This bearing series comprises an inner ring with integral internal teeth, an outer ring, and three rows of cylindrical rollers arranged in precision-machined raceways. The three rows are specifically allocated to handle distinct load components: one row manages axial loads in one direction, a second row handles axial loads in the opposite direction, and the third row supports radial loads. This dedicated load path design ensures that each roller row can be independently sized and configured for its specific function, enabling efficient load transmission and balanced performance under complex loading conditions.

The internal gear is machined directly on the inner ring, positioning the drive pinion within the bearing envelope. This configuration provides several practical benefits: the gear teeth are safeguarded from external contamination, debris, and physical impact; the overall footprint of the rotating assembly is minimized; and the machine design can be streamlined for improved efficiency. Both rings are drilled with mounting holes for secure bolted attachment to the machine structure.
