Klübersynth? GH 6 Oils
Synthetic gear and high-temperature oils
Description:
Klübersynth GH 6 oils are high-temperature
gear oils on a polyglycol
basis. They have an increased scuffing
load capacity and provide good
protection against wear. In the stringent
FZG test (A/16.6/140) these
oils had a scuffing load stage > 12
and a work-related loss in weight
0.2 mg/kWh. Klübersynth GH 6
oils are particularly resistant to
ageing and oxidation, they have a
good viscosity-temperature relationship
and show an excellent hightemperature
behaviour.
Fields of application:
Klübersynth GH 6 oils were
especially developed for the
lubrication of worm gears with
steel/bronze pairings. In this
application there are two interesting
aspects: the special polyglycol base
oils reduce the friction coefficient,
and the very efficient additives
minimize wear.
Klübersynth GH 6 oils are also suitable
to lubricate all types of bevel
and spur gears, plain and rolling
bearings as well as toothed couplings,
especially when exposed to
increased temperatures.
Application notes:
Klübersynth GH 6 oils can be
applied by immersion, immersion
circulation and injection. Observe
the manufacturer’s instructions
about the maximum viscosity that
can be pumped.
Klübersynth GH 6 oils are not miscible
with mineral oils and synthetic
hydrocarbons. We recommend
cleaning the lubrication points prior
to conversion, and rinsing gears or
closed lubricating systems with the
Klübersynth GH 6 oil that will be
used for lubrication.
Klübersynth GH 6 oils are neutral
towards ferrous materials and
almost all nonferrous metals. There
may be increased wear when the
contact surfaces of design elements
made of aluminium or aluminium
alloys are exposed to dynamic loads
(sliding speed and high loads). If
necessary, wear tests should be
carried out.
Depending on temperature and
exposure time, synthetic lubricants
on a polyglycol base may have an
impact on the functional capacity of
rubber-elastic sealing materials.
Seals made of NBR materials
(acrylonitrile-butadiene-rubber) can
be used at permanent temperatures
up to 100 °C. For higher temperatures
we recommend to use seals
made of FKM materials (fluorinated
rubber), i. e. elastomers which are
resistant to Klübersynth GH 6 oils.
It has to be taken into account
that different elastomer qualities
produced by one manufacturer or
different manufacturers may show a
different behaviour. For approximate
values about a change in volume
and hardness of NBR and FKM
materials in contact with Klübersynth
GH 6 oils refer to the table
“compatibility with elastomers”.
Paints may be attacked by synthetic
lubricants. When applying Klübersynth
GH 6 oils we recommend the
use of two-component paints (reactive
paints) for interior coating. Oil
gauge glasses should preferably be
made of natural glass or polyamide
materials. Other transparent
plastics, e. g. Plexiglas, have a
tendency to crack under stress.
We recommend testing the suitability
of design materials and paints in
contact with the selected lubricants,
especially for series application.
