The AirTAC Airtac SC40 Standard Cylinder SC40X300SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 300mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X300SH is a double-acting pneumatic cylinder engineered for high-temperature applications, featuring a 40 mm bore and a 300 mm stroke. With Viton (FKM) seals, this model operates reliably in ambient temperatures from 0 to +150 °C, making it suitable for autoclaves, foundries, and drying equipment. It generates a theoretical push force of 628 N at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa.
This cylinder is built on a durable tie-rod construction with a 16 mm diameter piston rod and an M12x1.25 rod thread for secure tooling attachment. The -S suffix indicates a built-in magnet, allowing direct mounting of CMSG or DMSG sensors along the barrel for precise, non-contact position feedback. The total extended body length for this 300 mm stroke configuration is approximately 442 mm, providing a compact yet powerful actuation solution.

The Viton seals enable this cylinder to operate in ambient temperatures up to 150°C, making it ideal for actuating dampers, gates, or clamps inside industrial ovens, kilns, and autoclave systems.
With the built-in magnet, CMSG/DMSG sensors clamp directly to the tie-rod barrel for end-of-stroke or mid-stroke detection, ensuring precise, repeatable control in automated pick-and-place or pressing stations.
Delivers reliable 628 N push force for actuating hot-melt glue heads or sealing jaws on packaging lines, where the machine's radiant heat would degrade standard polyurethane seals.
Choose the SC40X300SH when your application demands a balance of force and speed in a high-temperature environment. If the 628 N push force at 0.5 MPa is insufficient, stepping up to the SC50 series provides a significant boost to 982 N. For applications with lower thermal requirements, the standard TPU seal variant (SC40X300S) operates in a -20 to +70 °C range.
For this 300 mm stroke, carefully evaluate the potential for side loading on the 16 mm rod. In applications where the load is not guided, the extended rod is susceptible to bending and premature bearing wear. To ensure long service life, install an external guide rail or rod alignment coupler to absorb transverse forces, preventing them from acting directly on the piston rod and seals.
Quick checklist
At the standard 0.5 MPa operating pressure, the theoretical 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.
Yes, the 'S' in the model code SC40X300SH designates a built-in magnetic piston. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel for contactless position sensing without any additional brackets.
