The AirTAC Airtac SC40 Standard Cylinder SC40X15 is a genuine double-acting standard air cylinder with a Ø40mm bore and 15mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X15 is a compact-stroke double-acting pneumatic cylinder built on the SC tie-rod platform. With a 40 mm bore and a short 15 mm stroke, it delivers a push force of 628 N at 0.5 MPa (1130 N at the maximum operating pressure of 0.9 MPa), making it a strong actuator for clamping, ejecting, or positioning tasks where travel is minimal.
This model features a 16 mm diameter piston rod with an M12x1.25 male thread and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston at end-of-stroke to reduce impact, while the standard TPU seals suit operating temperatures from -20 to +70 °C. The total extended body length is approximately 157 mm (body length A of 142 mm plus the 15 mm stroke).

The 15 mm stroke and 628 N push force at 0.5 MPa make this cylinder ideal for pneumatic clamping fixtures where only a brief linear advance is needed to secure a workpiece.
Compact body length (approx. 157 mm extended) fits tight machine envelopes. Use the SC40X15 for high-cycle ejector or light stamping duties requiring a robust 16 mm rod.
Quick 15 mm travel is well-suited for actuating small diverters or gates on conveyor lines, where the double-acting air control ensures positive retraction and extension.
For applications requiring slightly more force in the same bore class, consider stepping up to the SC50 series (982 N push at 0.5 MPa). If a shorter-stroke 32 mm bore would suffice, the SC32 delivers 402 N at 0.5 MPa. When replacing an existing cylinder, match five points: 40 mm bore, 15 mm stroke, PT1/4 port thread, the specific mounting accessory (this is a basic body, so order any required mount separately, e.g. F-SC40LB for foot mounting), and confirm whether a magnet is needed (this code has no -S magnet).
Quick checklist
At 0.5 MPa the push force is 628 N and the pull force is 528 N. At 0.7 MPa push rises to 879 N, and at the maximum operating pressure of 0.9 MPa it reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
This basic model (no mounting suffix) has the standard SC tie-rod body with threaded end-cap holes. For surface mounting you will need an accessory bracket such as the LB foot mount (F-SC40LB) or FA/FB flange mounts, ordered separately. The cylinder itself does not include a mounting bracket.
