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 supplied without gear teeth, featuring smooth outer surfaces that simplify handling and installation. The rollers are arranged with their axes alternating at 90-degree angles, creating a design that efficiently manages axial loads from both directions, radial loads, and tilting moments simultaneously. This crossed roller geometry establishes line contact with the raceways, delivering superior load-carrying capacity and enhanced rigidity compared to conventional ball bearings of equivalent dimensions.
The absence of gear teeth reduces manufacturing complexity, lowers production costs, and makes the bearing easier to handle during transportation and installation. Both rings incorporate mounting holes for secure bolted attachment to the machine structure.
