The AirTAC Airtac SC40 Standard Cylinder SC40X65S is a genuine double-acting standard air cylinder with a Ø40mm bore and 65mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X65S is a double-acting single-rod tie-rod cylinder with a 40 mm bore and 65 mm stroke, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. The 16 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration for consistent cycling.
This model includes the -S suffix, meaning a built-in magnet is embedded in the piston. This allows easy external mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel for contactless position feedback without extra brackets. The body length A is 142 mm, giving a total extended length of approximately 207 mm.

The 65 mm stroke and magnetic piston make this ideal for a small conveyor diverter gate, where end-of-stroke sensors confirm the gate is fully open or closed for lightweight package routing.
Delivers 628 N of clamping force at standard line pressure. The built-in magnet allows two sensors to verify both the clamped and retracted positions for a safety interlock circuit.
The smooth adjustable cushion and sensor-ready barrel suit a linear sampling mechanism, providing precise position confirmation for a probe or pipette in automated test equipment.
The SC40 bore sits between the compact SC32 (402 N push at 0.5 MPa) and the larger SC50 (982 N push at 0.5 MPa). If your load requires more force, stepping up to a 50 mm bore is recommended. For this 65 mm stroke, the standard tie-rod construction is rigid, but always ensure the load is axially aligned to prevent rod bending.
For a drop-in replacement, match five key points: the 40 mm bore, 65 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting style. This cylinder is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rod slots to detect piston position without any additional mounting hardware.
