How to reduce the effect of temperature and vibrations on the life of INA bearings

INA bearings manufacturing generally after forging, heat treatment, machining, grinding and assembling multi-channel processes. Rationality, advanced processing technology, will also affect the stability of the bearings life. Which affect the quality of finished product bearings heat treatment and machining processes, often has a more direct relationship with bearings failures. On bearings surface modification layer of work in recent years studies have shown that close to grinding and surface quality of bearings.
, The effects of vibration on INA bearings.
In casual use, vibration damage to the bearings are very sensitive, indentation, rust, cracks, spalling, and wear are reflected in the measurement of bearings vibration. So, by using a special measuring bearings vibration (frequency Analyzer, etc) can measure the size of the vibration, through frequency cannot be inferred from specific situations of exception. Measured the numerical bearings conditions of use or different sensors such as installation location and therefore require prior to analysis and comparison of measurement values of each machine are determined criteria.

Second, the effects of temperature on the bearings.
Frequently expressed INA bearings at high temperature anomalies. High temperatures may also be harmful to the bearings lubricant. Sometimes bearings overheating can blame on the bearings lubricant. If bearings in more than 125 ℃ temperature long-term continuous transfers reduce bearings life. Cause of the high temperature bearings include: insufficient lubrication or excessive lubrication, lubricant. Contains impurities, excessive load, bearings loss rings, insufficient clearances, and oil have high friction and so on.
Therefore the continuity of INA bearings temperature monitoring is necessary, whether measured or other important parts of the bearings itself. If operating conditions do not change case, any temperature changes may have occurred at fault.
INA bearings periodic measurement of temperature using a thermometer, such as digital thermometers for precision measuring and bearings temperature degrees centigrade or Fahrenheit units display. Bearings of the importance to the effect that, when it is damaged, will cause the device to shut down, so this type of bearings should preferably install temperature scanners.
