The AirTAC Airtac SC40 Standard Cylinder SC40X240SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 240mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X240SH is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa) from its 40 mm bore. The 240 mm stroke is well within the 1200 mm maximum standard stroke for this bore, making it a readily available configuration.
This variant includes a built-in magnet (S) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, enabling precise end-of-stroke or mid-stroke position feedback. The H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C for hot or chemically aggressive environments. It uses a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Viton seals allow reliable operation in ovens, autoclaves, or foundry equipment where ambient temperatures reach up to 150°C.
The built-in magnet enables easy sensor attachment for position verification in automated sorting gates or diverter arms on conveyor lines.
Provides 1130 N of thrust at 0.9 MPa for consistent clamping force in light-duty assembly jigs or hot-stamping fixtures.
For applications requiring slightly more force, stepping up to the 50 mm bore (SC50) provides 982 N at 0.5 MPa. If space is a constraint, the 32 mm bore (SC32) offers 402 N. The SC40X240SH is a direct replacement only for another AirTAC SC40 tie-rod cylinder matching the 240 mm stroke, PT1/4 ports, built-in magnet, and Viton seals.
At 240 mm stroke, the 16 mm rod is adequately supported for axial loads, but any significant side loading requires an external guide or a guided cylinder to prevent rod bending and premature seal wear.
Quick checklist
At the standard 0.5 MPa operating pressure, the cylinder provides 628 N pushing force and 528 N pulling force. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 1130 N.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC40 cylinder with the same stroke, port thread, magnet option, and seal material.
