Feeling a roughness while rotating a shaft is an important indication of potential bearing failure. In a well-functioning bearing system, the shaft should rotate smoothly with little to no friction. When roughness is detected, it suggests that there may be wear or damage occurring within the bearing surfaces. This could be due to several factors such as lack of lubrication, contamination, or physical damage to the bearings.

Identifying this roughness early allows for timely maintenance actions to prevent further damage or complete failure of the bearing system, which could lead to more significant mechanical issues. Regular monitoring and maintenance practices are essential to ensure the longevity and reliability of rotating machinery.
