A wear-resistant automotive rocker arm bearing

Abstract

This utility model discloses a wear-resistant automotive rocker arm bearing, belonging to the field of bearing technology. It includes an outer bearing ring, an inner bearing ring disposed within the outer bearing ring, a cage disposed between the outer and inner bearing rings, and balls rotatably mounted on the cage. It also includes two side retainer rings, each located on opposite sides of the inner bearing ring. A cavity for mounting the cage is formed between the outer and inner bearing rings. The side retainer rings close the openings at both ends of the cavity. Each side retainer ring includes a support ring and a sealing ring mounted on the outer peripheral wall of the support ring. The support ring is fixedly connected to the inner bearing ring, and the sealing ring provides a sealing abutment against the outer bearing ring. This wear-resistant automotive rocker arm bearing prevents impurities from entering the cavity through the side retainer rings and also prevents internal sealing grease from falling off, significantly reducing ball wear and extending service life.
