The AirTAC Airtac SC40 Standard Cylinder SC40X40SN 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 SC40X40SN is a compact double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa, ideal for short-stroke clamping and ejecting tasks. Its 40 mm bore houses a 16 mm diameter piston rod with M12x1.25 male threads, and the body length A measures just 142 mm, keeping the overall extended length to 182 mm.
This model is factory-equipped with a built-in magnet (-S suffix) so CMSG/DMSG/EMSG reed or solid-state sensors clip directly onto the barrel for non-contact position sensing. The NBR seal variant (-N suffix) provides reliable sealing in standard industrial environments, and PT1/4 ports ensure straightforward pneumatic connection.

Short 40 mm stroke with 628 N push force reliably ejects small stamped or molded parts from dies and fixtures.
Compact 182 mm extended length fits tight conveyor spaces to operate sorting gates with sensor-confirmed end-of-stroke.
Double-acting control with magnetic piston sensing ensures precise clamp/unclamp cycles on assembly jigs.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N at 0.5 MPa. If a shorter stroke suffices, the SC40X25 offers a 25 mm standard stroke. When replacing an existing cylinder, match five points exactly: 40 mm bore, 40 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the NBR seal material to maintain the same chemical resistance and temperature range.
Quick checklist
At 0.5 MPa air pressure, this 40 mm bore cylinder produces 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N.
Yes. The -S suffix in SC40X40SN indicates a built-in magnet on the piston. AirTAC CMSG, DMSG, or EMSG series sensors mount directly onto the tie-rod barrel to detect piston position without additional brackets.
