The AirTAC SC50 Standard Cylinder SC50X80N is a genuine double-acting standard air cylinder with a Ø50mm bore and 80mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X80N is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, featuring a 50 mm bore and an 80 mm standard stroke. It generates a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod with M16x1.5 threads.
This model is configured with NBR (nitrile) seals, offering reliable performance within the standard -20 to +70 °C temperature range. The compact tie-rod body has a length A of 150 mm, providing a total extended length of 230 mm, and includes PT1/4 pneumatic ports with an adjustable air cushion of 21 mm for smooth end-of-stroke deceleration.

Provides the 982 N force needed at standard line pressure to reliably stop or divert packages on a conveyor system, with the 80 mm stroke offering a compact actuation distance.
Delivers a controlled 1767 N clamping force at 0.9 MPa for holding workpieces during machining or assembly, with the NBR seals handling oily shop air environments.
Ideal for automating quarter-turn valves or small linear diverters, where the 20 mm rod and 80 mm stroke provide a robust, compact solution for repetitive open/close cycles.
For applications requiring slightly less force, consider stepping down to the 40 mm bore SC40 series, which provides 628 N of push force at 0.5 MPa. If higher force is needed, the 63 mm bore SC63 series offers 1559 N at the same pressure. This 80 mm stroke model is well within the standard range, but for strokes exceeding 300 mm, ensure the rod is protected from side loads with an external guide.
When replacing this cylinder, match five key specifications: the 50 mm bore, 80 mm stroke, PT1/4 port thread, NBR seal material, and the basic mounting configuration. This ensures dimensional and performance interchangeability with an existing AirTAC SC tie-rod unit.
Quick checklist
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the theoretical push force reaches 1767 N. The maximum theoretical force at 1.0 MPa is 200 kgf.
No. The 'N' suffix designates NBR seals, which are rated for a standard temperature range of -20 to +70 °C. For high-temperature applications up to 150 °C, you should select the 'H' suffix variant, which uses Viton (FKM) seals, such as the SC50X80H model.
