The ball 8 is placed in the pocket hole 7 opened in the installation column 6, and can rotate flexibly in the inner wall of the pocket hole 7. When the bearing starts with the equipment, the ball 8 rotates in a groove of the rotating disc 16, and at the same time, the ball 8 rolls in the pocket hole 7, which greatly reduces the friction when rotating, and realizes low friction rotation. In the process of high speed operation of the bearing, the shape memory alloy 10 can quickly perceive and absorb the heat generated by the ball 8. After feeling the temperature change, it changes shape and starts to extend until it contacts the heat pipe 14.
