 In order to ensure higher with the effect of the shaft and seat hole and ASAHI spherical bearing to match the surface, the roughness should be as small as possible. 
 For the above measurement should be in ASAHI outside spherical bearings, cylindrical bore, and corresponding to the shaft and housing bore surface, near the assembly chamfer on both sides, respectively, made to indicate the maximum deviation of the direction of the two set of tags, so that the actual assembly, so that the maximum deviation of match between the two parties aligned the same position, so that after assembly, the two sides of the deviation can be partially offset. 
 Purpose to make two sets of directional signs is to compensate for the deviation can be taken into account, even if both ends of the bearing rotation accuracy is improved, and also allows the seat between the two bearing holes and both ends of the journal, the concentricity error be partly eliminated. With the surface of the implementation of surface hardening measures, such as sandblasting, with a diameter slightly larger than the precision plug column to insert the plug once bore, are beneficial to improve the fitting accuracy. 
 The ASAHI outer spherical bearing status is good or bad is directly related to rotating equipment condition, ASAHI is spherical bearing is widely used in the device. Especially in the continuity of large manufacturing enterprises, a large number of important parts used in large rotating equipment, so make the the ASAHI outer spherical bearing condition monitoring and fault diagnosis is an important link to improve equipment maintenance and management, actual production. Temporary practice and exploration, has accumulated a number of practical skills the ASAHI outside the sphere of the actual bearing fault diagnosis. 
 The main task of the NTN Bearing service life analysis is based on a lot of background material, data, and failure mode analysis, find out the cause of bearing failure, therefore, suggest improvements, to extend the service of bearing in order to avoid the sudden bearing the incidence of early failure .

 NTN Bearing parts work surface and center are large differences in the status, structure and performance requirements, NTN bearings and parts departments greater difference in the overall heat treatment are often not taken into account, the potential of the materials are not fully realized. Application of surface enhancement technology can not only solve the surface of the heart structure and needs of different department, and that further work surface to get some special attributes to meet the performance requirements under certain conditions, NTN Bearing surface. This modern scientific and technological development is very meaningful. 
 Is generally believed that more than 120 ° C temperature, high temperature working conditions will be considered at this time, ordinary NTN Bearing steel organizational change will occur and yield strength decreased gradually lose accuracy when the tempering temperature NTN Bearing NTN Bearing temperature exceeds materials, its hardness decreased, the working temperature exceeds 180 ° C, the hardness of a sharp decline in early fatigue and wear quickly. 
 Spherical plain bearings is one of the important parts of construction machinery, install the poor will affect their use of effects, and even cause the failure of the construction machinery and equipment. 
 If iron filings, burrs, dust and other foreign matter into the bearing, will enable the bearing running noise and vibration, and even damage the raceway and rolling element. So before installing the bearing, must ensure that the mounting surface and installation environment clean. 
 Extremely important impact on the operation and life of the joint bearing lubrication. Grease base oil, thickener and additives. Grease performance is mainly determined by the base oil. Generally low-viscosity base oil suitable for low temperature, high-speed; high viscosity suitable for high temperature, high load. 
 The thickener related lubricating properties, water resistance of the thickener to determine the water resistance of the grease. In principle, a different brand of grease can not be mixed, and even if the same kind of thickener of the grease will adversely affect each other additives different. Bearing surface is coated with anti-rust oil, must be carefully cleaned with clean gasoline or kerosene, and then coated with a clean and high quality or high-speed high-temperature grease before installation. Totally enclosed bearings do not need to clean the fuel.

 Spherical plain bearings installed, if not careful alignment, the alignment may lead to bearing subjected to a load, friction and vibration. These may accelerate fatigue and reduce the service life of bearings, and the period of use of other machine parts may be damaged. In addition, the increased vibration and friction may be greatly increased energy consumption and the risk of premature failure.
