Castrol Molub-Alloy 777-2 ES - High Performance Grease - 4367

 

Castrol Molub-Alloy™ 777-2 ES grease is designed for very heavy duty service in adverse environments. It is blended and compounded to withstand heavy and shock loading, commonly found in the mining, construction and offshore industries. Molub-Alloy 777-2 ES grease is 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 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. Molub-Alloy 777-2 ES is a Bucyrus certified grease (with lubricating solids <5% by weight and <10μm max particle size).

Available in 18Kg tins

Castrol Molub-Alloy 1000 - Extreme temperature grease - 4372

Castrol Molub-Alloy 1000 - Extreme temperature grease - 4372

 

Castrol Molub-Alloy™ 1000 extreme temperature grease utilises synthetic base oils in conjunction with a blend of Molub-Alloy lubricating solids selected for high temperature service. The synthetic fluids in Molub-Alloy 1000 were selected for their controlled low volatility, minimum residue after evaporation and high VI for additional film strength at elevated temperatures. The combination of synthetic fluids and a unique thickening system offers physical stability in prolonged service at high temperatures. Molub-Alloy 1000 remains more pliable than conventional high temperature greases. As a result of the higher viscosity synthetic base fluids used in Molub-Alloy 1000, the film strength at elevated temperature is superior to that of petroleum base oils. It is also formulated with a combination of rust and oxidation inhibitors for prolonged service life without relubrication.

Available in 15.9Kg tins

 

Application

Molub-Alloy 1000 is designed for use in applications where elevated temperatures are encountered, heavy and shock loading occurs, and where bearing speeds are low to moderate. Molub-Alloy 1000 has been successfully used in a wide range of elevated temperatures industrial applications such as:

  • In overhead sealed trolley wheel conveyor bearings passing through paint drying ovens in an air conditioner manufacturing plant. Temperatures reached 180°C/356°F and relubrication cycles were every 8 months.
  • In overhead sealed trolley wheel conveyor bearings passing through a paint drying oven in an automotive assembly plant. Temperatures reached 185°C/365°F with relubrication cycles every 6 months.
  • In floor conveyor bearings passing through paint drying ovens in an automotive assembly plant. Temperatures of 190°C/374°F were reached with relubrication cycles every 6 months.
  • In overhead sealed trolley wheel conveyor bearings passing through paint drying ovens of a motorcycle assembly plant. After 4 months without relubrication in temperatures of 180°C/356°F, the bead of product on the outside of the trolley wheels was still soft and pliable. Relubrication cycles were every 6 months.
  • In a cement rotary kiln as a gas-seal lubricant to minimise hot gas leakage.

 

 

User benefits include:

  • Excellent friction reduction characteristics due to Molub-Alloy solid lubricants – easier start-up, reduced heat, and reduced energy leading to longer bearing life.

Castrol Molub-Alloy 2115-2 - High temperature grease - 4373

 

Castrol Molub-Alloy™ 2115 grease is a thermally stable high temperature synthetic bearing lubricant. It is formulated from an advanced synthetic fluid and thickened with a temperature stable non-soap base. Molub-Alloy 2115 includes a blend of performance additives and Molub-Alloy lubricating solids for exceptional wear protection and is designed to greatly extend service life and relubrication intervals in high temperature bearings.

Available in 6.8kg tins

 

Application

Primarily developed for extended service in oven conveyor bearings, Molub-Alloy 2115 is recommended for bearings operating in paint drying ovens, textile tentering frames, and similar applications where minimum reapplication and dripfree performance is required. Molub-Alloy 2115 can be used in continuous service at 250°C/482°F and may be exposed to intermittent temperatures up to 280ºC/536ºF. Forced draft ventilation should be used at temperatures exceeding 200ºC. Molub-Alloy 2115 can be applied manually or with automatic dispensing equipment.

 

 

User benefits include:

  • Thermally and chemically stable – unparallel resistance to oxidation at high temperatures therefore extending relubrication intervals without undue risk of under lubrication, lubrication starvation, or an increase in power draw.
  • Virtually inert below 300ºC/575ºF – resists the thickening and hardening that is typical of petroleum greases in high temperature service.
  • Even at high temperatures, Molub-Alloy 2115 is resistant to organic solvents and most chemicals, including strong acids, alkalis, and oxidising agents.
  • Low volatility – does not volatilise readily at high temperatures and/or when exposed to high vacuum.
  • Formulated to address environmental concerns – it is free of lead, chlorinated solvents, and barium.

 

Additional Information:

Molub-Alloy 2115 should not be mixed with other greases or oils. In case of doubt please consult your local Technical Services. Molub-Alloy 2115 has a very low order of toxicity at room temperature with no significant irritation to skin or eyes. At 200ºC/392ºF, small quantities of toxic fumes are generated. The use of 2115 above 200ºC is not recommended without the use of forced draft ventilation. At 300ºC/572ºF, 2115 decomposition begins to accelerate, and small amounts of highly toxic, potentially acidic vapours are formed. Positive draft ventilation to the atmosphere is essential. Clean-up may be difficult because of the excellent resistance to ordinary cleaners and solvents. However, there are some industrial cleaners (fluorinated solvents) which can be used effectively.

MOLUB-ALLOY 936 SF - 190KG DRUM

 

DESCRIPTION
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 unfavourable 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.
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.

 

Application

  • All types of open gears, rails and rollers, racks and pinions, dipper sticks and other slides and shovels and draglines.
  • CASTROL MOLUB-ALLOY™ 936 SF may be applied via automatic lubricating systems. With the adequate equipment CASTROL MOLUB-ALLOY™ 936 SF can be pumped at temperatures down to 0°C. In case no automatic systems are available CASTROL MOLUB-ALLOY™ 936 SF can also be applied manually.

 

Advantages

  • CASTROL MOLUB-ALLOY™ 936 SF forms a tough, durable lubricating film with a "cushioning" effect, even under extreme pressure and at very low speeds.
  • Resistant lubricating film to resist weather in severe climates
  • Easy and economic application of an adhesive lubricating film via automatic dispensing equipment over a wide temperature range
  • CASTROL MOLUB-ALLOY™ 936 SF was formulated as solvent-free lubricant and is also free of lead, antimony and barium

Castrol Tribol 4020-220-2 &amp; 4020-460-2 - Lithium Complex Grease - 4401

Castrol Tribol 4020-220-2 & 4020-460-2 -  NLGI 2 Multipurpose Lithium Complex Grease - 4401

 

Castrol TribolTM 4020 greases are formulated from highly-refined petroleum base oils, a lithium complex thickener, and Tribol Grease Oil Additive (TGOA), the latest advancement in the field of friction reducing and surface improving additive technology. These multi-service greases are designed to extend the service life of bearings in heavy-duty and elevated temperature applications.

The load-carrying, anti-wear, and friction reducing capabilities of Tribol 4020 greases exceed conventional complex greases due to the advanced TGOA additive technology. Under relatively high specific loads and related temperatures, this technology promotes a non-destructive smoothing of surface roughness in the micro-range. This smoothing effect reduces friction and leads to an increase of the actual load-bearing surface.

If surface roughness peaks redevelop because of shock loads or stop-and-go operation, the TGOA additive package automatically reactivates. Surface roughness is again smoothed and lubrication optimised.

 

Application

Tribol 4020 greases were formulated as multi-service lubricants for heavy-duty applications of plain and anti-friction bearings under medium-to-high loads. The TGOA additives are very effective in protecting the machined surfaces of bearings during the critical ‘running-in’ period. Good bearing surfaces are essential for long bearing life. Tribol 4020 is commonly used as a plant-wide lubricant in the automotive industry as well as industries where the preference is for a high-performance non-dark grease.

 

Advantages

  • Advanced TGOA additive technology – multiple benefits including reduced friction, temperatures and noise, increased load carrying ability, and superior surface protection.
  • Excellent water resistance – the coating film stays on the surface even in the presence of water.
  • Excellent mechanical stability and adhesion – the grease keeps its consistency in service ensuring long term protection and reduced consumption as film stays between lubricated surfaces.
  • Superior oxidation resistance – prevents corrosive activity on bearings in aggressive environments.
  • Formulated to address environmental concerns – it is free of antimony, barium, lead and zinc.
