6301 Bearings Lubrication:
The purpose and ways of lubrication
The lubrication is very important , which will directly affect the function of bearings in working conditions,Whether the lubricant isproperly used will have a great effect on the life of the bearings.
The main functions of the lubrication
1.Lubricate moving surface of all pats to reduce fiction and wearing
2.Reduce the heat caused by friction of bearings
3.Extend the life of bearings by oil covering on raceway
4.Prevent the bearings from dust and rust
The lubrication system of bearings includes grease and oil lubrication as follows:

6301 Bearing Consistent grease
The grease will not be supplied again for a long period once filed and its sealing device is very simple , so it is widely used.
Fill the sealing bearings with grease in advance or add it inside the outer covering , and supply more or replace it after a certain period. The grease can also be delivered by pipes to all parts of the machine if there are many parts to be lubricated.
The supplemental quantity of the grease
The supplemental quantity of grease is based on the structure and volume of the outer covering. In general, 1/3-1/2 of volume can beadded.
Watch out for the deterioration, aging and melting problems caused by the agitation heat when too much grease is added.
To prevent something coming into the low speed bearings, 2/3-1 of volume can be added.
