The AirTAC Airtac SC40 Standard Cylinder SC40X265S 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 SC40X265S is a tie-rod double-acting cylinder with a 40 mm bore and 265 mm stroke, producing 628 N of push force at 0.5 MPa. Its 16 mm diameter rod and PT1/4 port ensure a robust connection for pneumatic circuits, while the 21 mm air cushion at each end decelerates the piston smoothly.
This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to mount directly on the barrel for precise end-of-stroke detection. The 265 mm stroke is a non-standard length, offering a custom fit for applications where the standard 250 mm or 300 mm options are not ideal.

Ideal for pusher or diverter stations on conveyors where sensor confirmation of the cylinder's position is required for automated sortation.
Provides consistent clamping force in machining fixtures, with the magnetic sensor verifying the clamp is fully engaged before a cycle starts.
Used in case packers and palletizers where the 265 mm stroke positions product, and the sensor signals the control system for the next step.
When selecting a cylinder, the SC40X265S provides a mid-range force between the smaller 32 mm bore (402 N at 0.5 MPa) and the larger 50 mm bore (982 N). For strokes over 300 mm on a 40 mm bore, be mindful of side loads; an external guide or guided cylinder is recommended to prevent rod bending. To ensure a correct replacement, match the 40 mm bore, 265 mm stroke, PT1/4 port thread, basic mount, and the -S magnet option.
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.
Yes, the -S suffix indicates a built-in magnet. This allows you to use AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors, which clamp directly onto the cylinder's tie-rod barrel.
