RKB spherical roller bearings are self-aligning and consequently insensitive to the misalignment of the shaft relative to the housing and insensitive to shaft deflection or bending. The permissible value is up to 3.5° approximately depending on bearing series and size.
These bearings have two rows of rollers with sphered raceway in the outer ring and two inner ring raceways inclined at the proper angle to the bearing axis.
Used to operate in arduous conditions, leading in design, RKB spherical roller bearings can accommodate, in addition to high radial loads, axial loads acting in both directions.
The production range of RKB spherical roller bearings comprises open bearings, sealed bearings (suffix 2CZ1) and bearings for vibratory applications (suffix ROVS).
Besides, RKB offers spherical roller bearings customized for specific applications, as, for instance, bearings with split outer ring for higher permissible misalignment (suffix WOR) or with increased width dimension and consequent larger rollers for milling applications (project designation SRB) or for the support of the rolls of cold rolling Pilger mills for tubes.
