U-Joints

Discover a wide array of shaft couplings, chains and sprockets, belts and sheaves, and drive components.
U-joints connect two shafts to allow movement in any direction as they rotate and transmit mechanical power. Also called universal joints, U-joints come in many different types including ball and socket, cross and bearing, and pin and block. Ball and socket U-joints use a rotating ball in a socket to allow shaft rotation, while cross and bearing U-joints use cross-shaped joints with four bearings at each point. Pin and block U-joints consist of two block pieces connected by a pin to create an articulating joint and allow the two shafts to rotate.
