Description

Technical Field

[0001] The utility model relates to the technical field of novel bearings, in particular to a high-sealing automobile ABS motor bearing. Background Art

[0002] ABS bearings used in automobiles are primarily composed of seven components: an outer ring, an inner ring, rolling elements, a retainer, a seal, a dust cover, and grease. Spherical rolling elements are installed between the outer and inner rings, evenly distributed between them and secured with a retainer. The seal prevents dust and oil from entering the bearing; the dust cover prevents dust and reduces the bearing's rotational torque; and the grease lubricates and forms an oil film, extending its lifespan.

[0003] For example, Chinese patent publication number CN219639265U discloses a high-speed magnetic ring bearing for a starting motor, which includes an inner ring, an inner peripheral wall of the inner ring is provided with a fixing groove, the fixing groove is provided with a fixing ring, the fixing ring is bent outward along the inner peripheral wall of the inner ring and extended to form a connecting ring, the connecting ring is provided with a magnetic part, and a fixing piece for partially fixing the connecting ring to the side wall of the inner ring is provided at the connection between the connecting ring and the inner ring, and the connecting ring rotates in coordination with the inner ring.
