 This is why many times the noise problem can be regarded as related to the vibration of the bearing application. Arising as a result of the loaded rolling element number of changes in excitation when a radial load to load on a bearing, load bearing rolling element number in the operation of a slight change in :2-2-3 ... This has led to the offset of the load direction. The resulting vibration is inevitable, but can be mitigated through the axial pre-load, load at all the rolling element (not applicable to FAG bearings, cylindrical roller bearings). 
 The wave of components in the case of secret cooperation between the FAG bearing ring and the bearing or drive shaft, the bearing ring may be compatible with the adjacent parts of the shape and deformation. If the deformation, in operation it may lead to vibration. Therefore, the bearing and the shaft is machined to the required tolerance is very important. 
 Local damage due to the operation or installation errors, the small part of the bearing raceway and rolling element may be damaged. In the operation of FAG bearings, rolling across the damaged parts can generate a specific vibration frequency. Frequency analysis to identify the damaged bearing components. The vibration behavior of applications in many applications, the bearing stiffness and the stiffness of the structure around the same. This feature to correctly select the bearings (including pre-load and clearance) and its configuration in the application, it is possible to reduce vibration applications. 
 FAG import bearing noise is a bearing itself, that is, bearing the inherent noise; another FAG import bearing capacity after noise has nothing to do with the FAG import bearing its own noise.

 INA bearings are generally composed of the inner ring, outer ring, rolling elements and cage. Various parts of the commonly used materials: high hardness and contact fatigue strength, good wear resistance and toughness of the material requirements of the rolling element and inner and outer rings. General manufacturing, commonly used materials including chromium alloy steel GCr15, GCr15SiMn, GCr6, GCr9 such as hardness up to HRC61-65 after heat treatment. Low carbon steel stamping cage made of high-speed bearings the use of non-ferrous metals such as brass or plastic cage. 

 Film INA bearing oil lubrication management is very important, can not be ignored. Lubrication management do a good job to prevent scratches or sintering of the friction of moving parts of INA bearings, gears, etc., to prevent and reduce wear and reduce friction, prevent equipment accidents, and improve the efficiency of production equipment; energy conservation, improve the effective energy utilization, increase economic benefits, the main tasks of lubrication management. 
 Lubrication Management is a professional technical and management should be set up full-time lubrication technology management, the development of lubrication management system, knowledge of lubrication technology training. 
 In the fuel tank capacity under the premise to keep the tank oil level, and often fill the lubricating oil to the fuel tank, the fuel tank of oil is always in a reasonable run the oil level, oil degassing, precipitation machine hybrid, the separation of water and reduce box oil temperature is beneficial to both.

 3, timing, positioning extraction run Petroleum samples for laboratory testing from the oil odor, chromaticity, changes in viscosity, water content, watershed performance, pollutant categories and content, anti-foam properties. Oil into the lubrication point more than 0.1% moisture content, mechanical wear is a sharp increase; more than 0.5 percent of the lubrication conditions will be very dangerous. Make detection records. 
 4, the analysis and comparison of each test record, forecast to develop improved or hedge to poor lubrication state. System oil level, oil, oil temperature, oil pressure control alarm and interlock to be safe and reliable, to eliminate lubrication accident. 
 This requires that the repairer to fully understand the INA Bearing the appropriate technical requirements, bearings and parts thereof in the structure, process and material characteristics, it would be difficult to ensure that the INA bearing repairs meet the requirements of the effect.
