The Ruland Clamp style six beam coupling is designed for precision performance in light duty power transmission applications. This coupling seamlessly connects shafts with 8mm bores, ensuring a zero-backlash operation that enhances efficiency and reliability. Crafted from high-quality 7075 aluminium, it promises both lightweight construction and low inertia, making it exceptionally suitable for high-speed operations. With a compact design featuring a 31.8mm outer diameter and a length of 44.5mm, it is engineered for minimal vibration even at speeds up to 6,000 RPM. The advanced machining process incorporates two sets of spiral cuts, offering superior torque capacity and reducing windup. Ruland's proprietary spiral coupling also includes Nypatch anti-vibration hardware, ensuring maximum screw performance in dynamic settings. Manufactured in the USA under stringent controls, this product adheres to the highest standards of quality and compliance.
