Aluminium complex greases
Third Quarter 2021
Other technologies
While no grease can truly be an all-purpose lubricant, aluminium complex grease is a valuable multifunctional, multipurpose product. Applications include vehicle wheel bearings, manufacturing and assembly plants, steel mills, boat trailers, paper mills and the rubber, textile and agricultural and construction industries. Aluminium complex greases are easy to pump at low temperatures because of their relatively low soap content and higher oil content. They readily accept extreme pressure additives, plus all the usual rust and oxidation inhibitors and speciality additives. Formulations of specially selected oils and additives can also be made to produce sophisticated lubricants for different temperature conditions.
Lubrication Engineers’ aluminium complex greases include the company’s proprietary and exclusive wear-reducing additives. The products also offer good heat reversion characteristics. This is the ability of the grease to revert to its normal consistency after it has been heated and cooled repeatedly.
Many industrial and automotive applications involve intermittent temperatures within a bearing that will approach or exceed the dropping point of the grease. If the grease in such an application does not maintain very nearly its initial consistency, the bearing is a candidate for failure. Aluminium complex greases also excel in resistance to both washing out of a bearing and being washed off a flat surface. This resistance to water washout is very important where it is necessary to prevent lubricating grease from entering plant discharge water. It also cuts down on lubricant consumption. The shear stability of aluminium complex grease is only moderately affected by water in the grease.
