The AirTAC Airtac SC40 Standard Cylinder SC40X585S is a genuine double-acting standard air cylinder with a Ø40mm bore and 585mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X585S is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa) from a 40 mm bore. With a 585 mm stroke and a 16 mm diameter piston rod, it suits medium-reach linear tasks where sensor feedback is required.
This model includes a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG reed or solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The body length A is 142 mm, giving a total extended length of approximately 727 mm. It uses PT1/4 ports and operates with filtered air from 0.15 to 1.0 MPa.

The 585 mm stroke moves components between conveyor lanes, while the built-in magnet lets CMSG sensors confirm end-of-stroke to the PLC before the next cycle starts.
Applies 628 N at 0.5 MPa to hold a workpiece during assembly. The sensor magnet enables a compact, externally mounted DMSG switch to detect the clamped position without adding bulk to the fixture.
Drives a diverter gate on a gravity chute. The 16 mm rod provides adequate stiffness for the gate load, and the -S magnet allows simple retrofitting of a reed switch for gate-open confirmation.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N push at 0.5 MPa. If a shorter, lighter cylinder suffices, the 32 mm bore SC32 offers 402 N at the same pressure. Always match bore, stroke, PT1/4 port thread, the built-in magnet (-S), and basic mounting when replacing an existing unit.
At 585 mm of stroke, the 16 mm rod is cantilevered significantly at full extension. Any side load will create a bending moment on the rod bearing; use an external linear guide or rod-alignment coupler to protect the rod and seals from premature wear.
Quick checklist
At the standard operating pressure of 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 in SC40X585S designates a built-in magnetic piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be mounted directly on the cylinder's tie-rod barrel for reliable, non-contact position sensing.
