GREASE FOR HIGH-SPEED BEARING

PROBLEM TO BE SOLVED: To provide grease for a high-speed bearing sufficiently complying with high-speed revolution with a dmN value of ≥1,700,000 and allowing compactification and reduction in operation cost of a machine tool. SOLUTION: The grease for a high-speed bearing is obtained by blending a n...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide grease for a high-speed bearing sufficiently complying with high-speed revolution with a dmN value of ≥1,700,000 and allowing compactification and reduction in operation cost of a machine tool. SOLUTION: The grease for a high-speed bearing is obtained by blending a non-urea grease, which uses a composite amide lithium soap having an amide bond in a molecule as a thickener, with a urea grease using an urea compound as a thickener. The urea compound is obtained by reacting a polyisocyanate component with a monoamine component, and the monoamine component contains 46 mol% or more of aliphatic monoamines for the whole of monoamines.
