The AirTAC Airtac SC40 Standard Cylinder SC40X800H is a genuine double-acting standard air cylinder with a Ø40mm bore and 800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X800H is a double-acting pneumatic cylinder with a 40 mm bore and an 800 mm stroke, fitted with high-temperature Viton (FKM) seals that extend the operating range from 0 to +150 °C. This model delivers 628 N of push force and 528 N of pull force when supplied with 0.5 MPa air pressure, making it a reliable mid-range actuator for hot environments.
Its 16 mm diameter piston rod and PT1/4 port thread provide a robust connection, while the 21 mm adjustable air cushion at each end decelerates the piston smoothly to reduce end-of-stroke impact. The body length A is 142 mm, giving a total extended length of approximately 942 mm for this genuine AirTAC tie-rod cylinder.

Viton seals allow this 40mm bore cylinder to operate reliably in ovens, autoclaves, and near heat-sealing equipment where ambient temperatures reach up to 150°C.
With an 800 mm stroke and 628 N of push force, it's ideal for pusher arms or diverters on conveyor lines moving warm products or through heated wash-down zones.
Delivers consistent 528 N pull force for mold extraction or core-pulling in plastic thermoforming machines, resisting seal degradation from process heat.
Choose the SC40 bore for applications needing up to 628 N of force at 0.5 MPa. If your load requires more thrust, stepping up to the SC50 bore provides 982 N at the same pressure. For strokes of 800 mm, ensure the rod is guided externally if significant side loads are present, as the 16 mm rod can experience bending moments over long extensions. When replacing an existing unit, match the 40 mm bore, 800 mm stroke, PT1/4 port thread, and confirm the Viton seal material is required for your temperature range.
Quick checklist
At the standard 0.5 MPa operating pressure, the cylinder provides 628 Newtons of push force and 528 Newtons of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 Newtons.
No, the SC40X800H is a double-acting cylinder and will not hold its position if pressure is lost or the valve is centered. The piston will drift. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve in the circuit.
