RBC Thin Section Ball Bearings
RBC thin section ball bearings are engineered to solve a variety of design problems that cannot be solved with conventional ball bearings.
Duplex Pairs
Duplex bearings are a pair of angular contact thin section ball bearings specially ground for use as a matched set.
There are three basic mounting methods to accommodate different loading requirements:
A duplexed pair can be used to provide accurate shaft location, to increase capacity or to increase stiffness of the bearing assembly. A duplex pair of thin section ball bearings is ground so that when mounting using recommended fits, there will be no internal clearance in the bearings.
Back to Back (DB) B-Type
Face to Face (DF) F-Type
Tandem (DT) T-Type
Axial Preloading
Standard duplex bearings are ground so that there will be a light axial preload induced on the bearing at nominal conditions. In some applications increased bearing stiffness may be required. In these cases the duplex grinding can be done such that a heavier axial load is induced in the mounted bearing. This load can be increased or decreased to meet the requirements of a particular application.
