The heat sink 3 is made of copper alloy, which has excellent thermal conductivity and high heat dissipation efficiency, and can quickly transfer heat from the bearing cage to the surrounding environment. A protruding plate 7 is provided on the outer side of the heat sink 3.

[0023] See Figure 2 , Figure 3 As shown, multiple convex plates 7 are provided, and the multiple convex plates 7 are evenly distributed.
