.5 MPa operating pressure, 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. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is a direct dimensional match only for another AirTAC SC tie-rod cylinder with the same bore, stroke, port thread, and mounting configuration.
