The AirTAC Airtac SC40 Standard Cylinder SC40X150N is a genuine double-acting standard air cylinder with a Ø40mm bore and 150mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X150N is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 628 N at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore and 150 mm stroke, it uses a 16 mm diameter piston rod and PT1/4 ports, making it a capable mid-range actuator for general industrial automation.
This model is fitted with NBR (nitrile) seals, offering good resistance to oils and wear in standard temperature environments. The cylinder body length is 142 mm, resulting in a total extended length of approximately 292 mm, and it features an adjustable pneumatic cushion of 21 mm at each end to decelerate the piston smoothly.

Provides a fast, decisive push to divert non-conforming products off a conveyor line, with 628 N of force at standard line pressure.
Used in jigs to hold components during drilling or welding, where the 150 mm stroke offers good clearance for part loading.
Operates a sliding gate on a hopper or chute, controlling the flow of granular materials with a robust 16 mm rod.
For applications requiring more force, consider stepping up to the 50 mm bore SC50 series, which provides 982 N of push at 0.5 MPa. If a lower force and smaller footprint are acceptable, the 32 mm bore SC32 series offers 402 N. This 150 mm stroke is within the standard range for a 40 mm bore (max 1200 mm).
To ensure a correct replacement, match these five points: 40 mm bore, 150 mm stroke, PT port thread, basic mounting (no accessories), and no magnet. This cylinder is a direct replacement for another AirTAC SC40X150N or an equivalent tie-rod cylinder with identical specifications.
Quick checklist
At the standard operating pressure of 0.5 MPa, 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.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so ISO 15552 mounts are not interchangeable. You must use AirTAC SC-specific mounting accessories, such as the F-SC40LB foot mount or F-SC40FA front flange.
