The AirTAC Airtac SC40 Standard Cylinder SC40X1030S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1030mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X1030S is a double-acting pneumatic cylinder with a 40 mm bore and an extended 1030 mm stroke, built on AirTAC's compact tie-rod SC platform. At 0.5 MPa it delivers 628 N pushing force and 528 N pulling force, rising to 1130 N push at 0.9 MPa, making it suitable for long-reach material transfer or opening large guards where standard stroke lengths are insufficient.
This model includes the -S suffix for a built-in magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position sensing. It uses a 16 mm diameter piston rod with M12x1.25 male threads, PT1/4 ports, and adjustable air cushioning at both ends with a 21 mm cushion length. The total body length A is 142 mm, giving an extended length of approximately 1172 mm. Because the stroke exceeds the 1200 mm maximum standard stroke for bore 40, this is a non-standard, made-to-order configuration.

The 1030 mm stroke moves light to medium payloads across extended distances on conveyors or linear transfer stations, with magnetic sensors confirming end-of-travel.
Opens and closes oversized machine guarding or access panels where a stroke beyond 1 meter is required, using the adjustable cushion to soften the door's end-stop impact.
Directs product flow on wide sorting tables or chutes. The built-in magnet provides clean position feedback to the PLC without external brackets.
Choose the SC40 bore when 628 N at 0.5 MPa covers the load with a margin; if you need more force, step up to the SC50 which provides 982 N at the same pressure. For strokes of this length, the 16 mm rod is vulnerable to bending under side loads—always guide the load externally or consider a guided cylinder if lateral forces are present. When replacing an existing cylinder, match five points: 40 mm bore, 1030 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting configuration.
Quick checklist
At 0.5 MPa 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 means a magnet is built into the piston. You can mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly on the barrel tie-rods to detect piston position without adding external flags or brackets.
