* 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
inpidual case.
Description
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.
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 tools 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.
Minimum shelf life
The minimum shelf life is approx. 12
months if the product is stored in the
closed original container in a dry
place.
