The AirTAC SC50 Standard Cylinder SC50X35 is a genuine double-acting standard air cylinder with a Ø50mm bore and 35mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X35 is a compact-stroke member of the AirTAC SC tie-rod cylinder family, delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. Its 35 mm stroke suits short-throw clamping, ejecting, or stopping actions where space is tight but a solid 20 mm diameter piston rod is needed.
With a body length A of 150 mm, this double-acting cylinder uses filtered air to power both extend and retract strokes. The adjustable air cushion at each end decelerates the piston smoothly, and the standard PT1/4 ports make plumbing straightforward in new builds or direct replacements for existing AirTAC SC50 installations.

The 35 mm stroke and 1767 N force at 0.9 MPa make it ideal for pneumatic toggle clamps and workpiece holding fixtures in machining centres.
Deploy the SC50X35 as a compact end-stop or diverter gate on conveyor lines, where a quick, repeatable 35 mm linear motion is required.
Use the controlled 982 N push at 0.5 MPa for light press-fit insertion of bearings, bushings, or pins in automated assembly cells.
Choose the SC50 bore when your application needs roughly 1000 N of force at typical shop air. If you need less force and a lighter assembly, step down to the SC40 (628 N push at 0.5 MPa); for higher force in the same footprint class, the SC63 delivers 1559 N. For strokes above 300 mm, add an external guide or switch to a guided cylinder to protect the rod bearing from side loads.
To replace an existing cylinder, match five points: 50 mm bore, 35 mm stroke, PT1/4 port thread, the basic (no bracket) mounting style, and confirm whether a magnet is needed—this SC50X35 is the non-magnet version.
Quick checklist
At 0.7 MPa the SC50X35 produces 1374 N of push force. The pull force on the retract stroke at the same pressure is 825 N, accounting for the 20 mm rod area.
This specific SC50X35 model does not include the -S magnet option, so CMSG/DMSG/EMSG sensors cannot be used directly. To use barrel-mounted sensors, order the SC50X35-S variant which has a built-in magnet.
