Bearing balls are the component of a ball bearing that permit smooth, friction-free rotary motion. They are typically manufactured out of steel, but can also be made from other materials such as silicon nitride ceramic, plastic or even glass. Steel bearing balls are easily the most common ball material, with tens of millions produced annually.

The groove profile of ball-bearing raceway is of vital importance to ensure the bearing transmission accuracy. It is an attempt to apply electrolytic in-process dressing (ELID) groove grinding for the ball-bearing raceway finishing process. The wear rate of the grinding wheel is directly related to the profile accuracy of the bearing raceway. In order to maintain a high-forming accuracy, the ...

This paper presents a new dynamic modeling approach for spindle bearing system supported by both angular contact ball bearing (ACBB) and floating displacement bearing (FDB). First, a dynamic model of FDB is developed based on the discrete element method with each bearing component having six degrees-of-freedom (DOFs).

bearing can perform before incipient flaking occurs. This does not mean to say that the bearing cannot be used after then. Flaking is a relatively long, drawn-out process and makes its pres-ence known by increasing noise and vibration levels in the bearing. There-fore, as a rule, there is plenty of time to prepare for a change of bearing.
