The importance of NTN bearing lubrication and NTN bearing lubrication role to introduce NTN bearing lubrication effect of NTN bearing lubrication, especially the fatigue life of rolling bearings and friction, wear, temperature rise, vibration and so on have important influence.
There is no normal lubrication, NTN bearing is unable to work.
And we have been analysis in the previous articles, NTN bearing damage reason shows that about 40% of the bearing damage is related to bad lubrication.
Therefore, good lubrication for NTN bearing is the effective measures to reduce the bearing friction and wear.
In addition, NTN bearing lubrication and cooling, a variety of action such as rust, seal, moderate impact.
The effect of NTN bearing lubrication can be briefly stated below.
The contact between two rolling or sliding surface formed between a layer of oil film separates two surface, reduce the friction and wear of contact surface.
b。
Using oil lubrication, especially the circulating oil lubrication, oil mist lubrication and oil lubrication, the bearing lubricating oil take most of the internal friction heat, effective heat dissipation effect.
c。
Using grease lubrication, can prevent external dust and other foreign body into the bearings, sealing effect.
d。
Lubricant function to prevent corrosion of metal.
e.
Extend the fatigue life of NTN bearing.
