Product Data
Castrol Molub-Alloy
Gear oils
Description
Castrol Molub-AlloyTM gear oils were developed for the lubrication of enclosed gears. They are manufactured from
the highest quality components that have been carefully selected for their compatibility with Molub-Alloy lubricating
solids.
Load carrying capabilities are derived from Molub-Alloy's formulation and the proprietary blend of lubricating solids.
These metallic lubricating solids are treated to increase their natural affinity for metal surfaces. Also, they are
completely dispersed to assure effectiveness over the life of the oil.
Rust and oxidation inhibiting characteristics are maximized to afford effective rust protection and long service life.
Application
Molub-Alloy gear oils are recommended for spur, helical, herringbone, and straight or spiral bevel gears. They are
especially suited for heavy duty and shock loading where Extreme Pressure (EP) characteristics are required. They
should not be used where gear manufacturers specify the use of non-EP lubricants. For severe worm gear service
where ‘compounded’ gear oils are recommended use Molub-Alloy 170 W / 680.
Molub-Alloy gear oil 300 S / 1000 is especially suited for service in enclosed gears for heavy-duty industry and
mining machinery.
Advantages
• Reduced friction, most evident under boundary conditions, is directly attributed to the presence of specially
compounded lubricating solids. This benefit is most pronounced where frequent start-up, slow speeds, and high
and unexpected loads are encountered.
• The establishment of a protective layer of Molub-Alloy solids provides substantial increase in the working life of
both parts and lubricant. This increases load bearing area which can reduce unit pressures operating
temperatures, and wear.
• Realistic energy savings are possible through a reduction in peak power demand during cold start-up.
• Seal leakage is greatly reduced. Only compatible base oils that control rubber swelling tende
