RKB spherical roller bearings

The spherical roller bearings (SRBs) manufactured by RKB are engineered to withstand high radial forces and moderate axial forces acting in both directions. RKB SRBs can dynamically accommodate misalignments due to shaft bending. They are produced with cylindrical or tapered bore, in open or sealed execution. Depending on application requirements, RKB Bainite Hardening Treatment (HB) and High Temperature Dimensional Stabilization (S) can be applied on bearing rings and rollers. Moreover, as for dimensions, RKB spherical roller bearings are manufactured according to ISO/ABMA/GOST speci cations. As a consequence, they are fully interchangeable with all the bearings that meet the relevant international
standards.
 
 

Tailor made solutions spherical roller bearings

Besides the main spherical roller bearing designs, RKB has developed new solutions according to speci c application requirements.
The special designs include SEALED SRBs, for smooth operation in contaminated environments, ROVSX type, expressly designed for vibratory equipment, WOR execution, suitable for gear output shaft of truck concrete mixers, and SPLIT bearings to make maintenance operations easier at hard-to-reach positions.
If duly applied, these special designs are cost effective for the customer, since they allow increased bearing life expectancy and reduced machine downtime
