Everyone understands the necessity of lubrication for bearings, so do anti-friction bearings need to be lubricated? Today we take a look at the types of anti-friction bearings and their lubrication function with doubts.

Types of anti-friction bearings:

Anti-friction bearings are divided into 2 main types. They are steel ball bearings and roller bearings. In addition, we should also understand that because the special main uses of the manufacturers and their bearings are not the same, many different types have evolved according to this basic structure.

Lubrication function:

Anti-friction lubricants perform the following key functions

1. Lubricate the rolling contact between the retainer and other parts of the bearing.

2. Lubricate all contacts between the seat ring and the rolling parts that are not really turning.

3. Lubricate the rolling contact in the middle of the correct guide piece in the roller and roller bearing.

4. Lubricate all truly turning contacts in bearings.

The primary and secondary functions are:

5, maintain the high aspect ratio of fine surface is not etched.

6. Help the sealing cover defend against external chemicals. Grease has this function.

7, show a way of heat transfer (cold).
