This bearing series comprises an inner ring, an outer ring, and a single row of cylindrical rollers positioned in a crossed configuration between precision-ground raceways. Both rings are manufactured without gear teeth, resulting in a clean, streamlined profile. The rollers are oriented with their axes alternating at 90-degree angles, creating an arrangement that efficiently manages axial loads from both directions, radial loads, and tilting moments simultaneously. The crossed roller geometry provides line contact with the raceways, delivering greater load-carrying capacity and enhanced rigidity compared to ball bearings of similar dimensions.
The absence of gear teeth simplifies the ring geometry, reduces manufacturing complexity, and makes the bearing easier to handle during transportation and installation. Both rings incorporate mounting holes for secure bolted attachment to the machine structure.
