This bearing series consists of an outer ring with an integral flange, an inner ring with internal 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 outer flange serves as both the mounting interface and a structural reinforcement, providing a broad, flat surface that distributes mounting loads evenly and ensures accurate alignment during installation. The inner ring features internal gear teeth machined directly onto its inner surface, enabling the drive pinion to be housed within the bearing envelope. This arrangement provides natural protection for the gear teeth against external elements while reducing the overall machine footprint.
