The AirTAC Airtac SC40 Standard Cylinder SC40X10S is a genuine double-acting standard air cylinder with a Ø40mm bore and 10mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X10S is a compact-stroke single-rod double-acting cylinder with a 40 mm bore and a 10 mm stroke, pre-equipped with a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors. At 0.5 MPa it generates 628 N extending and 528 N retracting, making it ideal for short-throw clamping or ejector tasks.
This tie-rod cylinder uses a 16 mm diameter piston rod with an M12x1.25 thread and PT1/4 ports. The total extended body length is approximately 152 mm (142 mm body length A + 10 mm stroke), and the adjustable air cushion at each end provides 21 mm of deceleration to protect the end caps during high-speed cycling.

The built-in magnet allows CMSG/DMSG sensors to confirm full retraction after ejecting small components from a fixture, ensuring the 10 mm stroke is complete before the next cycle.
Delivers 628 N of clamping force at 0.5 MPa to hold thin workpieces during light assembly or gluing, where a 10 mm stroke is sufficient for clearance and engagement.
Operates a small diverter gate on a conveyor line, using the sensor to signal gate position. The 40 mm bore provides enough force to shift lightweight packages reliably.
For applications needing slightly more force, stepping up to the 50 mm bore SC50 series provides 982 N push at 0.5 MPa. If a lower force is acceptable, the 32 mm bore SC32 series offers 402 N. To ensure a correct replacement, match five key points: the 40 mm bore, 10 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting style. For strokes of 300 mm or longer, always evaluate side-load conditions and consider an external guide to protect the 16 mm rod from bending.
Quick checklist
At 0.7 MPa operating pressure, the extending (push) force is 879 N and the retracting (pull) force is 528 N. The maximum theoretical force at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet is installed in the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the tie-rod barrel to detect piston position.
