FULL COMPLEMENT ROLLER BEARING PACKED WITH GEL-LIKE LUBRICANT

摘要

A rolling-contact bearing has an outer ring, an inner ring or a shaft rotational relative to the outer ring and a full complement of rollers disposed for rotation between the outer ring and the shaft. A semisolid gel-like lubricant composed of a mixture of a gelling agent and lubricating oil is packed into interstices or gaps between the outer ring and the rollers and among the adjacent rollers to retain surely the rollers on a circular inside surface of the outer ring. The gel-like lubricant is composed of the lubricating oil of mineral oil or base oil, and a powdery oil gelling agent based on amino acids.
