The AirTAC Airtac SC40 Standard Cylinder SC40X19S is a genuine double-acting standard air cylinder with a Ø40mm bore and 19mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X19S is a compact-stroke double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore houses a 16 mm diameter piston rod with M12x1.25 male threads, and the body length A measures just 142 mm, making it suitable for tight installations where a short linear movement is required.
This model includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the tie-rod barrel for reliable end-of-stroke position sensing. The adjustable air cushion at each end decelerates the piston smoothly within a 21 mm cushion zone, protecting the end caps during high-cycle operation.

The built-in magnet enables direct mounting of CMSG/DMSG sensors for precise position feedback in automated pick-and-place or sorting mechanisms.
With a 19 mm stroke and 628 N push force, this cylinder suits light clamping and pressing fixtures where a compact footprint is critical.
Ideal for actuating small diverter gates or stops on conveyor lines, where the adjustable cushion protects the assembly from impact at speed.
For applications needing slightly more force in the same form factor, stepping up to the 50 mm bore (982 N at 0.5 MPa) is a common choice; stepping down to the 32 mm bore (402 N) saves space when full force is not required. The SC40X19S is a genuine AirTAC tie-rod cylinder—when replacing an existing unit, match the 40 mm bore, 19 mm stroke, PT1/4 port thread, built-in magnet, and basic (no bracket) mounting to ensure identical fit and sensor compatibility.
Quick checklist
At 0.5 MPa supply pressure the cylinder pushes with 628 N and pulls with 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 inside the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped onto the barrel for non-contact end-of-stroke detection.
