Cylindrical roller bearing lubrication methods are grease lubrication and oil lubrication. In order to make the bearing perform well, first of all, it is necessary to choose a lubrication method suitable for the conditions and purposes of use. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing.
Purpose of lubrication :
The purpose of the rolling bearing lubrication is to reduce the internal friction and wear of the bearing and prevent burning and sticking. Its lubrication effect is as follows:
1) Reduce friction and wear
In the contact parts of the bearing ring, rolling element and cage, metal contact is prevented, and friction and wear are reduced.
2) Prolong fatigue life
The fatigue life of the rolling elements of the bearing is prolonged when the rolling contact surface is well lubricated during rotation. On the contrary, the oil viscosity is low, and the thickness of the lubricating oil film is not good, so it is shortened.
3) Exclude frictional heat and cooling
The cyclic oil supply method can use oil to discharge the heat generated by friction or the heat transmitted from the outside to play a cooling role. Prevent the bearing from overheating and prevent the lubricant from aging itself.
It also has the effect of preventing foreign matter from entering the bearing, or preventing rust and corrosion.
