Klüberquiet BQH 72-102 High-purity rolling bearing grease 25kg bucket

High-purity rolling bearing grease for long-term 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 rolling 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.

Benefits for your application:

• Cost savings due to long service life of grease at > 80°C
• Smooth running, low noise
• Wide service temperature range allows a variety of applications
• Long bearing life due to excellent water resistance

Application:
In a wide variety of ball bearings operating under extreme thermal stress, Klüberquiet BQH 72-102 is used for long-term or lifetime lubrication. Such applications include ball bearings in electric motors, fans, air conditioners, generators and belt tensioners in cars, power tool as well as household appliances and office equipment.

Application notes:
The lubricant is applied by means of a spatula, brush, grease gun or grease cartridge. We recommend completely removing preservatives before applying the grease. Preservatives for permanent use should be checked for purity and chemical compatibility with Klüberquiet BQH 72-102. We can recommend suitable preservatives on request.
The possibility of a change in colour is inherent in this product concept. It has, however, no influence on product performance.
