The AirTAC SC50 Standard Cylinder SC50X65 is a genuine double-acting standard air cylinder with a Ø50mm bore and 65mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X65 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 65 mm stroke. At 0.5 MPa it generates 982 N pushing force and 825 N pulling force, making it a capable mid-range actuator for clamping, pressing, and light transfer tasks.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, and the total body length A is 150 mm, giving a compact footprint for machine builders.

Delivers controlled 982 N push force at 0.5 MPa for pressing bearings, bushings, or pins into housings on benchtop assembly fixtures.
Actuates a stop gate on a conveyor line. The 65 mm stroke provides enough travel to raise and lower a blade, while the adjustable cushion reduces impact noise.
Used in welding or machining jigs to clamp workpieces securely. The double-acting design provides powered retraction for quick part changeover.
Choose the SC50X65 when your application needs roughly 980 N of force at standard shop air. If you require more thrust, the SC63 bore steps up to 1559 N push at 0.5 MPa; for a lighter, more compact actuator, the SC40 delivers 628 N. Always match the replacement cylinder on all five key points: 50 mm bore, 65 mm stroke, PT port thread, basic (no bracket) mounting, and no magnet.
For strokes of 300 mm or longer, side loads become a concern—consider an external guide or a guided cylinder to protect the rod bearing. At 65 mm stroke, the rod is well-supported within the standard bearing length.
Quick checklist
At 0.5 MPa (5 bar) the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf (1961 N), but operation is limited to 0.15–1.0 MPa.
Yes, provided the original is an AirTAC SC tie-rod cylinder with a 50 mm bore, 65 mm stroke, PT1/4 ports, basic mounting (no bracket), and no magnet. The SC series is shorter than ISO 15552 cylinders, so it is not a direct replacement for those.
