PROBLEM TO BE SOLVED: To provide a rolling bearing capable of simplifying a structure of a seal with a grease pocket and grease filling work in a sealed bearing having superior insulation performance. SOLUTION: The cylindrical roller bearing 31 includes an inner ring 32, an outer ring 33 which has the same width with the inner ring 32 in an axial direction and forms insulation layers on an outer diameter surface and both end faces, cylindrical rollers 34 arranged between the inner ring 32 and outer ring 33, a retainer 35 for retaining the cylindrical rollers at regular intervals, and a seal 36 as a sealing member, which seals both ends of the bearing. The seal 36 has a projecting shape with a sectioned C-shape from both ends of the inner ring 32 and outer ring 33, and is formed by injection molding of a resin material. COPYRIGHT: (C)2007,JPO&INPIT
