[0024] Specifically, the ball 5 is located between the outer ring 1 and the inner ring 2, a lubricating ring 7 is arranged on the surface of the ball 5, the lubricating rings 7 and the communicating pipes 8 are sequentially connected into a ring shape, the lubricating rings 7 and the communicating pipes 8 are interconnected, the oil inlet pipe 11 and the communicating pipe 8 are interconnected, the inside of the sealing cover 10 is matched with the thread 9 arranged at one end of the oil inlet pipe 11, and by rotating the sealing cover 10, the sealing cover 10 can be installed and disassembled at one end of the oil inlet pipe 11 under the cooperation of the thread 9. After the sealing cover 10 is disassembled from the thread 9, lubricating oil can be injected into the communicating pipe 8 through the oil inlet pipe 11. The lubricating oil can be injected from different positions through the uniform distribution of the four oil inlet pipes 11. The lubricating oil enters the lubricating ring 7 from the communicating pipe 8. When the ball 5 rolls, it contacts the lubricating ring 7, and the lubricating oil flows out from the small holes where the lubricating ring 7 contacts the ball 5 to enhance the lubrication effect.
