 In general, the steps to select the bearing may be summarized as: bearing working conditions (including the load direction and the type of load, speed, lubrication methods, concentricity requirements, location or non-positioning, installation and maintenance of the environment, ambient temperature, etc.), select basic types of bearings, tolerance grades and clearance; bearing working conditions and forces of life requirements, the rated load calculation to determine the bearing model, or according to the requirements of the selected bearing model, and then checking the life; checking the selected bearing and the limit speed. Select bearing the major considerations is the limit speed, requiring the Dacron life and load capacity, and other factors help determine the bearing type, structure, size and tolerance grades and clearance work to seek final plan. Type select various types of rolling bearings have different characteristics, applicable to a variety of different machinery usage. The choice of bearing type, usually the following factors should be considered. Selected to withstand the thrust loads under normal circumstances: the thrust bearing, angular contact bearings, and high-speed applications typically use ball bearings to withstand heavy radial loads, the selection of roller bearings. In short, the selection of officers from different manufacturers, many bearing products, choose the appropriate type. 
 Bearing share of the machinery space and location 
 In mechanical design, generally determine the size of the shaft, then select rolling bearings, according to the size of the shaft. Is usually small axis of the choice of ball bearings, shaft optional roller bearings. However, when the diameter of the bearing in the machine direction is restricted, the choice of needle roller bearings, light weight and ultra-light series ball or roller bearings; When the bearing is limited in the axial position of the machine, the choice of narrow or special narrow series of ball or roller bearings.

 Size, direction and nature of the bearing suffered load 
 The load is the most important factor in the selection of bearings. Roller bearing to withstand heavier loads and ball bearings to withstand a lighter or medium load, carburizing steel or bainite hardening of the bearing can withstand shock and vibration loads. Subject to pure radial loads in the load direction of action, may make use of deep groove ball bearings, cylindrical roller bearings or needle bearings. Withstand the smaller pure axial load, thrust ball bearings can be used; withstand a larger pure axial load, the choice of thrust roller bearings. When bearing radial and axial load, generally used in angular contact ball bearings or tapered roller bearings. 
 Bearing aligning performance 
 When the centerline of the shaft and the bearing centerline, angle error, or due to the shaft two bearing spacing of the large axis of rigidity in smaller, vulnerable force bent or tilted, the choice of the tune with a good aligning properties of aligning ball or spherical roller bearings, as well as outside the ball bearings. Such bearing axis is slightly inclined or curved, can maintain the work properly. Bearings Self-aligning performance is good or bad, rather than allow the misalignment, the misalignment value is bigger and better aligning performance. Various types of bearings allow the misalignment shown in Table 1
