The AirTAC Airtac SC40 Standard Cylinder SC40X395S is a genuine double-acting standard air cylinder with a Ø40mm bore and 395mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X395S is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (879 N at 0.7 MPa). Its 40 mm bore houses a 16 mm diameter piston rod, and the 395 mm stroke suits mid-reach material-transfer or pressing tasks where sensor confirmation is required.
A built-in magnet (the -S suffix) runs the full stroke length, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The adjustable air cushion (21 mm) decelerates the end-of-stroke mass smoothly, and the PT1/4 port threads accept standard pneumatic fittings.

The built-in magnet lets CMSG/DMSG sensors confirm mid-stroke and end-of-stroke positions, making the SC40X395S ideal for diverting packages on a conveyor where the controller needs real-time cylinder-state feedback.
With 879 N of force at 0.7 MPa, this 40 mm bore cylinder inserts bearings or bushings into housings. The 395 mm stroke provides the reach needed for deep fixtures, and the adjustable cushion protects the part from impact damage.
Use the SC40X395S to raise and lower a product stop gate on a packaging line. The magnetic piston confirms the gate is fully retracted before the next pallet advances, preventing jams and line stoppages.
Choose the SC40X395S when your application needs roughly 628 N of push force at standard plant pressure. If you require more force, the SC50 series provides 982 N at 0.5 MPa in the same tie-rod format. For strokes of 300 mm or more, be cautious with side loads—an unsupported 16 mm rod at 395 mm extension can bend under lateral force; add an external linear guide or switch to a guided cylinder if the load is not perfectly axial.
When replacing an existing unit, match five points: 40 mm bore, 395 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor mounting, and the basic (no bracket) mounting style. This cylinder is a tie-rod design, not an ISO 15552 profile, so it is dimensionally shorter and not interchangeable with ISO 15552 cylinders.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder pushes with 628 N and pulls with 528 N. At 0.7 MPa, push force rises to 879 N. The maximum operating pressure is 1.0 MPa, delivering a theoretical push of 1130 N.
Yes. The -S suffix in SC40X395S indicates a factory-installed magnetic piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel to detect piston position without external brackets or flags.
