摘要： A lubricating composition includes an oil of lubricating viscosity and an ionic tetrahedral borate compound which includes a cation and a tetrahedral borate anion which includes a boron atom, the boron atom having at least one aromatic bidentate di-oxo ligand. The compound may be represented by formula (I), where R1 and R2 are selected from C1-48 hydrocarbyl groups or together form a substituted or unsubstituted 5- or 6-membered ring; R3 and R4 together represent a substituted or unsubstituted aromatic ring; m is 0 or 1; X is hydrogen, a C1-24 hydrocarbyl group, —OR5, —NHR5, or=O, R5 is a C1-24 hydrocarbyl group; M represents the cation; and n is at least 1. The cation may be selected to provide detergent and/or dispersant properties to the lubricating composition. In the case of ammonium cations, the molecular weight may be 260 g/mol or higher for providing a highly soluble compound, particularly when X is=O.

摘要： The present invention provides a grease composition or a lubricating oil composition which is capable of effectively preventing hydrogen brittleness-caused peeling from occurring on a rolling surface of a rolling bearing, is excellent in durability in a high temperature and speed operation, and can be used for a long time. A grease-packed bearing (1) has an inner ring (2), an outer ring (3), and a plurality of rolling elements (4). A sealing member (6) for sealing a grease composition (7) is provided at openings (8a) and (8b) disposed at both axial ends of the inner ring (2) and the outer ring (3). The grease composition (7) includes a base grease composed of a base oil and a thickener and an additive added to the base grease. The additive contains at least one compound selected from among plant-derived polyphenolic compounds and compounds formed by decomposition thereof. The above-described compounds include tannin, gallic acid, ellagic acid, chlorogenic acid, caffeic acid, curcumin, quercetin, and quinic acid.
