The AirTAC Airtac SC40 Standard Cylinder SC40X25FA is a genuine double-acting standard air cylinder with a Ø40mm bore and 25mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X25FA is a double-acting single-rod tie-rod cylinder with a 40 mm bore and a compact 25 mm stroke, equipped with a front rectangular flange (FA) for direct panel mounting. At 0.5 MPa operating pressure it provides 628 N of push force and 528 N of pull force, driven by a 16 mm diameter piston rod with an M12x1.25 male thread.
Its adjustable pneumatic cushion at both ends decelerates the piston smoothly over a 21 mm cushion length, reducing end-of-stroke impact. The cylinder body length is 142 mm, giving a total extended length of approximately 167 mm. The standard PT1/4 port and TPU seals suit filtered-air service from -20 to +70 °C. The front flange mounting accessory code is F-SC40FA.

The 25 mm stroke and front flange mount make this cylinder ideal for compact clamping fixtures on CNC machining centres, where rigid panel mounting and quick, repeatable linear motion are essential.
Delivering 628 N of push force, the SC40X25FA can reliably eject small parts from a conveyor line or stamping die, with the short stroke minimizing cycle time.
Used in benchtop pneumatic presses, this cylinder applies controlled force for inserting bearings or pins. The front flange provides stable alignment against the press frame.
Choose the SC40 bore when your application needs around 628 N of push force at 0.5 MPa; if you require more force, stepping up to the SC50 bore delivers 982 N at the same pressure. For lighter, more compact installations, the SC32 bore offers 402 N. The 25 mm stroke is a standard length well within the 1200 mm maximum for this bore, making it a stock item.
To ensure a correct replacement, match five points: 40 mm bore, 25 mm stroke, PT1/4 port thread, FA front flange mounting, and the absence of a magnet. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.7 MPa operating pressure, the theoretical push force is 879 N. The pull force on the return stroke is lower due to the 16 mm rod area and equals 528 N at 0.5 MPa. For the maximum operating pressure of 0.9 MPa, the push force reaches 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. The mounting dimensions, body length (142 mm A-dimension), and front flange bolt pattern are specific to the SC family. It is a direct replacement only for another AirTAC SC40 cylinder with matching bore, stroke, port, and FA mounting.
