The Ruland Top-tier set screw style four beam coupling, engineered for exceptional performance in dynamic applications. Its unique construction from a single piece of 303 stainless steel showcases superior torque capacity and enhanced longevity. With an outer diameter of 22.2 mm and a length of 27.0 mm, this coupling also maintains a balanced design that effectively reduces vibrations at elevated speeds, supporting operations up to 6,000 RPM. The innovative spiral cut design accommodates greater body sizes compared to traditional single beam couplings and ensures zero backlash functionality. Additionally, it is crafted under stringent manufacturing controls in Marlborough, MA, to deliver consistent quality and reliability.
Designed for high torque capacity and minimal windup
Constructed from RoHS3 and REACH compliant materials
Incorporates rigorous testing standards for maximum torque capabilities
