The Ruland Six beam coupling is designed for precision applications. With its robust construction from high-grade aluminum, it is engineered to provide superior torque capacity and excellent performance. This coupling aligns two shafts effectively, facilitating seamless power transmission while minimising backlashes. Featuring a balanced design, it significantly reduces vibrations, making it ideal for high-speed operations. It prides itself on being lightweight yet strong, ensuring lower inertia and an ability to withstand demanding conditions. Whether you are coupling a servo motor to a lead screw or working on light-duty power transmission applications, this coupling is tailored to meet your needs with utmost precision.
Balanced construction minimises vibration at high speeds, catering to up to 6,000 RPM
Constructed from 7075 aluminium for optimal strength-to-weight ratio
Fulfils RoHS3 and REACH compliance for environmentally conscious operations
Designed to accommodate angular, parallel, and axial misalignment
Comes with M5 screws to secure the coupling efficiently
Manufactured in the USA under strict quality control measures
