Miniature bearing grease selection

2022-09-07

Since grease is made of base oil, thickener and additives, the performance of different kinds and different grades of the same kind of grease varies greatly and the allowed rotational limit is different, so it is important to pay attention when choosing.

The general principles of grease selection.

The performance of grease is mainly determined by the base oil. Generally low viscosity base oil is suitable for low temperature and high speed; high viscosity is suitable for high temperature and high load. Thickener is also related to the lubrication performance, and the water resistance of thickener determines the water resistance of grease. In principle, different brands of grease cannot be mixed, and even the grease with the same thickener can bring bad influence to each other because of different additives.
