Select grease according to operating temperatureThe working temperature of the lubricating part is an important basis for selecting grease. The typical component that uses grease is a rolling bearing. As far as the relationship between bearing temperature and grease life is concerned, every 10-15 ° C increase in bearing temperature reduces the grease life by about 1/2. Generally, the temperature of the outer ring of the bearing is about 15 ° C lower than the temperature of the inner ring. The temperature of the bearings working at low and med...

Choose grease according to purposeWhen selecting a grease, the purpose of the grease should be clearly defined. According to the role played by grease, grease can be roughly divided into three categories: friction reduction, protection, and sealing. It depends on which part of the grease needs to be applied, which one is the main role of the grease. grease. As antifriction grease, the range of resistance to high and low temperature, the limit of resistance to rotation speed, and the load should be considered. As a protective gre...
