How to choose the right bearing? These 7 factors are indispensable

How to choose bearings correctly? These 7 factors are indispensable. How to choose bearings correctly? When choosing bearings, we should base on several important parameters: bearing load, bearing speed, self-aligning requirements, allowed space, bearing installation and removal, tolerance grade and price. Bearings mainly play the role of supporting and reducing friction in machinery, so the accuracy and noise of bearings are directly related to the use and life of machinery.

Generally speaking, the steps of choosing bearings may be summarized as follows:

1. According to the working conditions of bearings, including load direction and type, speed, lubrication method, coaxiality requirements, positioning or non-positioning, installation and maintenance environment, ambient temperature, etc., select the basic type, tolerance grade and clearance of bearings;

2. According to the working conditions, stress conditions and life requirements of bearings, determine the bearing model through calculation, or select the bearing model according to the use requirements, and then check the life;

3. Check the rated load and limit speed of the selected bearing.

The main considerations for choosing bearings are limit speed and load capacity, and other factors help to determine the final plan of bearing type, structure, size, tolerance grade and clearance requirements.

7 factors we should consider when choosing bearings

Various types of rolling bearings have different characteristics and are suitable for different use cases of various machines. Generally, thrust bearings and angular contact bearings are used when bearing thrust loads; ball bearings are usually used for high-speed applications, and roller bearings are used when bearing heavy radial loads.
