XEZ 71900 series is a typical series in machine tool spindle bearings, which can bear radial load and axial load at the same time. A thin race ensures the bearing can reach higher speed. High-quality ceramic balls are available with Chrome steel races so that bearings can be super accurate and long-lasting. Machine tool spindle bearings can be offered in standard sizes or customized sizes.
