QA1 GEZ Series Fractured Race Spherical Bearings
QA1 GEZ Series fractured race spherical bearings are for your high-wear and increased load applications. They are manufactured from strong 52100 bearing steel and given a protective coating for corrosion resistance. 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. That results in the QA1 GEZ Series bearings offering reduced wear, smoother operation, and less localized stress. Specific bearings (2RS) feature races with two rubber seals.
