The AirTAC Airtac SC40 Standard Cylinder SC40X800SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X800SH is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa), built for long 800 mm linear strokes in high-temperature environments. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration, while the built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for precise position feedback.
Equipped with Viton (FKM) seals, this cylinder operates reliably from 0 to +150 °C, making it suitable for autoclaves, foundries, and drying lines where standard seals would degrade. The SC40 body length A is 142 mm, giving a total extended length of approximately 942 mm. As a genuine AirTAC tie-rod cylinder, it offers a compact, serviceable design that is shorter than an equivalent ISO 15552 profile cylinder.

With Viton seals rated to 150 °C, this 800 mm stroke cylinder operates safely in autoclave door mechanisms, drying ovens, and hot press tooling where standard seals would fail.
The 800 mm stroke and 628 N push force at 0.5 MPa efficiently transfer parts across wide conveyor gaps or push heavy totes onto palletizers in packaging lines.
The built-in magnet (-S) pairs with CMSG/DMSG sensors to confirm end-of-stroke in automated assembly, ensuring the 800 mm extension is reached before the next cycle begins.
For applications needing more force, the SC50 bore provides 982 N at 0.5 MPa; for lighter, faster cycling, the SC32 offers 402 N. At 800 mm stroke, the 16 mm rod is susceptible to bending under side load—always guide the load externally or use a guided cylinder if radial forces are present. When replacing an existing unit, match five points: 40 mm bore, 800 mm stroke, PT port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting configuration. The Viton seal (-H) must also be matched if the application runs above 70 °C.
Quick checklist
At 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.
No, the SC40 is a double-acting cylinder and does not lock or hold position when pressure is exhausted or the valve is centred—the piston will drift. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod brake.
