The UCT series, also known as take-up bearing units, features guide slots on both sides of the housing, allowing for axial sliding along the rails of a matching frame. These units are primarily used in the tensioning systems of belt and chain conveyors; by adjusting the position of the bearing housing to alter the shaft center distance, the tension of the belt or chain can be regulated. The pillow block Bearings are essentially a variant of deep groove ball bearings; they are characterized by a spherical outer diameter surface on the outer ring, allowing them to fit into a corresponding concave spherical seat within the bearing housing to provide self-aligning capability. These bearings are primarily designed to accommodate combined radial and axial loads—with radial loads predominating—and are generally unsuitable for bearing axial loads in isolation.
