BRS Angular Contact Ball Bearings
BRS angular contact ball bearings have been designed to meet the increasingly demanding requirements of original equipment manufacturers. These bearings have a contact angle so that they can sustain significant axial loads in one direction together with radial loads. Furthermore, since an axial component is generated when a radial load is applied, these bearings are generally used in pairs, triplex sets, quadruplex sets, or multiplex sets. 

Preload and Rigidity
Regarding the rigidity of machine tool spindles, bearings can be considered as springs. When an axial load is applied to the spindle, axial displacement is determined by the axial rigidity of the fixed end bearings. Cylindrical roller bearings are generally used to support radial loads while angular contact ball bearings are used to sustain axial loads.

The bigger the contact angle of the angular contact ball bearings, the higher the axial rigidity. Bearings of the same bore size, which have more rolling elements (diameter series 0 or 9; or BNR10 or BNR19 series), have higher rigidity, even though the diameter or the rolling elements is smaller. 

Normally, preload is applied to bearings in order to increase rigidity of machine tool spindles. But excessively high  preload will result in flaking and possible seizure. Many users increase rigidity by using a combination of two or more angular contact ball bearings.
