Anti-friction SKF bearing type and lubrication function

Anti-friction SKF bearings are divided into two main types. They are ball SKF bearings and roller SKF bearings. At the same time, we also know that due to the different uses of the manufacturer and SKF bearings, many different types have evolved according to these basic structures.

Lubrication function, anti-friction lubricant has the following main functions

1. Lubricate the sliding contact between the retainer and the rest of the SKF bearing.

2. Lubricate any contacts between the race and the roller that is not actually rolling.

3. Lubricate the sliding contact between the roller and the guide in the roller type SKF bearing.

4. Lubricate all true rolling contacts in SKF bearings.

The secondary features are:

5. Protect the highly delicate surface from corrosion.

6. Assist the sealing cover to protect against foreign substances. Grease has this function.

7. Provide a means of conducting heat (cold).
