The UCFC series features a circular flange with a central pilot (locating boss). During installation, the pilot fits into a corresponding locating hole on the equipment panel, ensuring precise coaxial alignment. Secured by four bolts, this series is suitable for drive applications requiring high coaxiality and precise positioning. 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.
