The importance of lubricating oil to milling machines

Jun 03, 2019

How to choose grease lubrication has a very important impact on the operation and life of the bearing. Here is a brief overview of the general principles for selecting grease. Grease is made of base oil, thickener and additives. The grease performance of different types and different grades varies greatly. The allowable rotation limit is different. Be careful when selecting. The performance of the grease is primarily 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. The thickener is also related to the lubricating properties, and the water resistance of the thickener determines the water resistance of the grease. In principle, the different greases of the brand cannot be mixed, and even the grease of the same thickener may have a bad influence on each other due to the different additives.

 

When lubricating the bearing, the more grease is applied, the better. When lubricating the bearing, the more grease is applied, the better. This is a common misconception. Excessive grease in the bearing and bearing chambers will cause excessive agitation of the grease, resulting in extremely high temperatures. www.chamferingmachinechina.com
