BNR/BAR/BTR/BER/BGR High-speed Thrust Angular Contact Ball Bearings

The BNR/BAR/BTR/BER/BGR series of high - speed thrust angular contact ball bearings are precision bearing products specifically designed for high - speed operating conditions. They possess unique structural designs and manufacturing processes to meet the stringent requirements of modern industrial equipment for high precision, high rotational speed, and high reliability.​
These bearings typically consist of an inner ring, an outer ring, rolling elements (high - precision steel balls), and a cage. The design of the cage is particularly crucial. Its function is to guide the uniform distribution of the steel balls, avoiding mutual collision and interference between the steel balls, thus ensuring the smooth operation of the bearing at high rotational speeds. For example, in the main shaft support of some aero - engines, the cage of the high - speed thrust angular contact ball bearing is made of lightweight and high - strength materials such as carbon fiber - reinforced composites, which greatly reduces its own weight and the influence of centrifugal force, thereby increasing the bearing's limiting rotational speed.
