UKF series adapter-mounted flange bearing unit consist of a deep groove ball bearing sealed on both sides and a spherical outside diameter mounted in a cast iron housing. It is designed for mounting onto bearing surfaces perpendicular to the shaft axis. The one-piece housing is made of gray cast iron for rigidity and vibration damping, and has a solid base for mounting stability. The double-sealed, deep-groove radial ball bearing insert in the housing is made of through-hardened chromium steel and is rated "light duty" for applications with moderate radial loads and light thrust or combination loads. The wide, extended inner ring on both sides of the bearing provides increased shaft support and reduced inner-ring tilt for smooth operation. 4 bolt flange bearings units are intended mostly for applications calling for simplicity of design and assembly.

This self-aligning bearing has a convex sphered outer surface that compensates for misalignment. Steel-reinforced molded rubber lip seals on both sides of the bearing retain lubricant applied at manufacture and help keep contaminants out. For added protection, flingers on the inner ring deflect contaminants away from the seals. The bearing locks onto the shaft with an adapter mount lock consisting of a split-sleeve tapered adapter, tabbed washer, and locknut (all included). They work together to create a 360-degree hold on the shaft without causing fretting between components. This lock type is suitable for applications requiring frequent adjustments or where the shaft oscillates or quickly reverses rotation. This bearing unit has a brass grease fitting on the housing outer surface for reapplying lubricant. 

Application

The pillow block bearings are suitable for use in industrial and commercial applications including conveyors, agricultural machinery, construction machinery, fans and blowers, and processing equipment, among many others.
