The AirTAC Airtac SC40 Standard Cylinder SC40X265SFA is a genuine double-acting standard air cylinder with a Ø40mm bore and 265mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X265SFA is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa, making it a reliable actuator for medium-duty linear tasks. Its 265 mm stroke and 16 mm diameter piston rod are supported by a 21 mm adjustable air cushion at each end, ensuring quiet, controlled deceleration even under frequent cycling.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke or mid-stroke position sensing without external brackets. The front rectangular flange (FA mount, accessory F-SC40FA) allows rigid panel or bulkhead installation, and the standard PT1/4 ports simplify pneumatic connections.

The built-in magnet and FA front flange mount allow this cylinder to be rigidly fixed to a machine frame, reliably ejecting parts while magnetic sensors confirm full extension and retraction for PLC cycle control.
With 628 N of force at standard line pressure, it powers a divert gate on a packaging conveyor. The adjustable cushion absorbs impact as the gate reaches its end position, reducing noise and wear.
Delivers up to 1130 N of clamping force at 0.9 MPa for holding workpieces during assembly or light machining. Magnetic sensors interlock with the machine control to prevent operation unless the part is clamped.
With a push force of 628 N at 0.5 MPa, the SC40X265SFA sits between the smaller SC32 (402 N) for lighter tasks and the larger SC50 (982 N) for heavier pressing or clamping. If your load exceeds 1130 N at the cylinder's maximum 1.0 MPa operating pressure, stepping up to a 50 mm bore is recommended.
For this 265 mm stroke, ensure the load is guided and side forces are minimized; the 16 mm rod can experience bending under off-axis loads. For exact drop-in replacement, match the 40 mm bore, 265 mm stroke, PT1/4 port thread, front flange (FA) mounting, and the integrated 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 force 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, so it is not dimensionally interchangeable. For a direct replacement, you must use another AirTAC SC tie-rod cylinder with a 40 mm bore, 265 mm stroke, front flange mount, and integrated magnet.
