This bearing series comprises an inner ring, an outer ring with integral external gear teeth, and a single row of cylindrical rollers arranged in a crossed configuration between precision-ground raceways. The rollers are oriented with their axes alternating at 90-degree angles, creating a design that efficiently manages axial loads in both directions, radial loads, and tilting moments simultaneously. This crossed roller geometry establishes line contact with the raceways, providing greater load-carrying capacity and enhanced rigidity compared to ball bearings of equivalent dimensions.

The external gear is formed directly on the outer ring surface, enabling direct engagement with a drive pinion without requiring separate gear components. This integration simplifies the drive system and reduces the overall part count. Both rings incorporate mounting holes for secure bolted attachment to the machine structure.
