How to avoid premature bearing failure

 In practical work due to poor lubrication or excessive work overload, excessive heat generated by friction and soften bearing steel, while causing the bearing to volume expansion, each extrusion pressure, when it reaches a certain level, the bearing will be locking the shaft on. Volume when the bearing overheats the holding bracket rolling gap becomes smaller, the stress concentration on the retainer, with the time, the cage will be broken, thereby accelerating the rate of bearing failure.
With the gap effect, the gap between the shaft and the shaft is too large, the relative movement between the two, one with the shaft section of the gap increasing excessive wear, leading to bearing failure: two of the bearing cracks, impact accuracy of movement. These causes of premature bearing failures are detrimental to our actual work, so study how to avoid premature bearing failure and prolong life is very practical value.
 2 How to avoid premature bearing failure
To prevent premature tapered bearing failure is the most effective way to avoid the above analysis of these factors contribute to a variety of factors and conditions: First, the bearing should be selected prior to use, taking into account the size of the noise, the size of the rigid, bearing radial fissures size, the size of rotational torque. Choice of lubricant, according to the bearing of the work environment, the type of lubricant in use produce different media noise. Such as grease lubrication oil lubrication noisy than the more well-lubricated bearings is to extend the life of the first condition. Use lubricated properly, can improve the accuracy of the smooth movement, but also can play a vibration absorbing buffer, reducing wear and tear effect. However, in the actual work which, bearing and lubrication quarter pollution is inevitable. The most common is the use of the protective cover can not completely prevent the relative movement of dust and stolen intrusion. However, the relative movement of inner and outer rings can not completely prevent contamination of the bearing, if the bearing is contaminated, the lubricant becomes the source of the noise,
