The AirTAC Airtac SC40 Standard Cylinder SC40X700S is a genuine double-acting standard air cylinder with a Ø40mm bore and 700mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X700S 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 700 mm stroke, it features a 16 mm diameter piston rod and M12x1.25 rod thread for secure tooling attachment.
This model includes the -S suffix, equipping the cylinder with a built-in magnet. This allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable, non-contact position feedback. The standard TPU seals provide a -20 to +70 °C operating range, and the PT1/4 pneumatic ports ensure straightforward connection to common air circuits.

The 700 mm stroke and 16 mm rod provide ample reach for diverting packages or parts on wide conveyor lines, with sensors confirming gate open/close status.
Delivers consistent 628 N force at 0.5 MPa to apply pressure-sensitive labels onto products, with the magnetic piston enabling cycle counting via barrel-mounted sensors.
Ideal for light-duty lifting and lowering of totes in pick-and-place modules, where the adjustable air cushion decelerates the load smoothly at stroke ends.
For applications requiring more force, consider stepping up to the 50 mm bore SC50 series, which provides 982 N of push at 0.5 MPa. If a shorter overall length is acceptable and force requirements are lower, the 32 mm bore offers 402 N. At a 700 mm stroke, ensure the rod is protected from side loading; consider an external guide or linear rail to prevent bending moments on the 16 mm rod, which can damage the rod bearing and seals. As a genuine AirTAC SC replacement, match the 40 mm bore, 700 mm stroke, PT1/4 port thread, and the -S magnet option for sensor compatibility.
Quick checklist
At 0.5 MPa, the push force is 628 N and pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
Yes, the -S suffix indicates a built-in magnet, making it compatible with AirTAC CMSG, DMSG, or EMSG sensors that clamp directly onto the tie-rod barrel for end-of-stroke or mid-stroke position sensing.
