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 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 serves as a broad, stable mounting surface that enables direct bolted attachment to the machine structure, eliminating the need for additional adaptor plates or complex mounting hardware. The inner ring features internal gear teeth machined directly onto its inner circumference, positioning the drive pinion within the bearing envelope and providing natural protection for the gear teeth against external contamination and physical damage.
