The AirTAC SC40 Standard Cylinder SC40X10H is a genuine double-acting standard air cylinder with a Ø40mm bore and 10mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X10H is a compact-stroke double-acting cylinder built for high-temperature environments, using Viton (FKM) seals to operate reliably from 0 to +150 °C. With a 40 mm bore and a short 10 mm stroke, it delivers 628 N of push force at 0.5 MPa, making it ideal for precise, short-travel clamping or ejection tasks in hot zones.
This model features a 16 mm diameter piston rod with an M12x1.25 thread and PT1/4 ports. The total extended body length is just 152 mm (142 mm body length A + 10 mm stroke), allowing it to fit into very tight machine envelopes. Its adjustable air cushion (21 mm length) decelerates the piston smoothly at end-of-stroke, protecting tooling even during high-speed short cycles.

The Viton seals handle 150°C ambient heat, allowing this 10 mm stroke cylinder to reliably eject parts from heated platen presses and molding tools.
Delivers 628 N of clamping force at 0.5 MPa for short-travel fixture holding in autoclaves, ovens, or soldering stations where standard seals would degrade.
The 10 mm stroke provides fast, repeatable diverter gate movement on hot-material conveyors in food processing or chemical plants.
For applications needing a short, high-temperature stroke, the SC40X10H is a direct fit. If you require more force, step up to the SC50 bore, which provides 982 N at 0.5 MPa. For longer strokes in the 40 mm bore, the standard range extends up to 1200 mm.
When replacing an existing cylinder, match five key points: 40 mm bore, 10 mm stroke, PT1/4 port thread, basic (no) mounting accessory, and the Viton seal designation (H). This is a tie-rod cylinder; it is not dimensionally interchangeable with ISO 15552 profile cylinders, so verify the body length A of 142 mm against your mounting space.
Quick checklist
At 0.7 MPa operating pressure, the push force is 879 N and the pull force is 528 N. The maximum theoretical push force at 0.9 MPa is 1130 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (A=142 mm) than a typical ISO 15552 profile cylinder. It is not dimensionally interchangeable. Only replace with another AirTAC SC40 tie-rod cylinder matching the same stroke, port, and seal type.
