Bearing clearance is an important parameter in the use of bearings. Too small working clearance will cause fever or even high temperature lock, too large working clearance will produce vibration, reduce the service life of bearings

What is bearing clearance?

Simply put, bearing clearance is the clearance (or interference) inside a single bearing or a system consisting of several bearings. Clearance can be divided into axial clearance and radial clearance, depending on bearing type and measurement method.

Why should bearing clearance be adjusted?

For example, cooking rice with too much or too little water will affect the taste of the rice. Similarly, if the bearing clearance is too large or too small, the working life of the bearing and even the stability of the whole equipment will be reduced.

The method of clearance adjustment is determined by the bearing type, which can be generally divided into non-adjustable clearance bearings and adjustable bearings.

The clearance of the non-adjustable bearing refers to that after the bearing leaves the factory, the clearance of the bearing is determined. The deep groove ball bearing, self-aligning bearing and cylindrical bearing that we are familiar with all belong to this category.

Clearance adjustable bearings refer to the relative axial position of the bearing raceway can be moved to obtain the required clearance, which belongs to tapered bearings and angular contact ball bearings and some thrust bearings.
