The gearless single-row crossed roller slewing bearing is a precision rotational component developed for applications where high accuracy and rigidity are essential, yet integral gearing is not required. This design separates the bearing function from the drive system, allowing for greater flexibility in machine layout and drive selection while maintaining the superior load-handling characteristics of crossed roller technology.

This bearing series consists of an inner ring, an outer ring, and a single row of cylindrical rollers arranged in a crossed pattern between precision-ground raceways. Both rings are manufactured without gear teeth, resulting in a simple, clean profile that facilitates integration into various machine designs. 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 elimination of gear teeth simplifies the manufacturing process, reduces 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.
