The AirTAC Airtac SC40 Standard Cylinder SC40X900SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 900mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X900SH is a double-acting tie-rod cylinder with a 40 mm bore and 900 mm stroke, delivering a push force of 628 N at 0.5 MPa (1130 N at 0.9 MPa). The 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-stroke applications.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise position feedback. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it suitable for high-temperature or chemically aggressive environments.

The Viton seals and magnet sensor capability make this cylinder ideal for actuating gates or diverters in autoclaves, drying ovens, or sterilization equipment where ambient temperatures reach up to 150°C.
With a 900 mm stroke and 628 N of force at standard line pressure, it efficiently transfers lightweight components between distant conveyor stations or packaging lanes.
The integrated magnetic piston allows end-of-stroke sensors to confirm clamp engagement and release in automated assembly fixtures, ensuring cycle integrity in high-temperature curing processes.
For lower force requirements, consider stepping down to the 32 mm bore (402 N at 0.5 MPa). If you need higher thrust, the 50 mm bore provides 982 N at the same pressure. The 900 mm stroke is within the 1200 mm maximum standard stroke for the 40 mm bore.
For a stroke of this length, avoid side loads on the unsupported 16 mm rod. Use an external linear guide or a guided cylinder configuration to prevent rod bending and premature bearing wear. When replacing, match the 40 mm bore, 900 mm stroke, PT port thread, built-in magnet, and Viton seal material to ensure identical performance.
Quick checklist
At 0.5 MPa (standard factory air), 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 increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder. It is not dimensionally interchangeable. For a drop-in replacement, you must use another AirTAC SC40 tie-rod cylinder with matching bore, stroke, PT ports, magnet option, and Viton seals.
