The AirTAC Airtac SC40 Standard Cylinder SC40X140S is a genuine double-acting standard air cylinder with a Ø40mm bore and 140mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X140S is a double-acting pneumatic cylinder with a 40 mm bore and 140 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. 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 be clamped directly onto the tie-rod barrel for non-contact position sensing. The compact body length of 142 mm plus stroke keeps the overall footprint shorter than an ISO 15552 cylinder.

The 140 mm stroke and magnetic piston make this cylinder ideal for diverting packages on conveyor lines, with sensors confirming gate position at each cycle.
Delivers consistent 628 N clamping force at standard line pressure for holding components during gluing or ultrasonic welding processes.
The built-in magnet enables precise end-of-stroke detection for cyclic testing of materials, ensuring accurate cycle counting and data logging.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push at 0.5 MPa. If space is a constraint and less force is acceptable, the 32 mm bore SC32 series offers 402 N at the same pressure. The 140 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
When replacing an existing cylinder, match five key points: 40 mm bore, 140 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the basic mounting configuration. Always verify rod thread (M12x1.25) and cushion length.
Quick checklist
At 0.5 MPa, the cylinder provides 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
Yes. The -S suffix indicates a built-in magnet on the piston. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG reed or solid-state sensors onto the barrel for non-contact position feedback.
