Product Description
RONEX EXTRA DUTY MOLY 2 is a premium high-base-oil-viscosity grease designed
for the heavy-duty applications often encountered in paper mills,
construction, commercial vehicles, and mining environments. Designed with
ExxonMobil's proven lithium complex thickener system, RONEX EXTRA DUTY MOLY 2
provides the reliable, engineered shear-stability needed for off-highway
applications operating under heavy-duty conditions. Formulated with
outstanding water resistance and tackiness properties, RONEX EXTRA DUTY MOLY 2
demonstrates excellent performance in wet and dirty environments.
Features and Benefits
Extreme-Pressure Performance The wear protection provided by the
high-viscosity base oil in RONEX EXTRA DUTY MOLY 2 is enhanced with special
extreme-pressure (EP) and anti-wear (AW) additives. These additives, which act
chemically to protect bearing surfaces at high loads, give RONEX XTRA DUTY
MOLY 2 wide load-carrying capability - sufficient to meet the most demanding
operating conditions. Whether the application requires low load protection,
high load protection, or protection from fluctuating load conditions, RONEX
EXTRA DUTY MOLY 2 is engineered to handle the job.
Extra Tackiness and Water Resistance RONEX EXTRA DUTY MOLY 2 exhibits
a high degree of tackiness and self-adhesion, which enhances the grease's
ability to hold tenaciously to lubricated surfaces, and cling to bearing
surfaces in severe water environments.
Rust and Corrosion Protection RONEX EXTRA DUTY MOLY 2, applied to
rust-and corrosion-free surfaces, is specifically formulated to protect
against rust and corrosion.
Excellent Shear Stability Grease shear stability is a critical
performance feature for the successful lubrication of bearings. RONEX EXTRA
DUTY MOLY 2 has outstanding shear stability, which translates to an ability to
maintain consistency under shear, and provide lubrication:
Pumpability RONEX EXTRA DUTY MOLY 2 is pumpable down to -10ºC (14ºF).
Below this temperature, grease with a lower base oil viscosity should be used.
Use of a lower-viscosity-base-oil grease, however, will necessitate more
frequent relubrication.
Good Compatibility with Other Greases RONEX EXTRA DUTY MOLY 2 is
compatible with most competitive lithium-based greases. Two greases are
considered compatible when the consistency (penetration value) of the product
mixture is within the limits of the calculated average consistency. Other
factors that are impossible to predict include, unexpected chemical
interactions in the bearing from outside contamination and physical
interactions from in-situ field products.
In summary, RONEX EXTRA DUTY MOLY 2 offers the following benefits:
- Wide load carrying capacity
- High degree of tackiness and adhesion
- Rust and corrosion protection
- Outstanding shear stability
- Good pumpability
Applications
RONEX EXTRA DUTY MOLY 2, a gray-black NLGI 2 grease containing 3% molybdenum
disulfide, is particularly recommended for applications such as bucket pins
and fifth wheels, where vibrating or oscillating movement can squeeze out the
grease. In these cases, the 3% molybdenum disulfide affords an important
measure of residual lubrication when the grease has been displaced.
RONEX EXTRA DUTY MOLY 2 is also effective in lubricating pins and swivels,
where the sliding work action often requires a solid lubricant. Because these
applications are often associated with wet environments, the excellent water
resistance of RONEX EXTRA DUTY is another plus.
A difference in base oil viscosity gives RONEX EXTRA DUTY MOLY 2 and RONEX MP
greases distinctly different performance capabilities. With its higher base
oil viscosity of ISO 460 (2500 SUS), RONEX EXTRA DUTY MOLY 2 is recommended
for high load applications at slow-to-moderate speeds, including applications
in the paper, construction, and mining industries, as well as off-highway
vehicles operating at 35 mph or less. RONEX MP, with its much lower base oil
viscosity of 767 SUS, is designed to meet a wider range of high-speed
industrial and automotive bearing applications, including wheel bearings in
on-highway use.

Health and Safety
Healthy skin condition depends on cleanliness. Oils and greases in contact
with skin can result in plugging of sweat glands and hair follicles. This may
lead to skin irritation or dermatitis. Accordingly, protective gloves,
clothing and equipment should be worn and good personal hygiene should always
be practiced. Oils, greases, and other foreign materials should be removed
from the skin promptly. Soiled clothing should not remain in contact with the
skin. RONEX EXTRA DUTY MOLY 2 is readily removed from the skin by waterless
hand cleaners followed by washing with soap, warm water, and a skin brush. It
can be removed from clothing by dry-cleaning with solvents or by washing with
laundry detergents. If RONEX EXTRA DUTY MOLY 2 comes in contact with the eyes,
flush the eyes with fresh water until the irritation subsides.
As in the case of all greases, if there is a puncture wound with grease
contamination, or an injury where grease is injected into body tissue, such as
a "grease gun injury," prompt medical assistance should be obtained.
WARNING: "Empty" containers retain residue (liquid and/or vapor) and can be
dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind, or
expose such containers to heat, flame, sparks or other sources of ignition;
they may explode and cause injury or death. Do not attempt to clean since
residue is difficult to remove, and even a trace of remaining material
constitutes an explosive hazard. "Empty" drums should be completely drained,
properly bunged, and promptly returned to a drum reconditioner. All other
containers should be disposed of in an environmentally safe manner and in
accordance with governmental regulations.
