Molub-Alloy 777ES
Castrol Molub-Alloy™ 777 ES greases are designed for very heavy
duty service in adverse environments.

    They are blended and compounded to withstand heavy and shock
    loading, commonly found in the steel/primary metals, construction,
    mining, and forest products industries.
    Molub-Alloy 777 ES greases are made using a blend of high quality
    petroleum oils, polymers and a proprietary blend of Molub-Alloy
    lubricating solids. These lubricating solids work synergistically with
    chemical anti-wear and extreme pressure (EP) additives to reduce
    contact temperatures and wear while providing the ultimate in
    extreme pressure and shock load anti-weld protection. This blend
Molub-Alloy 4086
Castrol Molub-AlloyTM 4086 high-performance bearing grease is a heavy-duty all-weather grease manufactured from
high-quality components, carefully selected for their compatibility with Molub-Alloy lubricating solids. Molub-Alloy
4086 has good film strength and is formulated to protect against friction and wear under heavy loading due to a
proprietary blend of Molub-Alloy solid lubricants.
Molub-Alloy 6780 Wide Temp Grease
Castrol Molub-Alloy® 6780 is a .wide temperature bearing grease designed for year-round service in both bushings
and antifriction bearings. Castrol Molub-Alloy® 6780 matches the tough service requirements of mining applications,
including bearings and bushings of excavating equipment subjected to broad service temperature ranges as well as
offroad mobile equipment general lubrication. Castrol Molub-Alloy® 6780 was developed with emphasis on the
following performance characteristics:
Tribol 1100 Series Gear Oil
Castrol Tribol® 1100 Gear Oils are manufactured from the highest quality pretroleum base oils. Blended into this oil
is the latest developement in the filed of surface improving additives designated TGOA. TGOA is an oil soluble
additive package designed to reduce friction while providing surface protection and improvement. The TGOA
additive package offers superior performance because of its unique action on frictional surfaces.

    TGOA works by establishing a highly protective metal rich lubricating film. This film is formed by the reaction of
    TGOA additives due to frictional heat and the catalytic action of metallic surfaces. The results are a smoothing of
    surface roughness without creating abrasion. Therefore, surface roughnesses are reduced without the usual loss of
    surface material.
Optimol Optigear BM Series
Castrol Optimol Optigear® BM is a solid-free, high performance gear oil. Wear problems such as abrasion, surface
fatigue (pitting), grey staining, or problems during the running-in phase are controlled. Castrol Optimol Optigear® BM
contains Microflux Trans® which is an additive system that adjusts itself to changing loads and actively prevents wear.
Molub-Alloy 936 SF Open Gear Grease
CASTROL MOLUB-ALLOY™ 936 SF is a uniquely compounded open gear lubricant developed specifically for use on
heavy-duty equipment in mining and industrial service. It forms a tough lubricating film on the friction surfaces which
is resistant to pressure and shock loads as well as unfavorable ambient conditions. The structural integrity and
strength of the lubricating film is particularly valuable in the critical process of running in new gears because of the
natural occurrence of high spots (asperities) in newly machined surfaces. The lubricating film must separate the
mating surfaces sufficiently to cushion the effect of the impact of asperities, and thus minimize initial pitting which
could lead to progressive and destructive pitting later.
EP Grease for Bearings & Bushings
Correct Grade for Temp
    together with a shear stable thickening system provides a uniquely effective seal against loss of grease or
    contamination from the atmosphere, even where mechanical seals may be damaged. Rust and oxidation inhibiting
    characteristics are maximised to afford effective rust protection and long life of the grease.
Swing Gearcases
Enclosed Gearcases (e.g. Hoist & Drag Drum)
Open Gears, Dragline Shovels,
and Swing Rack & Rollers
(Arctic, Light, Medium, Heavy)
    The results of the TGOA process can be compared with a rolling
    process in the micro-range. The surface roughnesses are
    gradually leveled and smoothed. Through this smoothing action,
    the actual load-bearing area is enlarged with the loads being
    distributed over increasing areas. Therefore the actual load per
    unit of working area decreases.
    If surface roughness peaks redeveloped because of shock loads
    or stop-and-go operation, the TGOA additive package is
    automatically reactivated. Surface roughnesses are again
    smoothed and lubrication optimized.
    Castrol Tribol® 1100’s have passed the harsh Cincinnati Milacron
    Thermal Stability Test. This test evaluates copped and steel
    corrosion and oxidation stability. Castrol Tribol® 1100 Gear
    Oils are approved as P 74, P 59, and P 35 for the ISO 220, 320,
    and 460 grades respectively.
    A highly refined, viscous, paraffinic petroleum derivative is the
    foundation of a blended base fluid with excellent natural chemical
    and thermal stability. CASTROL MOLUB-ALLOY™ 936 SF is
    compounded to flow readily in the film-forming process, yet it
    resists "squeeze-out" and clings tenaciously even to gear teeth in
    vertical orientation.
    A proprietary blend of CASTROL MOLUB-ALLOY™ lubricating
    solids is included in particle sized suitable for open gears to
    promote antiwear properties.
    Rust and oxidation inhibitors are included in the formulation to
    protect the equipment and the lubricating film against the elements
    in severe climates.
  • Broad service temperature application range for year-round service.

  • Work-shear stability to be effective in severe mining and off-road
    mobile equipment applications.

  • Resistance to the washing action of water.

  • Castrol Molub-Alloy® 6780 consists of premium petroleum and
    synthetic fluids blended to ISO 68 Viscosity Grade and thickened with a
    Calcium (12-OH) soap. For ease of pumping in cold climates, 6780 is
    formulated to NLGI Grade Number 1.

  • Castrol Molub-Alloy® 6780 contains a proprietary blend of solid
    lubricants together with extreme pressure - (EP) chemical additives
    which work synergistically to provide the high, degree of antiwear and
    EP characteristics required in heavy duty off-road service.

  • To provide corrosion protection in wet seasons and protection from
    aging in long service at high temperatures, 6780 is further fortified with
    effective rust and oxidation inhibitors.
