Application of Tungsten Disulfide in Bearing Lubrication

Tungsten disulfide is an ideal material for bearing lubrication. It is suitable for the working environment of heavy load, and can form a dense protective film of tungsten trioxide on bearing surface under high temperature, so as to reduce the wear.

Bearing is an important part of mechanical equipment. However, it is prone to wear and damage due to the continuous operation under high temperature and heavy load. And among the many causes of bearing damage, insufficient or poor lubrication is the most fatal one.

There are four levels of bearing damage caused by lubrication problems.

1. Thermochromism

Thermochromism refers to the phenomenon of color change on part surface caused by temperature rise. Dry friction, which occurs because of insufficient or poor lubrication, makes the working temperature rise suddenly, resulting in the discoloration of bearing surface.

2. Metal Peeling Off

Under the working environment of high temperature and heavy load, the coating on bearing surface is prone to peel off, as there is no sufficient or good lubrication.

3. Thermal Damage Caused by Overheating of Roller End

Roller, a component bearing load during the running of bearing, is also the weakest part in the bearing. Moreover, the component affects the service life of the bearing. Thermal damage refers to the failure of parts due to thermal load. When there is insufficient or poor lubrication, the roller end is prone to overheating, resulting in the thermal damage of bearing.

4. Lock of Bearing

In severe cases, the whole bearing may be locked due to the insufficient or poor lubrication, which influences the operation of mechanical equipment directly.

How to reduce the bearing damage caused by insufficient or poor lubrication? Tungsten disulfide is an ideal material for bearing lubrication. It maintains good lubricating performance under the working environment of high temperature and heavy load. The dense film of tungsten trioxide formed by tungsten disulfide under high temperature has low friction coefficient. It can reduce the wear on bearing surface effectively and provide it maximum protection. Tungsten disulfide has high application value in bearing lubrication.
