The Ruland Six beam coupling is a precision-engineered component designed to ensure efficient power transmission in light-duty applications. Its clamp-style mechanism securely joins shafts while accommodating modest misalignments, making it an ideal choice for coupling servo motors to lead screws. Manufactured from high-quality 7075 aluminium, this coupling delivers enhanced torque capacity without compromising on weight. Its zero-backlash design and balanced construction reduce vibrations even at high speeds of up to 6,000 RPM, ensuring reliable performance. The inclusion of Nypatch anti-vibration hardware adds to its robustness by providing optimal screw seating, preventing galling and ensuring that installations can be repeated without loss of holding power. With stringent manufacturing controls in place, it is crafted in the USA to meet both RoHS3 and REACH compliance, giving you peace of mind in its environmental impact.
