The importance of bearing grease

Many people don’t know how to choose the correct bearing grease when buying bearing grease? From what aspects can we buy bearing grease so that the bearings can get better lubrication effect? The editor below summarizes some questions from customers, hoping to help everyone better understand the selection method of bearing grease.

How to better buy bearing grease? It is necessary to start from the basic characteristics of bearing grease, which are mainly reflected in the following three aspects:

1. Base oil type & viscosity

The viscosity of the base oil affects the formation of the lubricating film. The most common base oils are mineral oil and synthetic oil. The former is the lowest-cost base oil, and its production process and cost are far simpler and cheaper than synthetic oil.

2. Thickener

Thickener is an important component of grease. The thickener is dispersed in the base oil and forms the structural skeleton of the grease, allowing the base oil to be adsorbed and fixed in the structural skeleton. The water resistance and heat resistance of grease are mainly determined by the thickener.

3. Additives

All greases contain additives. However, some additives improve the performance of the base oil itself (antioxidants, viscosity adjusters, detergents, etc.), while others act on bearings and metal surfaces (such as anti-wear additives, corrosion inhibitors, friction reducers).
