The AirTAC Airtac SC40 Standard Cylinder SC40X15SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 15mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X15SH is a compact-stroke double-acting cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at the 0.9 MPa maximum operating pressure. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide smooth end-of-stroke deceleration in a short 142 mm body length.
This model includes 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 hot environments where standard TPU seals would degrade.

The Viton seals allow this cylinder to operate reliably in ambient temperatures up to 150°C, such as controlling a sliding gate near a furnace or drying oven. The built-in magnet provides open/closed confirmation via external sensors.
With a 15 mm stroke for precise, short-travel adhesive application and 628 N of force at standard line pressure, it drives a dispensing nozzle in packaging lines. The sensor confirms retraction before the next cycle.
Deploys a short, high-force push to position a heated platen. The adjustable cushion absorbs impact energy, while the magneto-reed sensor setup verifies the platen has fully retracted, ensuring operator safety.
For applications requiring slightly more force, the 50 mm bore SC50 series provides 982 N at 0.5 MPa. If a shorter overall length is critical, verify the 32 mm bore SC32 series offers 402 N. The 15 mm stroke is a standard length within the 40 mm bore's 1200 mm maximum.
To guarantee a correct replacement, match five points: 40 mm bore, 15 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the Viton seal material (-H). This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.7 MPa operating pressure, the theoretical push force is 879 N and the pull force on the rod side is 528 N. The maximum safe operating push force at 0.9 MPa is 1130 N.
No. The SC40X15SH is a double-acting cylinder and will not hold its position or a load if air pressure is exhausted or the directional valve is centered. The piston will drift or drop. For load-holding applications, you must add an external rod brake or a pilot-operated check valve.
