Integrated bearings utilize a single, integrated structure, combining rolling elements, shaft, housing, and other components into a single bearing assembly. It consists of an integrated inner ring, an integrated outer ring, multiple sets of rolling elements, a cage, and seals. A single bearing can simultaneously withstand radial and axial loads, eliminating the need for multiple bearings to be paired and installed. This results in a compact structure, simplified installation and positioning, and the elimination of accumulated precision errors from assembling multiple parts.
