PROBLEM TO BE SOLVED: To provide a rolling bearing in which abrasion or deformation is unlikely to occur even when used under a high load. SOLUTION: An inner ring 1 and an outer ring 2 of a deep groove ball bearing are composed of polyolefin resin composition, and a rolling element 3 is composed of glass. The polyolefin resin composition comprises polyolefin as a resin component and potassium titanate whisker as reinforcement material. The polyolefin comprises ultra-high molecular weight polyolefin and low molecular weight to high molecular weight polyolefin. Under the presence of ultra-high molecular weight polyolefin, the low molecular weight to high molecular weight polyolefin is generated. COPYRIGHT: (C)2005,JPO&NCIPI
