PRODUCT

Full complement ball bearings BL series are ball-fitted bearings, which  capitalise on the space usually occupied by the ball retainer, as removing the retainer enables additional balls to be fitted. This increase in ball complement allows for significant increases in bearing capacity in either axial or radial directions, but relatively bearing operates at low speed.

 

The filler notch is ground into the ring so a dam is produced at the point of entry to the raceway. The dam, found on both rings, is calculated so that with the smallest ball and the maximum radial play, interference is maintained. After fitting the standard deep groove complement the notches are aligned and the balls pressed over the dams into the raceway.

 

The filler notch design bearing is primarily for use in applications where radial loads are dominant and the increased ball complements allow higher loads to be supported than in a standard caged deep groove bearing. Due to the introduction of a notch into each race on the same side, the filler notch design can be limited in its ability to carry axial load. For specific designs and applications the notch geometry can be optimised to carry an increased axial load in either one or both directions.

 

Application

The deep groove ball bearings are commonly used in automotive, wheels, electric motors, tools, appliances, transmissions, generators, conveyors and power tools.
