Hi Virgil. Thank you for your question.

If the vibrating screen motor’s bearing is damaged, you can consider these problems as follow.

Firstly, if your vibrating screen is old machine, may the rigidity and base will influence bearing. Or working process damage the component.

Secondly, maybe the design of structure is main problem.

Thirdly, processing precision is not enough.

Fourthly, there is a large error for barycenter of vibrating screen.

The fifth reason is unqualified bearing.

The sixth reason is incorrect bearing installation.

Then, maybe improper selection of bearing clearance is a reason.

Finally, unreasonable lubrication will also influence the bearing because there may be too much oil or too little oil.
