The AirTAC Airtac SC40 Standard Cylinder SC40X30SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 30mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X30SH is a double-acting single-rod tie-rod cylinder with a 40 mm bore and a 30 mm stroke, equipped with a built-in magnet and high-temperature Viton seals. At 0.5 MPa it generates 628 N pushing force, while the 16 mm diameter piston rod provides robust linear guidance for short-stroke clamping and positioning tasks.
With a body length A of 142 mm and a total extended length of approximately 172 mm, this compact actuator fits into tight automation envelopes. The -S suffix denotes the integrated magnet, allowing CMSG/DMSG/EMSG sensors to be mounted directly on the barrel for precise end-of-stroke sensing without external brackets. The H suffix upgrades the seal material to Viton (FKM), extending the operating temperature range to 0–150 °C for demanding thermal environments.

The Viton seals withstand 0–150 °C, making this cylinder ideal for clamping parts in heated assembly fixtures or welding jigs where standard seals would degrade.
Short 30 mm stroke opens and closes small autoclave or sterilizer doors, with sensor confirmation of the locked position via the built-in magnet.
Deploys a part stop on a conveyor carrying hot materials. The 628 N force at 0.5 MPa securely holds the part, while the magnet signals retraction.
Select the SC40X30SH when a 40 mm bore provides sufficient force for the load; the 628 N push at 0.5 MPa is a step up from the 32 mm bore's 402 N. For higher force requirements, stepping to the 50 mm bore yields 982 N at the same pressure. The 30 mm stroke is well within the 1200 mm maximum standard stroke for this bore. When replacing an existing cylinder, match five points: 40 mm bore, 30 mm stroke, PT port thread, the built-in magnet (-S), and the Viton seal material (H) to ensure identical thermal and sensing performance.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder provides 628 N of pushing force and 528 N of pulling force. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 1130 N.
It is a direct replacement only for an AirTAC SC series tie-rod cylinder of the same 40 mm bore, 30 mm stroke, PT ports, built-in magnet, and Viton seals. The SC is shorter than an ISO 15552 cylinder, so it is not dimensionally interchangeable with ISO 15552 profile types.
