The UCF pillow block mounted bearing series has four bolt holes, and a set screw lock is designed for mounting onto bearing surfaces parallel to the shaft axis, such as conveyor belts. This ready-to-mount unit has solid base cast iron housing, chrome steel bearings, and is designed for efficient operation at a wide range of speeds. This one-piece pillow block housing allows for a stationary outer ring and rotating inner ring. Insert bearing maintains the separation between moving parts to reduce rotational friction, and to support radial and axial loads. The bearing is secured to the shaft with set screws to prevent slippage. This mounted bearing is used in food and beverage manufacturing, textile industry and many other industrial manufacturing.
