The AirTAC SC50 Standard Cylinder SC50X66 is a genuine double-acting standard air cylinder with a Ø50mm bore and 66mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X66 is a double-acting tie-rod cylinder delivering a push force of 982 N at 0.5 MPa and up to 1767 N at 0.9 MPa operating pressure. Its 20 mm diameter piston rod and 66 mm stroke suit short linear movements in compact machinery where a non-standard stroke length is required.
With a body length A of 150 mm and a 21 mm adjustable air cushion, this genuine AirTAC actuator decelerates end-of-stroke loads smoothly. The PT1/4 port and M16x1.5 rod thread provide reliable pneumatic connections for factory automation tasks.

The 66 mm stroke and 20 mm rod provide a compact stop gate for small packages on a conveyor, applying controlled force to halt items without damage.
Delivers nearly 1800 N of clamping force at 0.9 MPa for holding workpieces during light machining or welding, fitting into tight fixture spaces.
Short, stiff stroke ejects parts from a die or mold. The adjustable cushion prevents impact shock when the rod extends fully at speed.
Choose the SC50X66 when your application needs roughly 1000 N of push force at standard shop air. If you need more force, the SC63 bore steps up to 1559 N at 0.5 MPa; for a lighter, faster actuator, the SC40 delivers 628 N. This 66 mm stroke is non-standard, so plan for a made-to-order lead time.
For a direct replacement, match five points: 50 mm bore, 66 mm stroke, PT1/4 port thread, basic mount (no brackets), and no magnet. This SC cylinder is not dimensionally interchangeable with ISO 15552 profiles—it is a shorter tie-rod design.
Quick checklist
At 0.5 MPa (approx. 73 psi), 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. The theoretical maximum force at 1.0 MPa is 200 kgf.
This basic model (SC50X66) ships without mounting accessories. You can order a rear single clevis (CA) or double clevis (CB) separately using part codes F-SC50CA or F-SC50CB, or specify the mounting suffix in the ordering code (e.g., SC50X66CA) for a factory-assembled unit.
