How to choose the type of bearing

Release time:

2023-05-18

There are also relevant introductions on how to choose the brand and type of bearings, but some common sense about bearings that are more biased, or are often ignored or ignored, often play a very important role in the use of bearings. Learn about it.
 
1. What is the life of the bearing?
 
For a single bearing, the number of revolutions of one ring relative to the other before fatigue expansion of one ring or rolling element material first occurs is called the bearing life. Due to differences in manufacturing accuracy, material homogeneity, etc., even bearings of the same material, same size and produced in the same batch work under exactly the same conditions, their lifespans will be very different.
 
2. What are the main failure modes of rolling bearings?
 
The main ones are: pitting corrosion, plastic deformation, abrasive wear, adhesive wear, rust, bearing burn, etc.
 
3. What is the basic rating life of the bearing?
 
According to the number of revolutions (in millions of revolutions) or the number of working hours before pitting damage occurs in 10% of the bearings in a set of bearings, and 90% of the bearings do not suffer from pitting damage, the life of the bearing is taken as the life of the bearing. It is called the basic rating life, and it is expressed as L10.
 
4. What is the basic dynamic load rating of the bearing?
 
When the basic rated life of the bearing is exactly one million revolutions, the load value that the bearing can bear is called the basic dynamic load rating of the bearing, which is represented by C. For radial bearings, it refers to pure radial load, which is represented by Cr; for thrust bearings, it refers to pure axial load, which is represented by Ca.
