PROBLEM TO BE SOLVED: To provide a rolling bearing with a filter which prevents the entry of foreign substances in a lubricant into the bearing, and can improve a peeling resistance life of a bearing raceway surface by decreasing the amount of the foreign substances in the lubricant.SOLUTION: A filter 110 is shaped in a hollow disc, and made from double filters of an inside filter and an outside filter. The outside and inside filters of te filter 110 are provided with a plurality of oil leading holes 110a alternately in a radial direction. The filter 110 is formed by a material having magnetism such as rubber magnet or plastic magnet. Therefore, when a lubricant flows into a bearing 101a from an exterior space, the lubricant passes through the oil leading holes 110a of the filter 110. At that time, the filter having magnetism positively adsorbs and/or collects friction powders almost made from iron in the lubricant.SELECTED DRAWING: Figure 1 |
