UCP = Two Bolt Pillow Blocks: use with radial loads acting in the direction of the support surface
UCFL = Two Bolt Flanges: Diamond or winged-shape with 2 holes for mounting. They are used when the bearing mounting surface is perpendicular to a shaft axis
UCF = Four Bolt Flanges: Square shape with 4 holes for mounting to accommodate higher loads than two-bolt flanges. They are used when the bearing mounting surface is perpendicular to a shaft axis
UCT = Take-up Bearings: T-shaped, commonly used to align conveyor tracks and maintain conveyor belt tension
