The invention discloses a novel high-strength wear-resistant bearing including an outer ring, fixing blocks, fixing parts, main steel balls, vice steel balls, an inner ring, sealing gaskets, a main limit ring, vice limit rings, a shaft hole, a first wear-resisting layer, and a second wear-resisting layer. The novel high-strength wear-resistant bearing is provided with the main steel balls and the vice steel balls, all-dimensional sealing type connection of three sides of the inner ring is achieved, the strength of the bearing is increased, and the bearing is not easily eccentric; at the same time, the bearing is formed by splicing assembly of multiple components, installation is more convenient and saves labor, and the production efficiency is increased; and the first wear-resisting layer and the second wear-resisting layer are arranged, so that the wear resistance of the main steel balls and the vice steel balls with the outer ring can be increased, and the service life of the bearing is increased.
