ROLLING BEARING AND GREASE COMPOSITION TO BE USED THEREIN

摘要

A rolling bearing in which multiple rolling elements are disposed between an inner ring and an outer ring in such a state that the rolling elements can roll and which is filled with a grease composition that is obtained by adding three kinds of rust preventives to a base oil consisting of at least one mineral or synthetic oil and exhibiting a kinematic viscosity of 200 to 400mm 2 /s at 40°C and that exhibits a cone penetration of 300 to 400 and a yield stress at 40°C of 150Pa or less, said three kinds of rust preventives being a carboxylic acid-based rust preventive, a carboxylic salt-based rust preventive and an amine-based rust preventive.
