The AirTAC Airtac SC40 Standard Cylinder SC40X175FA is a genuine double-acting standard air cylinder with a Ø40mm bore and 175mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X175FA is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 175 mm stroke. At 0.5 MPa, it generates a push force of 628 N, making it a capable mid-range actuator for linear motion tasks.
This model features a 16 mm diameter piston rod with an M12x1.25 thread and a PT1/4 port. The front rectangular flange mount (FA, accessory F-SC40FA) allows secure panel or bulkhead installation, while the 21 mm adjustable air cushion at each end decelerates the piston smoothly to reduce end-of-stroke impact.

The 628 N push force at 0.5 MPa is well-suited for pneumatic clamping and work-holding fixtures in CNC machining and assembly cells.
With a 175 mm stroke, this cylinder effectively pushes or diverts components between conveyor lanes or indexing stations.
Delivers controlled linear force for light pressing, stamping, or forming operations where a compact tie-rod cylinder is needed.
Select the SC40X175FA when the 32 mm bore’s 402 N push force is insufficient but the larger 50 mm bore’s 982 N is excessive for your application. The front flange mount is ideal for applications where the cylinder body must be rigidly fixed to a machine face.
For strokes of 175 mm, side loading is a key consideration. Ensure the load is guided externally if any lateral force is present, as the 16 mm rod is not designed to bear bending moments. When replacing an existing cylinder, match the 40 mm bore, 175 mm stroke, PT1/4 port, FA front flange mount, and confirm the magnet requirement.
Quick checklist
At 0.5 MPa (5 bar) air pressure, the push force is 628 N. At the maximum operating pressure of 0.9 MPa, the theoretical push force reaches 1130 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder of the same bore and stroke. It is dimensionally interchangeable only with another AirTAC SC tie-rod cylinder matching the 40 mm bore, 175 mm stroke, and FA front flange mount.
