The AirTAC Airtac SC40 Standard Cylinder SC40X107S is a genuine double-acting standard air cylinder with a Ø40mm bore and 107mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X107S is a double-acting tie-rod cylinder with a 40 mm bore and 107 mm stroke, delivering a push force of 628 N at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range linear tasks.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for non-contact position sensing. The standard TPU seals and PT1/4 ports suit filtered-air systems operating from -20 to +70 °C.

The 628 N push force at 0.5 MPa reliably actuates flap gates and diverters on medium-speed packaging conveyors, while the built-in magnet enables end-of-stroke confirmation.
With a 16 mm rod and 107 mm stroke, this cylinder suits part-clamping fixtures in light manufacturing. The adjustable cushion protects tooling from impact at cycle end.
The compact tie-rod body and sensor-ready barrel make it a practical choice for automated liquid sampling systems, where position feedback is required for sequence control.
For applications needing more force, the 50 mm bore SC50 series steps up to 982 N push at 0.5 MPa. If space is tight and less force is acceptable, the 32 mm bore provides 402 N. The 107 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
When replacing an existing cylinder, match five points: 40 mm bore, 107 mm stroke, PT1/4 port thread, the basic mounting style (no bracket), and the built-in magnet for sensor compatibility. This SC series is a tie-rod design and 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 reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston, so AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors can be clamped directly onto the barrel tie-rod slots for position detection.
