Why Coupling Grease?
Ample lubrication is crucial for satisfactory gear coupling operation. Gear Coupling Grease is specifically designed for gear coupling applications to boost coupling life whilst significantly decreasing maintenance time. Its higher viscosity base oil and tackifier mix to maintain the grease in location and avoid separation and it can be in total compliance with NSI/AGMA 9001-B97 lubrication suggestions.
Coupling Grease is dark brown in color and produced with a lithium soap/polymer thickener, which has superior resistance to oil separation when subjected to large centrifugal forces normally discovered in couplings. Bearing or general goal greases have a tendency to separate and get rid of effectiveness because of large centrifugal forces about the a variety of substances at high rotational speeds. These higher centrifugal forces encountered in couplings separate the base oil from your thickeners. Hefty thickeners, which have no lubrication attributes, accumulate within the gear tooth mesh area leading to premature coupling failure. Gear Coupling Grease is intended to extremely resistant to centrifugal separation in the oil and thickener, which lets the lubricant to get applied to get a fairly lengthy period of time.
One of many secrets towards the achievement of Gear Coupling Grease would be the variable consistency throughout the working cycle in the application. The consistency of our gear coupling grease modifications using the operating problems. Working with the lubricant underneath actual service problems leads to the grease to turn out to be semi-fluid, functionally solash lubricating the put on surfaces with the coupling. Because the grease cools, it returns towards the original consistency, thereby stopping leakage.
Gear Coupling Grease is obtainable from stock in 14 oz. cartridges, 1 lb. and five lb. cans.
