Castrol Molub-Alloy 777 NG Range
Product Description
MOLUB ALLOY™ 777 NG greases were designed for very heavy-duty service under severe ambient conditions. They are blended and compounded to withstand shock loads as well as heavy loads, conditions commonly found in the steel and construction industries, in mining and forestry.
MOLUB ALLOY 777 NG greases are made with a blend of high-viscosity mineral oils and polymers which produce a tough lubricating film capable of withstanding shock loads and vibrations.
The shear-stable thickener provides an excellent sealing effect against contamination from the atmosphere, even if mechanical seals are damaged or missing (grease collar in the bearing).
The lubricating greases contain solid lubricants whose structure is best suited for the rugged conditions in heavy industry. The solids are treated to increase their natural affinity to metal surfaces.
Corrosion and oxidation inhibitors maximize the corrosion protection and aging stability of the base oil.
777 NG greases are free of antimony, lead, zinc and other heavy metals.
Application
Typical applications are in all types of rolling and sliding bearings, spindles, joint couplings (except for highspeed precision couplings), running gears, cams and general grease lubricating points, especially where heavy loads and low speeds prevail.
MOLUB ALLOY 777 NG greases are especially suited for the lubrication of heavy machines e.g, forging presses or hauling machines. Due to the extremely stable lubricating film, supported by the solid lubricant combination in the mixed friction area as well as the excellent sealing effect, a quantity reduction and an improved lubricating condition ca be ensured.
Advantages
Due to their good adhesion these greases provide an optimum sealing effect.
The MOLUB-ALLOY solid lubricants achieve reduced friction in the boundary and mixed friction areas. This is most evident during frequent start-ups, low speeds and/or high loads as well as shock loads.
Overall savings are derived from the above which in turn result in less repair work and downtime, longer service life of components and extended lubrication intervals.
