The AirTAC SC50 Standard Cylinder SC50X630S is a genuine double-acting standard air cylinder with a Ø50mm bore and 630mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X630S is a double-acting single-rod pneumatic cylinder delivering 982 N push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore, 20 mm diameter piston rod and M16x1.5 rod thread, this model is built for mid-range automation tasks requiring a 630 mm stroke.
This variant includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the tie-rod barrel for piston position detection. The adjustable air cushion at each end is 21 mm long, and the total extended body length is approximately 780 mm (150 mm body length A + 630 mm stroke).

Pushes or diverts boxes and totes on a conveyor line, with the 630 mm stroke covering wide belt sections.
Applies 982 N of clamping force at 0.5 MPa for workpiece fixturing on a machining centre or welding jig.
Actuates a pusher plate to eject parts from a gravity feed rack into a pick station.
The SC50X630S suits applications where the 982 N push force at 0.5 MPa is sufficient but a step to the 63 mm bore (1559 N at 0.5 MPa) might be considered for higher force margins. For this 630 mm stroke, ensure the load is guided externally if side forces are present; the unsupported 20 mm rod can deflect under lateral loads. When replacing, match bore, stroke, PT port thread, the -S magnet option, and the basic mounting configuration.
Quick checklist
At 0.5 MPa air pressure, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N.
Yes, the -S suffix indicates a built-in magnet. You can clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the barrel to detect piston position.
