The AirTAC Airtac SC40 Standard Cylinder SC40X40SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 40mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X40SH is a compact tie-rod cylinder delivering 628 N of push force at 0.5 MPa, making it a strong performer for its 40 mm bore class. Its 40 mm stroke suits short, repetitive clamping, ejecting, or sorting tasks where space is tight but reliable double-acting motion is essential.
This model features a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150°C for demanding hot environments. It uses a 16 mm diameter rod with M12x1.25 threads and standard PT1/4 ports.

The Viton seals handle 0–150°C, making this cylinder perfect for clamping fixtures in heated platen presses or thermoforming tools where standard seals would degrade.
With its 40 mm stroke and sensor-ready magnet, it reliably stops hot parts on conveyors exiting ovens or dryers, providing position feedback in elevated temperatures.
Suitable for short-stroke actuation inside autoclaves or sterilisation equipment, where the FKM seals resist steam and high heat, and the magnetic piston allows external sensor monitoring.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push force at 0.5 MPa. This SC40X40SH is ideal where the 32 mm bore's 402 N is insufficient but a 50 mm cylinder is too large. When replacing, match the 40 mm bore, 40 mm stroke, PT1/4 port thread, the built-in magnet, and the Viton seal material to ensure full compatibility with existing sensor and temperature requirements.
Quick checklist
At the standard 0.5 MPa operating pressure, 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.
Yes. The -S suffix indicates a built-in magnet, allowing you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's sensor slots for contactless position sensing.
