The AirTAC SC50 Standard Cylinder SC50X63 is a genuine double-acting standard air cylinder with a Ø50mm bore and 63mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X63 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 63 mm stroke. It generates 982 N of push force and 825 N of pull force at 0.5 MPa, making it a strong mid-range actuator for short linear moves.
The 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration at end-of-stroke. With a compact body length A of 150 mm and PT1/4 ports, this cylinder fits easily into space-constrained automation cells.

The 63 mm stroke and 982 N push force are ideal for raising and lowering part stops or diverting gates on light to medium-duty conveyor lines.
Delivers controlled clamping force for jigs and fixtures in machining or assembly stations, with adjustable cushioning to reduce impact on tooling.
Powers short-throw flap folding mechanisms in packaging machinery, where the compact 150 mm body length simplifies machine layout.
For applications needing more force, stepping up to the 63 mm bore (SC63 series) provides 1559 N at 0.5 MPa. If space or force requirements are lower, the 40 mm bore delivers 628 N. The 63 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
When replacing this cylinder, match five key points: 50 mm bore, 63 mm stroke, PT1/4 port thread, basic mounting (no factory-fitted brackets), and no magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard operating pressure of 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 push force increases to 1767 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder. It is not dimensionally interchangeable. It should only replace another AirTAC SC tie-rod cylinder with the same bore, stroke, port, and mounting configuration.
