Bearing damage Basics

Most of the imported bearing damage for many reasons, such as beyond the original estimate of the load, non-effective sealing, tight fit caused by too small bearing clearance and so on. Any one of these factors are factors that damage type has its unique and special damage will leave traces. Therefore, to view damaged shaft Precision bearing, in most cases you can find its probable causes.
Generally, a third of the bearing damage due to fatigue damage, arising out of the other one-third of poor lubrication, the other one-third of contaminants into the bearing arising out of improper handling or installation. However, these types of damage are not related with the industry. For example, half of the pulp and paper industry is due mostly to poor lubrication or bearing damage caused by pollution and not due to material fatigue caused byLubrication of bearings, in particular, the fatigue life of the rolling bearing and friction, wear, temperature, vibration, etc. have a major impact. Without proper lubrication, the bearings will not work. Bearing causes of damage showed that more than 40% of the backing bearings damage are related with poor lubrication. So, good lubrication for bearings is to reduce bearing friction and wear of effective measures.
Meanwhile, imports bearing lubrication and cooling, rust, sealing, ease the impact and other effects.
Bearing lubrication effects can be briefly described as follows
1, in the rolling surface contact with each other or the two form a film between the sliding surfaces of the second surface spaced from the contact surface to reduce friction and wear.
2, using oil lubrication, especially the use of circulating oil lubrication, oil mist lubrication and injection lubrication, the lubricant inside the bearing can take away most of frictional heat, serve as an effective heat sink.
3, using grease lubrication, be protected from external dust and other foreign matter from entering the bearing, and sealing effect.
4, the lubricant has a role to prevent metal corrosion.
