Tungsten Disulfide Used in Deep Groove Ball Bearing Lubrication

Tungsten disulfide has high application value in the lubrication of deep groove ball bearing with its excellent corrosion resistance. It provides maximum corrosion protection for this kind of part, which works under high temperature and heavy load. It is an efficient multifunctional material.

Deep groove ball bearing, which is the most widely used rolling bearing, is generally composed of outer ring, inner ring, steel ball and cage. It mainly bears radial load, and can also bear radial load and axial load at the same time. When it only bears radial load, the contact angle is zero. In the case of large radial clearance, deep groove ball bearing has the performance of angular contact bearing and can bear large axial load. Deep groove ball bearing is widely used in electric motor, automobile, motorcycle and many other fields, with its low friction resistance and high speed.

Although deep groove ball bearing is applicable to high-speed operation, it is prone to rust and corrosion. Here are the reasons as following as:

1. The equipment is poorly sealed, and water as well as dirt intrude.

2. The bearing is over rust prevention period and it is lack of maintenance.

3. The bearing surface is rough.

4. Bearing contact with corrosive chemical media by accident.

5. The quality of the bearing does not meet the requirements.

It can be seen that corrosion resistance is the main factor determining the service life of deep groove ball bearing. In order to improve the corrosion resistance of this kind of part, tungsten disulfide with good corrosion resistance can be applied. It can reduce the corrosion on bearing surface effectively. Moreover, this kind of material has excellent high temperature and extreme pressure resistance, so it works stably under heavy load, which is the working environment of deep groove ball bearing. From these points of view, tungsten disulfide has high application value in the lubrication of deep groove ball bearing.
