Lubrication On Fatigue Life And Friction Of Rolling Bearings

- Dec 07, 2017 -

Lubrication on the rolling bearing fatigue life and friction, wear, temperature rise, vibration and other important effects, no normal lubrication, bearings can not work. The analysis of the bearing damage indicates that 40% or so of the bearing damage is related to poor lubrication. Therefore, good lubrication of bearings is an effective measure to reduce friction and wear of bearings. In addition, bearing lubrication and cooling, anti-rust, sealing, mitigation impact and other functions, bearing lubrication can be briefly described as follows:

A. Prolong the fatigue life of the bearing.

B. Oil lubrication, especially the use of cyclic oil lubrication, oil mist lubrication and fuel injection lubrication, lubricating oil can take away most of the internal friction heat, play an effective cooling effect.

C. The use of grease lubrication, can prevent external foreign bodies such as dust into the bearing, play a closed role.

D. Lubricants have the effect of preventing metal corrosion.

E. Formation of an oil film separating the two surfaces between the two rolling or sliding surfaces in contact with each other to reduce friction and wear on the contact surface.
