Crossed Roller Bearing is a bearing with compact structure in which the rollers are arranged so that they cross between the inner ring and the outer ring. Since the rolling surface is line contact, elastic displacement based on bearing load is extremely minimal, and in addition, it is able to receive complicated loads consisting of radial load, axial load, and moment at the same time. This bearing is broadly used in revolving parts that require compactness, high rigidity, and revolution accuracy such as industrial robots, machine tools, and medical equipment. Furthermore, we also manufacture bearings made of stainless steel, and those with attachment holes in inner and outer rings, so please make inquiries at FRB Bearings.
