Let's have a preliminary understanding of the bearing:
 

1. Control structure diagram understanding retention groove ball bearings, angular contact ball bearings, ball bearings, cylindrical roller bearings, spherical roller bearings, needle roller bearings and tapered roller bearings for radial bearings; vertebral thrust ball bearing, cylindrical roller bearings, thrust needle roller bearings, force angular contact ball bearings, spherical roller thrust bearings and tapered roller thrust bearing for measures of force bearing.
 

2. Rolling bearing outside diameter size is divided into miniature bearings, miniature bearings, small and medium-sized bearings, large bearing, bearing large and large bearing; linear motion rolling bearing points for linear transport power ball bearings, linear motion bearings, line and ball movement guideway, blind linear motion of needle roller bearing guide and linear motion guideway five categories.
 

3 bearings are divided into radial joint bearing, angular contact joint bearing, thrust bearing and rod end bearing. In addition, it can also be divided into general purpose bearings and special bearing. Special bearing according to the application of the host and can be divided into automobile bearings, railway bearings, machine tool bearings, rolling mill bearings, motor bearings, etc.. Such as the use of performance can be divided into high speed bearings, high temperature bearing, bearing, etc..
 

If we are able to grasp the above problems, so we have more understanding of the bearing in the work more.
