The AirTAC SC50 Standard Cylinder SC50X700H is a genuine double-acting standard air cylinder with a Ø50mm bore and 700mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X700H is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 700 mm stroke suits medium-reach material handling, and the 20 mm diameter piston rod provides good column strength for axial loads.
This model is equipped with Viton (FKM) seals, shifting the operating temperature range to 0 to +150 °C for reliable performance in high-heat environments. The tie-rod construction keeps the 150 mm body length compact, and the adjustable air cushion at each end decelerates the piston smoothly.

Viton seals allow this cylinder to operate in ambient temperatures up to 150°C, making it suitable for autoclave doors, drying ovens, or foundry equipment where standard seals would fail.
With 982 N of push force and a 700 mm stroke, it efficiently transfers components between conveyor lanes or indexing stations in packaging and assembly lines.
The FKM seals resist degradation near heated platens or welding heads, providing consistent clamping and positioning force for hot-melt assembly or plastic welding jigs.
For higher force, step up to the 63 mm bore (1559 N at 0.5 MPa); for a lighter, more compact actuator, the 40 mm bore offers 628 N. At 700 mm stroke, ensure the load is guided externally if side forces are present—an unsupported 20 mm rod can bend under lateral load. When replacing, match bore, 700 mm stroke, PT port thread, Viton seal, and basic mount. This cylinder is not dimensionally interchangeable with ISO 15552 profiles.
Quick checklist
At 0.7 MPa operating pressure, the theoretical push force is 1374 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N.
No. The SC50X700H is a double-acting cylinder and will not hold position when air pressure is exhausted or lost. The adjustable air cushion only decelerates the piston at stroke end; it is not a locking device. For load holding, add a pilot-operated check valve or an external rod brake.
