The AirTAC Airtac SC40 Standard Cylinder SC40X25SCB is a genuine double-acting standard air cylinder with a Ø40mm bore and 25mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X25SCB is a compact-stroke double-acting cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable end-of-stroke deceleration for light, fast-cycling tasks.
This model is factory-equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a rear double clevis (CB) bracket for pivoting applications. The mounting accessory code is F-SC40CB, allowing the cylinder to swing freely in a single plane.

The short 25 mm stroke and pivoting CB mount make this cylinder ideal for quick-acting diverter gates on small conveyor lines, where sensor feedback confirms gate position.
Delivers 628 N of clamping force at standard shop air. The rear clevis allows the cylinder body to pivot, accommodating slight fixture misalignment in automated welding or assembly jigs.
Actuates small slide gates on seed or granular material hoppers. The magnetic piston enables end-of-stroke sensing to verify full open or closed status in dusty agricultural environments.
For higher thrust, step up to the 50 mm bore SC50 series, which provides 982 N at 0.5 MPa. For lower forces in a smaller envelope, the 32 mm bore SC32 series offers 402 N. When replacing, match all five key points: 40 mm bore, 25 mm stroke, PT port thread, the CB rear double clevis mount, and the -S magnet for sensor compatibility.
Quick checklist
At 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 reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is dimensionally interchangeable only with another AirTAC SC tie-rod cylinder matching the same bore, stroke, port thread, and mounting configuration.
