Can I use a vacuum cleaner to clean ball bearings?

It is not recommended to use a vacuum cleaner to clean ball bearings. Although a vacuum cleaner can effectively remove some surface dust, it cannot precisely control the suction and direction, which may cause pollutants to further enter the bearing interior and even damage precision components. In addition, excessive suction of the vacuum cleaner can cause certain impact on the bearings, which may result in damage to the ball bearings or raceways of the bearings. The correct cleaning method should be to use specialized cleaning tools such as compressed air, soft brushes, or cleaning agents to remove surface dust and ensure that there are no debris inside the bearings. If a more thorough cleaning is required, it is best to disassemble the bearings and use suitable cleaning solutions and tools for cleaning.
