The AirTAC SC40 Standard Cylinder SC40X40FA is a genuine double-acting standard air cylinder with a Ø40mm bore and 40mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X40FA is a double-acting tie-rod cylinder with a 40 mm bore and a short 40 mm stroke, delivering 628 N of push force at 0.5 MPa (1130 N at the maximum operating pressure of 0.9 MPa). The 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration in a compact package, with the body length A measuring just 142 mm.
This model is factory-configured with an FA front rectangular flange (accessory F-SC40FA), allowing the cylinder to be rigidly mounted to a panel or machine frame from the rod-end cap. The standard PT1/4 port thread and TPU seals suit general industrial environments operating between -20 and +70 °C.

The 40 mm stroke and front flange mount make this cylinder ideal for compact clamping fixtures on CNC machining centers, where rigid end-mounting and repeatable force are essential.
Delivers a quick, controlled push to eject small components from an assembly line conveyor, with the 21 mm cushion absorbing impact at the end of the short, rapid cycle.
Generates up to 1130 N of force at 0.9 MPa for light press-fit operations, inserting bearings or bushings into housings with a consistent, guided linear motion.
For applications requiring more force, stepping up to the 50 mm bore SC50 series provides 982 N of push at the same 0.5 MPa pressure. If a shorter overall length is critical, the 32 mm bore SC32 series offers a 140 mm body length. To ensure a correct replacement, match five key points: 40 mm bore, 40 mm stroke, PT1/4 port thread, FA front flange mounting, and the absence of a built-in magnet.
Quick checklist
At 0.7 MPa operating pressure, the SC40X40FA generates 879 N of push force. The pull force at the same pressure is lower due to the rod area, delivering 528 N at 0.5 MPa.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (A=142 mm) than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable. Replace only with another AirTAC SC40 tie-rod cylinder matching the exact bore, stroke, and FA front flange mount.
