The Ruland Six beam coupling represents a superior solution for light duty power transmission, ensuring seamless connections between servo motors and lead screws. Constructed from a single piece of 7075 aluminium, it boasts a unique design featuring two sets of three spiral cuts. This not only enhances its torque capacity but also minimises windup, making it ideal for applications that require precision. With operational speeds reaching up to 6,000 RPM, it successfully mitigates vibration and offers zero backlash, assuring consistent performance even under demanding conditions. Each coupling is rigorously machined in the USA, adhering to strict quality controls and high manufacturing standards, providing operators with reliability and peace of mind in their mechanical assemblies.

Zero-backlash functionality ensures accurate motion control

Superior torque capacities make it suitable for demanding applications

Metric hardware simplifies installation and usage in global settings

Manufactured from RoHS3 and REACH compliant materials for environmental assurance

Designed to handle angular and parallel misalignment effectively
