This bearing series consists of an inner ring with an integral flange, an outer ring with external gear teeth, and a single row of steel balls arranged between precision-ground raceways. The four-point contact ball geometry allows the bearing to support axial loads in both directions, radial loads, and tilting moments simultaneously within a single, compact row of rolling elements.

The inner flange acts as both the primary mounting interface and a structural reinforcement, providing a wide, stable surface that distributes mounting loads evenly across the bearing. The outer ring is equipped with external gear teeth machined directly onto its outer diameter, enabling direct engagement with a drive pinion and eliminating the need for additional gear rings or complex transmission components. Both the flange and the outer ring are provided with mounting holes for straightforward bolted installation.
