The AirTAC SC50 Standard Cylinder SC50X285S is a genuine double-acting standard air cylinder with a Ø50mm bore and 285mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X285S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (up to 1767 N at 0.9 MPa), built on a compact tie-rod body with a 150 mm body length A. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-stroke positioning tasks.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the barrel for non-contact position sensing. The 285 mm stroke is well within the 1200 mm maximum standard stroke for bore 50, making it a standard-configuration cylinder ready for immediate deployment.

The 285 mm stroke and 20 mm rod provide ample reach for medium-width conveyor diverter arms. The built-in magnet enables end-of-stroke sensing to confirm gate position before the next product arrives.
Apply 982 N of controlled clamping force at 0.5 MPa for CNC fixture or welding jig actuation. The adjustable cushion protects the fixture from impact shock at the end of the 285 mm travel.
Use the SC50X285S as a robust pallet stop or lift station actuator in material handling lines. Sensor feedback from the integrated magnet confirms retracted or extended status for interlock safety logic.
Select the SC50 bore when your application needs roughly 1000 N of force at standard plant pressure; step up to the SC63 for 1559 N at 0.5 MPa if the load margin is tight. For this 285 mm stroke, ensure the rod is not subjected to significant side loading—long unsupported rods can bend under lateral force; consider an external guide rail or switch to a guided cylinder if side loads are present. When replacing an existing unit, match five points: 50 mm bore, 285 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting style.
Quick checklist
At 0.7 MPa the push force is 1374 N and the pull force is 1155 N (the pull force is lower because the rod reduces the effective piston area on the retract side). At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 2000 N.
Yes. The -S suffix means this cylinder has a built-in magnetic piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods without any additional brackets or modifications.
