About This Bearing Unit

This product is a flange bearing unit, also known as a pillow block unit, which combines a bearing insert with a mounting housing. The UCF designation is a common nomenclature for these units: “UC” refers to the deep groove ball bearing insert, and “F” indicates the housing type, which is a square, four-bolt flange. The unit is secured to the shaft using two set screws in the extended inner ring, providing a simple and effective locking mechanism. The H suffix in the part number indicates a design for higher contamination resistance. This type of mounted unit is ideal for applications where the shaft needs to be supported at a right angle to the mounting surface, such as in conveyor systems, fans, and agricultural machinery.
