* 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 mechanodynamical
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.
Description
PETAMO GHY 443 and
PETAMO GHY 441 are special
lubricating greases based on ester
oil and polyurea thickener. They are
used for long-term and lifetime
lubrication of rolling and plain
bearings subject to high loads and
elevated temperatures. PETAMO
GHY 441 and 433 incorporate high
viscosity base oils with excellent
thermal stability. Manufactured in
differing NLGI consistency classes
PETAMO greases cover a wide
range of applications and conditions.
Application
High-temperature lubrication of
rolling bearings, plain bearings,
electric motor bearings, load rollers
in conveyors, roller bearings in
continuous wood panel presses,
load rollers in continuous casting
machines.
Application notes
PETAMO greases can be applied by
spatula, brush, pressure grease gun
or via centralized lubrication
systems. (Petamo GHY 441 is the
preferred grade for automatic
dispensing). Prior to initial
application please check
compatibility with current greases
and pre clean bearings, where
necessary.
Minimum shelf life
The minimum shelf life is approx. 24
months if the product is stored in its
unopened original container in a dry
place.
