Knowledge Of Bearing Lubrication

Lubrication has important influence on the fatigue life of tapered roller bearings, friction, abrasion, temperature and vibration, without normal lubrication, bearing cannot work. Analysis of the causes of bearing damage indicates that 40%% of the bearing damage is related to bad lubrication. Therefore, the good lubrication of bearings is an effective measure to reduce the friction and wear of bearings. In addition, bearing lubrication also has heat dissipation, anti-rust, sealing, mitigation and other impact of the role of bearing lubrication can be summarized as follows:

A. Formation of a layer of oil film between the two rolling surfaces or sliding surfaces in contact, separating the surfaces from each other, reducing friction and abrasion on the contact surfaces.

B. Oil lubrication, especially the use of circulating oil lubrication, oil mist lubrication and oil spray lubrication, lubricating oil can take away most of the internal friction heat of the bearings, play an effective role in heat dissipation.

C. Use of grease lubrication, can prevent external dust and other foreign bodies into the bearings, play a closed role.

D. Lubricants have the effect of preventing metal rust.

E. Extending the fatigue life of bearings.
