Purpose of bearing lubrication:

The purpose of lubrication of rolling bearings is to reduce the internal friction and friction loss of bearings, prevent burning and sticking, and its lubricating effect is as follows.

⑴. Reduce friction and wear.

Prevent metal contact and reduce friction and wear in the mutual contact part of the bearing ring, rolling element and retainer.

(2) Prolong fatigue life.

The rolling fatigue life of the bearing is extended when the rolling contact surface is well lubricated during rotation. On the contrary, the oil viscosity is low, the lubricating oil film thickness is not good, it is shortened.

(3) Discharge friction heat and cooling

The circulating oil feeding method can use oil to remove heat caused by friction, or heat from the outside, and cool. Prevent the bearing from overheating and prevent the lubricating oil itself from aging.

(4) Other

It also has the effect of preventing foreign bodies from intruding into the bearing, or preventing rust and corrosion.

Lubrication method:

The lubrication method of bearing is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to choose the lubrication method suitable for the use conditions and the purpose 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, and the advantages and disadvantages of grease lubrication and oil lubrication are compared
