[0028] In addition, it should be noted that the design of the water-lubricated bearing body 1 uses water as a lubricating medium to form a stable lubricating film, reduce direct friction between the contact surface of the shaft and the bearing, and achieve a low friction coefficient. Through the cooperation of the spiral guide component 5 and the radial guide component 4, the water flow in the bearing forms an efficient flow path, which not only provides sufficient lubrication, but also reduces the friction coefficient by reducing turbulence and fluid resistance.
