Ideally suited for high wear and increased load applications in industrial markets, QA1's GEZ Series fractured race spherical bearings are manufactured using 52100 bearing steel. Because of the strength of the steel, the race cannot be molded around the ball and therefore is fractured slightly to allow the ball to be inserted. The hardened and ground surfaces allow for full ball to race conformity, resulting in reduced wear, smooth operation and less localized stress.
