Abstract:
The present invention relates to a non-hydroxide grease composition comprising a base oil and a thickener which comprises amorphous hydrophilic silicon oxide particles and one or more metal salts of different organic acids, wherein the silicon oxide particles have a BET specific surface area of at least 50 m2/g and wherein the amount of the metal salt(s) is 4- 25% by weight, based on the total weight of the grease composition. The present invention further relates to a method for manufacturing said grease composition and the use of said grease composition for lubricating a bearing and in couplings and gearings.

Abstract:
The present invention relates to a grease composition comprising a base oil, amorphous silicon oxide particles and at least a first metal salt of an organic acid and a second metal salt of an organic acid, in which the at least first metal salt and the second metal salt differ from each other, and wherein the total amount of the silicon oxide particles and the metal salts of the organic acids is 0.1-40% by weight, based on the total weight of the grease composition. The present invention further relates to a method for manufacturing said grease composition and the use of said grease composition for lubricating a bearing and in couplings and gearings.
Abstract:
The present invention relates a method for manufacturing a grease composition comprising as components a base oil, amorphous silicon oxide particles and at least one metal salt of an organic acid, which method comprises mixing the components in any possible order of sequence and subjecting before or after mixing at least one of the components to a mechanical treatment, a thermal treatment or to both a mechanical treatment and a thermal treatment.
Abstract:
The present invention relates to a grease composition comprising a base oil, amorphous silicon oxide particles and a metal salt of an organic acid comprising 18 carbon atoms, wherein the total amount of the silicon oxide particles and the metal salt of the organic acid comprising 18 carbon atoms is about 0.1-40% by weight, based on the total weight of the grease composition. The present invention further relates to a method for manufacturing said grease composition and the use of said grease composition for lubricating a bearing and in couplings and gearing systems.
