The AirTAC Airtac SC40 Standard Cylinder SC40X75SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X75SH is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa. Its 75 mm stroke suits compact clamping and ejector tasks, while the 16 mm diameter piston rod and 21 mm adjustable air cushion provide smooth end-of-stroke deceleration.
This variant includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, and Viton (FKM) seals (-H) that shift the operating temperature range to 0–150 °C. The body length A is 142 mm, giving a total extended length of approximately 217 mm.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
With Viton seals rated to 150 °C, this cylinder operates reliably in autoclave loaders, drying ovens, and heated press tooling where standard seals would degrade.
The built-in magnet allows CMSG/DMSG sensors to confirm clamp position. Ideal for automated fixture clamping in CNC machining where cycle verification is required.
With a speed range of 30-800 mm/s and 628 N of push force, this cylinder can rapidly eject lightweight parts from conveyor lines or sorting chutes.
For higher force at the same pressure, step up to the 50 mm bore SC50 series (982 N push at 0.5 MPa); for a lighter, more compact solution, the 32 mm bore SC32 offers 402 N. The 75 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
When replacing an existing cylinder, match five points: bore (40 mm), stroke (75 mm), port thread (PT1/4), mounting accessory (none, basic body), and magnet option (built-in magnet required). The SC is a tie-rod cylinder and is dimensionally shorter than ISO 15552 profiles—only another AirTAC SC40 of the same configuration is a direct drop-in replacement.
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.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors can be mounted directly on the barrel to detect piston position. The -H suffix specifies Viton seals for high-temperature environments up to 150 °C.
