The outer bearing ring is located outside the outer periphery of the inner bearing ring. A ball cage is provided between the outer bearing ring and the inner bearing ring. The ball cage has a ball groove inside, which is a closed structure. A plurality of balls are movably installed in the ball groove. A mudguard ring mounting groove is jointly enclosed on both sides of the outer bearing ring and the inner bearing ring. A first mudguard ring and a second mudguard ring are respectively installed in the two mudguard ring mounting grooves. Both the first mudguard ring and the second mudguard ring are fixedly connected to the inner bearing ring. A first sealing ring adapted to seal the first mudguard ring and the second mudguard ring is fixedly installed on the outer bearing ring at the mudguard ring mounting groove.

[0005] Preferably, the ball cage includes a first half and a second half, the first half being fixedly connected to the outer wall of the bearing inner ring, and the second half being fixedly connected to the inner wall of the bearing outer ring.

[0006] Preferably, a second sealing ring is fixedly installed on the inner wall of the outer ring of the bearing, which is adapted to dynamically seal the outer wall of the first half of the bearing.

[0007] Preferably, a third sealing ring is fixedly installed on the outer wall of the bearing inner ring, which is adapted to dynamically seal the inner wall of the second half of the bearing.

[0008] Preferably, the outer surfaces of the first mudguard ring and the second mudguard ring are arched structures.

[0009] Preferably, the ball bearing retainer, the first mudguard ring, and the second mudguard ring are all made of heat-dissipating metal material.

[0010] In summary, the technical effects and advantages of this utility model are as follows:

[0011] In this invention, an external first mud-blocking ring and a second mud-blocking ring serve as the first mud-blocking barrier, while a closed ball bearing retainer serves as the second mud-blocking barrier, achieving a highly efficient mud-blocking effect. Attached Figure Description

[0020] Example: Reference Figure 1-2 An improved mudguard bearing, as shown, includes an outer ring 1, an inner ring 2, a ball cage 3, balls 5, a first mudguard ring 7, a second mudguard ring 8, and a first sealing ring 9. The outer ring 1 is located outside the outer periphery of the inner ring 2. A ball cage 3 is provided between the outer ring 1 and the inner ring 2. The ball cage 3 has a ball groove 4 inside, which is a closed structure. Several balls 5 are movably installed in the ball groove 4. The outer ring 1 and the inner ring 2 together enclose the bearing on opposite sides. There is a mudguard ring mounting groove 6, and a first mudguard ring 7 and a second mudguard ring 8 are respectively installed in the two mudguard ring mounting grooves 6. The first mudguard ring 7 and the second mudguard ring 8 are both fixedly connected to the inner ring 2 of the bearing. The outer ring 1 of the bearing is located in the mudguard ring mounting groove 6 and a first sealing ring 9 that is adapted to seal the first mudguard ring 7 and the second mudguard ring 8 for mudguard sealing. The external first mudguard ring and the second mudguard ring serve as the first mudguard barrier, and the closed ball retainer serves as the second mudguard barrier, achieving a highly efficient mudguarding effect.

[0021] With the above structure, the ball retainer 3 includes a first half 10 and a second half 11. The first half 10 is fixedly connected to the outer wall of the inner ring 2 of the bearing, and the second half 11 is fixedly connected to the inner wall of the outer ring 1 of the bearing, thus forming an annular retainer.
