Maintenance of spherical bearings with seats
Clean
When removing the bearings for inspection, first use methods such as taking photos to record the appearance. In addition, it is necessary to acknowledge the amount of remaining lubricant and sample the lubricant before cleaning the bearings.
In order to distinguish whether the removed bearings can be used from scratch, emphasis should be placed on checking their standard accuracy, rotational accuracy, internal clearance, as well as their mating surfaces, raceway surfaces, mounting brackets, and sealing rings. Regarding the inspection effect, it can be distinguished by those who are used to bearings or know the bearings. The judgment criteria vary depending on the mechanical function, importance, and inspection cycle. If there is any damage, the bearings must not be used from scratch and it is necessary to exchange them.
