Kluberquiet BQ 72-72
Low-noise rolling bearing grease for long-term lubrication
Klüberquiet BQ 72-72, article number: 094008, e Edition 04.06, replaces edition 02.06
GATE-B/TB
Benefits for your application
— Long-term operation due to optimized wear protection ａnd smooth running
— Wide service temperature range allows a variety of applications
— Low costs due to long service life of grease at > 80 °C
— Particularly suitable for lifetime-lubricated deep groove ball bearings
Application
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).
Description
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 outstanding
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

characteristics at low temperatures.
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 compatibility with Klüberquiet®
BQ 72-72.
We can recommend suitable preservatives on
request.
Minimum shelf life
The minimum shelf life is approx. 24 months if
the product is stored in its unopened original
container in a dry, frost-free place.

* Service temperatures are guide values which depend on the lubricant＇s composition, the intended use ａnd the application method. Lubricants change their
consistency, apparent dynamic viscosity or viscosity depending on the mechano-dynamical loads, time, pressure ａnd temperature. These changes in product
characteristics may affect the function of a component.
** Speed factors are guide values which depend on the type ａnd size of the rolling bearing type ａnd the local operating conditions, which is why they have to be
confirmed in tests carried out by the user in each individual case.
