Abstract:
PROBLEM TO BE SOLVED: To provide a grease composition having abrasion resistance and heat resistance superior to those of a conventional lubricating agent or grease composition while having torque transmission properties equal to or higher than that of a conventional lubricant or grease composition, having excellent lubricity and long delamination life, and capable of preventing electrolytic corrosion of a bearing.SOLUTION: A grease composition includes a thickener and a base oil. In the grease composition, the base oil contains: (a) a hydrocarbon oil extracted from botoryococcus braunii and/or (b) a hydrocarbon oil obtained by hydrogenating the hydrocarbon oil.
Abstract:
PROBLEM TO BE SOLVED: To provide a thrust sliding bearing constituted of a synthetic resin capable of maintaining low friction properties for a long time, capable of preventing a stick-slip phenomenon in sliding, and capable of preventing abnormal friction sound caused by the stick-slip phenomenon. SOLUTION: A thrust sliding bearing 1 constituted of a synthetic resin includes a silicone grease interposed at the sliding interface between the upper side of a lower annular plate part 202 which defines the bottom of a lower annular recess 204 and the lower side of a thrust bearing piece 300 which is in sliding contact with the upper side and the lower side of an upper annular plate part 102, and at the sliding interface between the lower side of the upper part and the upper side of the thrust bearing piece. The silicone grease comprises: a base oil which is a silicone oil and has a dynamic viscosity at 25 DEG C of 100-500,000 cSt; and a thickener which has been added thereto so that the mixture has a consistency of 200-400.

Abstract:
The invention relates to a grease composition comprising a base oil and a thickener which comprises hydrophilic metal oxide particles and one or more amides which contain one or more unsaturated C-C bonds and/or at least one OH group, wherein the hydrophilic metal oxide particles have a BET specific surface area of at least 10 m 2 /g and at least 80% of the hydrophilic metal oxide particles have a particle size in the range of from 5 nm to 900 μm, and wherein the amount of the thickener is in the range of from 0.1-40% by weight, based on the total weight of the grease composition. The invention further relates to methods for manufacturing the grease composition, and the use of the grease composition for lubricating bearings, gears and couplings.
