We called this design is UC pillow block bearing, The hardened steel balls exhibit a high degree of “roundness” and the races are highly polished to accommodate a smooth ride at a wide range of speeds. UC Series bearing are the most used in the mounted ball bearing units.

flange bearing units have the special ability to self-align inside the housing because of the spherical shape of the outer diameter of the bearing insert and the concave shape of the inner diameter of the housing into which it fits.

The housings are made primarily of gray cast iron, and stamped steel. Plastic and cast steel, Gray cast iron is the most popular choice for bearing units because of its optimal characteristics of vibration absorption, high strength, and excellent heat dissipation.
