This bearing series consists of an inner ring, an outer ring with integral external gear teeth, and a single row of cylindrical rollers positioned in a crossed configuration between the raceways. The rollers are oriented with their axes alternating at 90-degree angles, creating a design that efficiently handles axial loads in both directions, radial loads, and tilting moments simultaneously. This crossed roller geometry establishes line contact with the raceways, delivering greater load-carrying capacity and enhanced rigidity compared to ball bearings of similar 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 overall part count. Both rings incorporate mounting holes for secure bolted attachment to the machine structure.
