B.Bearing operation is not standard:

Answer: Improper installation, operation or disassembly of bearings may cause deformation or defect of the cage.

Precautions: use proper operating, installation and disassembly tools, and use genuine bearings with qualified specifications.

C.Bearing rust and corrosion:

Answer: contact with water may cause erosion and rust of bearing elements.Bearings damaged by rust may peel off during operation.

Preventive measures: check the seal regularly to ensure good sealing effect and properly store bearings.

D.Bearing current:

Answer: Power on the bearing during rotation may cause grooves or notches.When bearings are at rest, improper grounding of electrical operation can cause minor burns.

Precautions: Reduce or prevent current from passing through bearings by a proper grounding connection prior to welding parts other than bearings.
