This utility model discloses a bass bearing with noise reduction function, including a hollow corrugated shell, an outer ring fixedly installed inside the hollow corrugated shell, and an inner ring rotatably installed inside the outer ring. Both ends of the inner ring surface are fixed with cages, and several equally spaced balls are embedded inside the cages, contacting the inner wall surface of the outer ring. A rubber bushing is fixed to the inner wall of the inner ring, and a fan-shaped protrusion is integrally formed on the outer wall of the rubber bushing. The end of the fan-shaped protrusion extends outward and penetrates to the outside of the inner ring. This utility model, through the interlocking structure of the inner ring, rubber bushing, fan-shaped protrusion, and cage, allows the inner ring to roll and rub against the outer ring via the cage and balls. During this rolling friction, the rubber bushing in the inner ring continuously contacts the double-wing elastic oil overflow structure via the fan-shaped protrusion, causing grease from the polyurethane foam block to overflow.
