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 with spacers arranged between precision-ground raceways. The four-point contact ball geometry enables 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 provides a wide, flat mounting surface that facilitates direct bolted attachment to the machine structure, eliminating the need for complex adaptor plates or additional mounting brackets. The inner ring features internal gear teeth machined directly onto its inner circumference, allowing the drive pinion to be positioned within the bearing envelope. This arrangement ensures that the gear teeth are protected from external contamination, debris, and physical impact, reducing wear and extending service life.
