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 arrangement between the raceways. The rollers are oriented with their axes alternating at 90-degree angles, creating a configuration that efficiently manages axial loads from both directions, radial loads, and tilting moments simultaneously. This crossed roller geometry provides line contact with the raceways, delivering 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 include mounting holes for secure bolted attachment to the machine structure.
