The higher the bearing speed, the impact on the bearing is mainly reflected in the following aspects:

1. Friction and heat: As the speed increases, the rolling friction and sliding friction inside the bearing will increase, resulting in an increase in friction speed, which in turn generates more heat. This increase in heat may not only increase the bearing temperature and affect the lubrication effect, but also accelerate the wear and fatigue of the bearing material.

2. Lubrication problem: High speed may cause the base oil of the grease to evaporate and dry, and the oil film to become smaller, which in turn affects the lubrication effect of the bearing. Poor lubrication will increase the wear and vibration of the bearing and may even cause the bearing to fail. In addition, high speed may also cause the grease to be thrown out of the bearing, further deteriorating the lubrication conditions.

3. Centrifugal force effect: At high speed, the centrifugal force of the bearing rolling element increases, which may cause the relative position between the components inside the bearing to change, affecting the normal operation of the bearing. At the same time, centrifugal force may also cause deformation of the bearing, reducing its stiffness and load-bearing capacity.

4. Noise and vibration: High-speed bearings are prone to generate greater noise and vibration, which will not only affect the overall performance of the equipment, but may also affect the working environment and the health of the user.

Therefore, when selecting and using bearings, it is necessary to fully consider the impact of speed on the bearings to ensure that the bearings can work normally within the appropriate speed range. At the same time, for high-speed bearings, more stringent lubrication, cooling and maintenance measures are required to extend their service life and ensure stable operation of the equipment.
