Klüberquiet BQ 72-72 is made up of an ester oil, a polyurea thickener and special additives. These components have been combined such that Klüberquiet BQ 72-72 offers many advantages for the lubrication of rolling bearings:
- extremely low-noise operation shown on special test rigs, e.g. SKF BeQuiet+
- long bearing life due to optimized wear protection and a thermally stable, synthetic grease
- good compatibility with elastomers (data available on request)
- wide service temperature range and good low-temperature performance
Klüberquiet® BQ 72-72 is highly suitable for bearings where long service life is required in combination with especially low-noise operation. Such applications include rolling bearings in electric motors, fans, air conditioners, generators and belt tighteners in cars, electric household appliances and office equipment. The low-noise characteristics of this rolling bearing grease have been confirmed in various tests performed on special noise test rigs. Tests according to the SKF-BeQuiet+ method showed that Klüberquiet® BQ 72-72 can be classified as noise class GN 3. Grease service life tests were conducted on SKF-ROF and FAG-FE9 rolling bearing testers according to DIN 51 821. The results showed long service lives at high temperatures (see product data).
