How often should the mainshaft bearings be greased in a rotating biological contactor unit?

In a rotating biological contactor (RBC) unit, regular maintenance of the mainshaft bearings is crucial for optimal operation and longevity of the equipment. Greasing the bearings every week is advisable because these components are subject to continuous movement and load, leading to wear and tear. Weekly greasing ensures that the bearings are properly lubricated, reducing friction and preventing overheating, which can cause premature failure. This frequency aligns with industry best practices for maintaining rotational equipment in demanding applications, ensuring that the bearings remain in good working condition and can support the operational demands placed on them effectively.
