Everybody knows how to select lubricants (bearing lubricant selection) for thin section bearings is critical for bearing's life. Bearing’s Lubricants serve several important roles, especially for thin section bearings with a very thin wall. The lubricants protect bearing surfaces from corrosion, reduce friction, prevent 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 entirely shut down and take a group of engineers to dig out this problem for a long time. That is why the bearing lubrication selection is essential. We recommend considering the proper grease as early as possible, even during the design stages.

HGT thin section bearing standard open (unsealed) bearings are shipped with only a light oil as a corrosion protector. We 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. Through many years of production experience in thin section bearings, we have tested a lot of greases made by different manufacturers. Every brand has its characters; now, we use Klüberas an example.

As a professional grease and oil manufacturer, Klüber does not recommend greases for thin section bearings. However, as a thin section bearing manufacturer, we tested greases from Klüber. The Klüberquiet BQH 72-102 showed excellent results regarding noise lowering capability during our tests.  The test result and video upon request.

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 thanks to a high-quality ester oil, a new polyurea thickener, and special additives. It is unique in that it combines high-temperature resistance and extreme purity.

For the bearing lubrication selection of thin section bearings, the final selection of proper greases relies on your actual application, according to parameters which like speed, torque, temperature, and designed life span, etc.; our team will give our suggestion and test it at our manufacturer to confirm our recommendation.
