The choice of bearing products involves many different aspects. One of them is the bearing clearance. It is the interval that exists between the balls and the inner and outer races of the bearing. Clearance is important for a bearing as it can have an effect on bearing life and other factors related to the cohesiveness of the bearing.
The bearing clearance of a ball bearing is a measure of the geometrical space between three parts, i.e. outer ring, ball, and inner ring. Different clearances may have different functions and features. It is very important for you to choose the proper bearing products. Therefore, before selecting your bearings, it's important to have an understanding of what kind of clearances you are working with. Many things are related with clearance choices.
There are different kinds of clearances. As to the ball bearing clearance, it is necessary to make a distinction between axial and radial. Generally, the axial clearance refers to the space between ball and races parallel to the bearing access, while the radial clearance refers to the give between ball and races perpendicular to the bearing axis.
