Manufacture of bearings generally through forging, heat treatment, turning, grinding and assembly of multi-channel processing. The reasonableness of the processing technology, advanced, will also affect the stability of the bearing life. Which affect the quality of the finished bearing heat treatment and grinding processes, often with bearing failure have a more direct relationship. In recent years, the working surface of the bearing metamorphic layer studies show that the quality of the grinding process and is closely related to the bearing surface.
A, the impact of vibration on the bearing.
In normal use, the vibration of the bearing damage is quite sensitive, peeling, dents, rust, cracks, wear, etc. will be in the bearing vibration measurement reflected. So, by using a special bearing vibration measurements (frequency analyzer, etc.) to measure the size of the vibration, frequency points can not be inferred abnormal circumstances. The measured values due to the conditions of use or the bearing sensor mounting location is different, so each machine needs prior to analysis and comparison of the measured values determined criteria.

B, the temperature of the bearing.
Often expressed with high temperature bearings in unusual circumstances. Temperature is harmful to the bearing lubricant. Sometimes bearing overheating can be attributed to the bearing lubricant. If the bearing temperature over 125 ℃ even move to reduce long bearing life. Caused by high bearing the following reasons: lack of lubrication or excessive lubrication, lubricant. Containing impurities, the load is too large, the bearing ring damage, lack of space, and produce high-friction seals and so on.
Therefore, continuous monitoring of bearing temperature is necessary, whether it is measuring the bearing itself, or other important parts. If the operating conditions remain unchanged in the case of temperature change can be said of any fault has occurred.
Bearing temperature measured by means of a regular thermometer, such as digital thermometers, bearing temperature can be accurately measured and determined in accordance ℃ or Fahrenheit units. The importance of bearing, which means when it is damaged, can cause equipment downtime, so this type of bearing temperature probe should preferably be installed.
