Double Universal Joints, Friction Bearing

Double friction bearing universal joints are designed for applications with a wide distance between shafts or applications in need of extreme angular misalignment accommodation up to 90°. They are comprised of two yokes, two blocks, and a center spacer joined by pins. Components are precision machined and ground to maintain tight tolerances, which allows for smooth operation with minimal backlash. Double universal joints are available in steel for high torque and stainless steel for increased corrosion resistance. Straight and step bore sizes including inch to metric are available from 3/16” to 1-1/2” and 5mm to 35mm. Boots can be added to protect the joints from contaminants in the operating environment. Boots can be packed with grease allowing for infinite life helping to reduce machine downtime.
