The AirTAC Airtac SC40 Standard Cylinder SC40X175N 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 AirTAC SC40X175N is a double-acting tie-rod cylinder with a 40 mm bore and 175 mm stroke, fitted with NBR (nitrile) seals for reliable operation in standard industrial environments. At 0.5 MPa it generates 628 N pushing force and 528 N pulling force, while the maximum operating thrust at 0.9 MPa reaches 1130 N, driven by a 16 mm diameter piston rod.
This model uses a PT1/4 port and an M12x1.25 rod thread, with a 21 mm adjustable air cushion at each end to decelerate the piston smoothly. The body length A is 142 mm, giving a total extended length of approximately 317 mm. As a genuine AirTAC actuator, it is built for dependable pneumatic service across automation tasks requiring a mid-range force output.

Actuates diverter gates on packaging and sorting conveyors. The 175 mm stroke provides sufficient travel for medium-width chute switching, while the NBR seals handle typical factory air supplies.
Delivers 628 N of clamping force at 0.5 MPa for holding workpieces during drilling, welding, or assembly. The adjustable cushion reduces impact at the end of the clamp stroke, protecting the fixture.
Provides the push stroke for light embossing, stamping, or forming operations. The 1130 N maximum thrust at 0.9 MPa handles repetitive pressing tasks in compact machine frames.
Choose the SC40 bore when your application needs around 628 N of force at 0.5 MPa. If your load requires more thrust, stepping up to the SC50 delivers 982 N at the same pressure; for a lighter, more compact solution the SC32 provides 402 N. Always match the replacement cylinder on five points: bore, stroke, port thread (PT), mounting accessory, and magnet option.
At a 175 mm stroke, the 16 mm rod is well-supported for axial loads. If you are applying any side load or the stroke is extended further, consider an external guide or a guided cylinder to protect the rod bearing from bending stress and premature seal wear.
Quick checklist
At 0.7 MPa operating pressure, the SC40X175N produces a theoretical pushing force of 879 N and a pulling force of 528 N. The maximum operating thrust at 0.9 MPa is 1130 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It directly replaces another AirTAC SC40 cylinder with the same stroke, PT port, and NBR seals.
