The RKS.22 series bearing 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 simultaneously support axial loads in both directions, radial loads, and tilting moments within a single, compact row of rolling elements.

The outer flange serves as the primary mounting surface, providing a broad, stable interface for bolted attachment to the machine structure. This integrated flange eliminates the need for additional adaptor plates or complex mounting brackets, simplifying the overall machine design. 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 internal gear arrangement provides protection for the gear teeth against external contamination and mechanical damage while enabling a more compact overall machine layout.
