This bearing series comprises 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 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 inner flange provides a generous, flat mounting surface that simplifies attachment to the machine structure. Rather than requiring separate adaptor plates or complex mounting brackets, the bearing can be bolted directly through the flange, reducing assembly time and component count. The outer ring features external gear teeth machined directly onto its circumference, allowing direct engagement with a pinion drive for efficient power transmission without the need for additional gear rings or coupling devices.
