 Regular inspection or replacement of parts, the need to disassemble the bearings. Usually the shaft and housing is almost always continue to use the bearings tend to want to continue using. Therefore, the structural design to take into account the demolition of the bearing, not to damage the bearings, shaft, bearing housing and other components, but also to prepare the appropriate removal tool. Demolition of static with the ferrule, only increase the tension in the ring, not by rolling the body to pull the ferrule. 

 Modern simulation technology with the extensive application of computer and rapid development. The specific practices a certain application conditions bearing the load direction, size, lubrication method, rotation speed, and environmental parameters, as well as bearing the main parameters entered into the computer through calculus to understand the life of the bearings may reach, in order to evaluate the bearing The design combination. This test method can significantly reduce the test time and reduce human and experimental funding can know in advance the application effect before the bearing is not manufactured, is a quick and hassle free trial. Foreign advanced bearing industrial companies, SKF, NTN bearing simulation test technology to reach the advanced level. 
 Development trends at home and abroad 
 At present, the bearing test at home and abroad, there are mainly four categories: friction and wear test, two test bench, the simulation test of the three laboratories (test site), four, the actual working conditions run test. Abroad These test methods are used, but the application purpose, for example, to develop a new product, first of all need to do friction and wear test. However, if the friction and wear in the form changed much, only the product size, and by changes in the carrier conditions, you just do bench, simulated or actual running test can be. Abroad, some of the key parts of the new product (such as wheel bearings, etc.) assessment is extremely strict, must be allowed to carry out supporting the use of the actual running test. Swedish SKF, NTN Japan, recent studies bearing simulation technology, only to replace the bench, simulation or experiment, to shorten product design time and accelerating product development progress, but from the actual operation of the gap. Now, the bearing industry in China has carried out the friction and wear test, one of Luoyang Bearing Research Institute; has been carried out bearing bench, the Luoyang Bearing Research Institute, Shanghai axis Institute, Hangzhou Bearing Test Center and Wafangdian, Harbin, 20 Yu Jiaguo bearing enterprises; can expand the simulation test, Luoyang Bearing Research Institute, Hangzhou Bearing Test Center and Los axis, Xiang-axis and other enterprises. And to the actual test, only bearing manufacturers in this regard requests to be carried out, such as wheel bearings and the cars of rail passenger wheel bearing host at supporting enterprise. In short, China is not yet widely in carrying out the simulation and the actual running test, should further expand the host range or scope of the actual working conditions, early on the agenda for the simulation test for adequate soft, hardware preparation.

 A. By NSK Bearings constructed type. 
 NSK Bearings (1) according to their direction or the public can bear the load that the contact angle, divided into: 
 2) for rolling bearings to withstand radial loads to the importance of radial bearings ---- nominal contact angle from 0-45. Nominal contact angle is divided into: radial contact bearings ---- nominal contact angle of 0 radial bearings: Angular contact bearings ---- nominal contact angle greater than 0-45 radial bearings. 
 3 thrust bearing ---- important for rolling bearing axial load, the nominal contact angle of greater than 45-90. Nominal contact angle is divided into: axial contact bearings ---- nominal contact angle 90 of the thrust bearings: angular contact thrust bearings ---- nominal contact angle greater than 45 but less than 90 of the thrust bearing. 
 NSK Bearings by rolling the number of columns, divided into: 
 1) Single row bearings ---- with a rolling element bearings; 
 2) double-row bearings ---- with two rolling element bearings; 
 3) multi-row bearings ---- with more than two rolling element bearings, such as three, four bearings. 
 NSK bearings according to their parts, divided into: 
 The ASAHI bearing an agent - Japan nsk-aligning ball bearings 
 1) bearing ---- have respectively components of the bearing; 
 2) is not, respectively, bearing ---- bearing in the final matching rings can not be any freedom of the respective bearings.
