Is it possible that the wear is caused by the oil seal or the bearing cage?
Suspicion of wear; lubricant has been replaced. It has been running for some time and is still under testing. If it really doesn’t work, just replace it
It should be related to the copper components; identify all the components of this material in the equipment, and analyze them to rule out possibilities or conduct inspections
