When the bearing makes noise during operation, the noise-proof groove absorbs and consumes the noise, thereby ensuring the silent operation of the bearing. Meanwhile, when the bearing generates high temperature during operation, the bearing roller transfers heat into the interior of the detection groove through the heat-conducting member. At this time, organic matter in the white oil inside the detection groove decomposes, and an oily odor is generated by the decomposition of the organic matter. The oily odor is discharged through the detection discharge hole. When the worker inspects the elevator winch, the worker can directly judge whether the bearing is running at a high temperature by the oily odor emitted by the bearing, thereby facilitating the worker's inspection and maintenance of the bearing, facilitating the worker's operation, avoiding the worker's temperature measurement of the bearing, and improving the inspection and maintenance efficiency of the bearing.

At this time, the organic matter in the white oil inside the detection groove 502 decomposes at high temperature, and the decomposed organic matter produces an oily odor. At this time, the oily odor is discharged through the detection discharge hole 504. At this time, the maintenance personnel can judge the operating temperature of the bearing by the oily odor, which facilitates the maintenance of the bearing.
