The AirTAC Airtac SC40 Standard Cylinder SC40X910S is a genuine double-acting standard air cylinder with a Ø40mm bore and 910mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X910S 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 operating pressure. Its 40 mm bore houses a 16 mm diameter piston rod with M12x1.25 male threads, and the 910 mm stroke is well within the 1200 mm maximum standard stroke for this bore size.
This model includes the -S suffix, indicating a built-in magnet along the barrel. This allows easy, non-invasive mounting of CMSG, DMSG, or EMSG reed and solid-state sensors to detect piston position for end-of-stroke signaling or mid-stroke confirmation. The cylinder uses a PT1/4 port and adjustable pneumatic cushioning to decelerate the piston smoothly over the final 21 mm of travel.

The 910 mm stroke and 628 N push force at 0.5 MPa are ideal for actuating diverter gates or stops on wide conveyor lines, with the built-in magnet providing reliable open/closed position feedback to the control system.
Delivers consistent 1130 N thrust at 0.9 MPa for pushing components along a 910 mm transfer rail in assembly cells. The adjustable cushion protects parts from impact damage at the end of stroke.
Suited for vertical or horizontal pick-and-place arms requiring a 910 mm reach. The 16 mm rod and 21 mm cushion length provide a balance of extension capability and end-of-stroke deceleration.
For applications needing slightly more force, stepping up to the 50 mm bore SC50 series provides 982 N of push force at 0.5 MPa. For a lighter, more compact solution, the 32 mm bore SC32 series offers 402 N. With a 910 mm stroke, ensure the 16 mm rod is adequately supported against side loads; if the load is not guided externally, consider adding an external guide rail or switching to a guided cylinder configuration to prevent rod bending.
When replacing an existing cylinder, match five key points: 40 mm bore, 910 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC series tie-rod cylinders of the same configuration.
Quick checklist
At the standard 0.5 MPa operating pressure, 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 increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
Yes. The -S suffix in the model code SC40X910S confirms a built-in magnet is integrated into the piston. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder's tie-rod barrel to detect position without any additional brackets.
