Thin section bearings and recommendations for the lubricant selection guides
2019-08-10
SILVERTHIN thin section bearing Lubrication guide:
CHG thin section bearing standard open (unsealed) bearings are shipped with only a light oil as a corrosion inhibitor. You must lubricate these bearings with the appropriate grease or oil for your application. Sealed bearings are shipped as standard practice with 20% - 30% fill of MilG-81322 grease.
Thin section bearings rely on ball and raceway surface lubrication. A thin film of oil or grease should be used. Be sure not to contaminate the lubricant used in the bearings.
As everybody knows that bearing’s Lubricants serve several important roles, especially for thin section bearings with a very thin wall. The functions of Lubricants are not only including protecting bearing surfaces from corrosion, the Lubricants are also reducing friction and preventing metal-to-metal contact between balls and raceway etc. Lack of lubrication or inadequate lubrication is the most common cause of bearing failure. This could cause a manufacturer to fully shut down and take a group of engineers to dig out this problem for a long time. That is why selection of suitable lubricants are very important. We recommend considering the proper grease as early as you could, even during the design stages.
As a professional grease and oil manufacturer, Klüber does not have a specific recommendation for thin section bearings. However, as a thin section bearing manufacturer, we tested different kind of greases from Klüber. The Klüberquiet BQH 72-102 showed excellent results during our tests in term of noise lowering capability. We will have test result and video published late on.
Klüberquiet BQH 72-102
Low noise thin section bearing grease for long-term lubrication
Klüberquiet BQ 72-72 - Lubricants - Klüber Lubrication
Klüberquiet BQH 72-102 is a synthetic high-temperature lubricating grease. Due to the careful selection of product components and the clean manufacturing environment, Klüberquiet BQH 72-102 is a thin section bearing grease with a particularly low noise level. Klüberquiet BQH 72-102 offers excellent performance characteristics thanks to a high-quality ester oil, a new polyurea thickener and special additives. It is special in that it combines high-temperature resistance and extreme purity.
For lubricant selection of thin section bearings, the final selection of proper greases is relied on your actual application. Speed, torque, temperature and designed life span etc. As a thin section bearing manufacturer, we will give you suitable suggestions please contact us at lyhg@lyhgbearing.com
