The AirTAC Airtac SC40 Standard Cylinder SC40X235S is a genuine double-acting standard air cylinder with a Ø40mm bore and 235mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X235S is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa. With a 40 mm bore and a 235 mm stroke, this model is well within the 1200 mm maximum standard stroke for this bore size. The 16 mm diameter piston rod and PT1/4 port provide a robust yet compact actuation package.
This -S variant includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable end-of-stroke detection. The cylinder uses a 21 mm adjustable air cushion to decelerate the piston smoothly, reducing impact noise and vibration. Operating on filtered air from 0.15 to 1.0 MPa, it is suitable for a wide range of industrial automation tasks.

Actuates diverter gates on conveyor lines. The 235 mm stroke provides ample travel for medium-width belts, and the built-in magnet enables sensor feedback to confirm gate position.
Provides 628 N of clamping force at standard line pressure. The adjustable cushion protects delicate parts during high-speed clamping cycles by decelerating the rod before contact.
Delivers up to 1130 N of push force for light press-fit or insertion operations. The 16 mm rod offers good column strength for straight-line pushing tasks within the 235 mm stroke.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N at 0.5 MPa, while the 32 mm bore SC32 offers 402 N for lighter, more compact requirements. This SC40X235S model is a basic configuration with a magnet but no additional mounting accessories; it requires the user to provide a rigid mounting surface and ensure proper rod alignment.
To replace an existing cylinder, match five key points: bore (40 mm), stroke (235 mm), PT port thread, the built-in magnet (-S suffix), and the tie-rod mounting footprint. Note that the SC series is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders. For strokes over 300 mm, consider external guides to protect the rod from side loads.
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 designates a built-in magnet. You can directly clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the barrel to detect piston position without any additional brackets.
