The AirTAC Airtac SC40 Standard Cylinder SC40X22 is a genuine double-acting standard air cylinder with a Ø40mm bore and 22mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X22 is a compact-stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. With a 40 mm bore and a short 22 mm stroke, it produces a push force of 628 N at 0.5 MPa (1130 N at 0.9 MPa), making it ideal for clamping, ejecting, and short-transfer tasks where space is tight.
This model features a 16 mm diameter piston rod with M12x1.25 threads and a PT1/4 port. The body length A is 142 mm, giving a total extended length of approximately 164 mm. Adjustable air cushioning at both ends decelerates the piston smoothly, protecting end caps during high-cycle operation.

The 22 mm stroke and 628 N force at 0.5 MPa suit compact fixture clamps on CNC routers and drilling jigs, where minimal travel and high holding force are needed.
Ideal for ejecting small plastic or metal parts from injection moulds or stamping dies. The short, fast stroke clears parts reliably without over-travel.
Operates small diverter gates or stops on packaging conveyors. The tie-rod construction handles repetitive cycling in dusty industrial environments.
For applications needing slightly more force in the same bore family, step up to the SC50 (982 N at 0.5 MPa). If a shorter body is required, the SC32 delivers 402 N at 0.5 MPa. The 22 mm stroke is a standard offering within the 40 mm bore’s 1200 mm maximum standard stroke range.
When replacing an existing cylinder, match these five points: 40 mm bore, 22 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no magnet. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.7 MPa (7 bar) supply pressure, the theoretical push force is 879 N. The pull force on the retract stroke is 528 N at 0.5 MPa due to the rod area reduction.
This basic model (SC40X22) ships without mounting accessories. You can order the rear single clevis bracket separately using part code F-SC40CA, or specify the suffix code SC40X22CA to include it pre-assembled.
