PROBLEM TO BE SOLVED: To provide a new rolling bearing for a steel rolling mill capable of having excellent water resistance and maintaining a favorable bearing function for a long time. SOLUTION: In this rolling bearing 100 for a steel rolling mill, a plurality of rolling bodies 30 are rollingly arranged between an inner ring 10 and an outer ring 20, and lubricating grease G is filled. The grease G is produced by blending three kinds of rust-preventive agents, a carboxylic acid base rust-preventive additive, a carboxylate base rust-preventive additive, and an amine base rust-preventive additive with base oil produced of at least one of mineral oil and synthetic oil. Thereby, even if water is mixed, exfoliation caused by hydrogen generated from water and corrosion caused by water can be suppressed effectively. COPYRIGHT: (C)2010,JPO&INPIT |
