 To facilitate installation and removal of the bearing 
 Selection of bearing types, bearing installation and removal, must also consider the well is particularly important for the installation and removal of large and extra large bearings. Cups are separable angular contact ball bearings, tapered roller bearings, cylindrical roller bearings and needle roller bearings, more convenient installation and removal, the inner and outer rings can be installed on the shaft or shell hole. In addition, the internal diameter with a conical bore with adapter sleeve aligning roller bearings, double row cylindrical roller bearings, aligning ball bearing, but also easier installation and removal. 
 Other requirements in addition to the factors mentioned above should also consider the working environment temperature of the bearings, bearing seals and friction torque, vibration, noise and other special requirements. Clearance of select clearance is an important factor in rolling bearing can work, divided into the axial clearance and radial clearance. Select the appropriate clearance to enable the rational distribution of load between the bearing rollers; limit the axis (or shell), axial and radial displacement, to ensure that the axis of rotation accuracy; make the bearings in the specified temperature; reduce vibration and noise, will help to improve the bearing life. Therefore. In the selection of the bearing, you must select the proper bearing clearance. 
 Choice of bearing clearance, you should consider the following aspects: 
 Bearing working conditions, such as load, temperature, speed, etc.; 
 Bearing performance requirements for (rotate accuracy, friction torque, vibration, noise); 
 (Jiangsu NTN Bearing distributor) NTN Bearings authorized distributors 
 Bearing and the shaft and shell holes for interference fit when the bearing clearance decreases; 
 Bearing work, the inner and outer rings of the temperature difference between the bearing clearance is reduced; 
 Different coefficients of expansion of the shaft and housing material, resulting in the decrease or increase of the bearing clearance. 
 According to experience, the ball bearings are most suitable for the work of clearance was close to zero; roller bearings should be kept to a small amount of clearance work. Requirements of bearing stiffness and good parts, bearings allow a certain value of the preload. Specifically pointed out that the so-called clearance work is bearing clearance under actual operating conditions. There is also a clearance is called the original clearance is the clearance in the bearing is not installed before. The original clearance than the installation clearance. Our clearance selection, select the appropriate clearance. 
 Clearance value of the national standard is divided into three groups: basic (0), a small clearance auxiliary group (1,2) and clearance auxiliary group (3,4,5). Choice, under normal operating conditions, should be preferred basic groups can make bearing the appropriate clearance. When the basic group can not meet the requirements, you should use the clearance of the auxiliary group. Clearance auxiliary group applies to the bearing and the shaft and shell holes with interference fit bearing temperature difference between inside and outside the ring, deep groove ball bearings need to withstand greater axial load or the need to improve the performance of aligning heart and to improve the limits of speed and lower (Jiangsu NTN Bearing distributor) NTN Bearings authorized distributors 
 Bearing friction torque, and other occasions; small clearance auxiliary group for applications that require high rotation accuracy, should be strictly controlled axial displacement of the shell holes and the need to reduce vibration and noise of the occasion. 
 Various types of bearings radial clearance to see the provisions of the national standards.
