SUMMARY
The torque of friction in a bearing refers to the torque required to turn a shaft within a bearing, overcoming the frictional forces present. In plain bearings, two surfaces slide against each other, necessitating a specific torque to counteract friction. Conversely, in ball or roller bearings, the rolling resistance of the balls generates a torque that must also be overcome. This concept is crucial for understanding mechanical systems, such as the performance of fidget spinners, which experience slowing due to both friction torque and air resistance.
