According to the ISO classification standard, precision bearings are divided into: P0, P6, P5, P4, P2. The grade increases in turn, among which P0 is ordinary precision, and other grades are precision grade. Of course, different classification standards a
Falling off of bearing seal ring means that the seal ring falls out of the seal groove. The firmness of the seal ring after assembly is verified by drop test. The reason for the seal ring falling off is that the interference between the seal ring flange a
The types, types and sizes of rolling bearings are various. In order to make the mechanical device to play the expected performance, it is very important to choose the most suitable bearing.In order to select bearings, many reasons need to be analyzed. Th
The characteristic of lubricated bearing is that the friction is linear contact and the friction coefficient is large. It is generally used in low speed and heavy load machinery.1、 Selection of lubricant for sliding bearingThe main factors to be considere
The choice of bearing is also related to the direction of load. Pure radial load can choose deep groove ball bearing or cylindrical roller bearing. The thrust ball bearing is only suitable for bearing a proper amount of pure axial load. One way thrust bal
As we all know, the lubrication of motor bearing will directly affect the life of bearing and the service life of motor. It is very important to add grease (oil) to the motor bearing correctly and regularly. Today, let's give you a brief introduction of t
The specific reasons of bearing natural wear are as follows:The tiny peaks and valleys on the surface of the friction layer squeeze each other, which makes the brittle surface layer gradually fall off and wear.① Oxidation wear. The tiny peaks and valleys
Test run inspection of bearing.In order to check whether the bearing is installed correctly, the test run inspection should be carried out after the installation.For small machinery, the rotating parts can be turned by hand first to check the rotation fle
The influence of cleanliness on bearing performance.1. Influence on bearing lifeThe cleanliness of bearings has a great influence on the service life of bearings. Special tests have been carried out on bearings, and the results show that the difference is
Methods of removing rust on bearing surfaceFrequent use of bearings, if not regularly cleaned, the oil will reduce its service life. Some readers recommend the following methods to share with you.The bearing hardened by soft dry oil or antirust paste shou
