The AirTAC Airtac SC40 Standard Cylinder SC40X150SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 150mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X150SH is a double-acting pneumatic cylinder with a 40 mm bore and 150 mm stroke, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable end-of-stroke deceleration for medium-duty linear tasks.
This model features a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise position feedback. The -H suffix specifies Viton (FKM) seals, shifting the operating temperature range to 0–150 °C, making it suitable for high-temperature or chemically aggressive environments where standard TPU seals would degrade.

Actuating sterilisation cabinet doors and clamps where the 0–150 °C Viton seals withstand repeated high-temperature washdown cycles without hardening or leaking.
Operating diverter gates on hot-material conveyors in foundries or bakeries, using the built-in magnet to confirm gate position with CMSG sensors.
Pressing and holding components during high-temperature curing or bonding processes, where the 628 N push force at 0.5 MPa provides consistent clamping pressure.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push force at 0.5 MPa. If a shorter, lighter cylinder is sufficient, the 32 mm bore SC32 series offers 402 N at the same pressure. Always match the replacement cylinder across five key points: bore, stroke, PT port thread, the built-in magnet option (-S), and the Viton seal material (-H) for high-temperature compatibility. The SC series is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard operating pressure of 0.5 MPa, the SC40X150SH generates 628 N of push force and 528 N of pull force. 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.
This model uses Viton (FKM) seals, indicated by the -H suffix, and is rated for continuous operation from 0 to 150 °C. Standard TPU-sealed SC cylinders are limited to -20 to 70 °C. The Viton seal material also offers better resistance to synthetic oils and certain chemicals compared to TPU or NBR.
