PROBLEM TO BE SOLVED: To provide a rolling bearing for steel equipment in which poor lubrication and the occurrence of rust are prevented by improving wear resistance and rust preventing property at a relative inexpensive initial cost by filling the rolling bearing with specific grease.SOLUTION: The rolling bearing for steel equipment according to the present invention has an outer ring, an inner ring and rollers, and is filled with grease composition containing calcium sulfonate complex as thickening agent. The rolling bearing for steel equipment in the present invention is preferred, in particular, for a rolling bearing used in a roll supporting device, such a bearing however is loaded with high load, so that a self-aligning roller bearing, a multi-row tapered roller bearings, multi-row cylindrical roller bearings and double-row ball bearings and the like can be used. |
