The AirTAC SC50 Standard Cylinder SC50X80CB is a genuine double-acting standard air cylinder with a Ø50mm bore and 80mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X80CB is a 50 mm bore, 80 mm stroke tie-rod cylinder equipped with a rear double clevis (CB) mount for pivoting applications. It produces 982 N of push force at 0.5 MPa and 1767 N at 0.9 MPa, driven by a 20 mm diameter piston rod with M16x1.5 male threads.
This model features a 21 mm adjustable air cushion at each end to decelerate the piston smoothly. The CB mounting style, using bracket F-SC50CB, allows the cylinder body to pivot on a rear fork joint, making it ideal for applications where the cylinder must swing through an arc during actuation.

The rear clevis mount allows the cylinder to pivot as it opens and closes a hopper or trailer gate, handling the 982 N push force needed to move bulk material loads.
Drives a pivoting clamp arm in welding or assembly fixtures. The 80 mm stroke provides a compact clamping motion, and the CB mount simplifies linkage integration.
Operates a pivoting diverter gate on a conveyor line. The double clevis mount supports the swinging motion, while the adjustable cushion reduces end-of-stroke impact for consistent positioning.
For higher force requirements in the same mounting footprint, stepping up to the 63 mm bore SC63 series provides 1559 N of push force at 0.5 MPa. The SC50X80CB is a standard-stroke model (max standard stroke for bore 50 is 1200 mm) and uses PT1/4 ports with the default TPU seals rated for -20 to +70 °C. When replacing an existing unit, match the 50 mm bore, 80 mm stroke, PT port thread, and the CB rear double clevis mounting configuration to ensure dimensional and functional interchangeability.
Quick checklist
At 0.7 MPa operating pressure, the 50 mm bore SC cylinder generates 1374 N of push force on extension and 825 N of pull force on retraction. The maximum push force at 0.9 MPa is 1767 N.
Yes, provided the original unit is an SC tie-rod cylinder with a 50 mm bore, 80 mm stroke, PT1/4 ports, and a CB rear double clevis mount. This model does not include a magnet, so if your previous cylinder used magnetic sensors, you would need the -S suffix variant. Always verify the mounting bracket code (F-SC50CB) matches your existing setup.
