Abstract
A bearing assembly includes a split inner race ring configured to be installed on a shaft and defines two raceways for supporting rolling elements. A split clamping band is configured to be installed over the split inner race ring to secure the split inner race ring on the shaft. A split seal wear ring is configured to be installed on an outer diameter surface of the split clamping band. An engagement interface between the split clamping band and the split seal wear ring includes a boss on one of the split clamping band and the split seal wear ring, and an aperture on the other one of the split clamping band and the split seal wear ring. The aperture is sized and configured to receive the boss for positioning the split seal wear ring on the split clamping band.
