The bearing rolling elements are worn, showing a plum blossom pattern

2011-12-09View Original

Thread Content

One of the company’s pumps was experiencing excessive vibration. Upon disassembly and inspection, it was found that the rolling elements of the thrust bearing were worn; the pattern of wear resembled a plum blossom, with seven points arranged in a regular plum-blossom shape； Some have another such mark in the 180-degree direction; I’m not sure why this happens. Please analyze it – what could be the possible reasons? Has any senior encountered this situation? Please share

It would be best to include a diagram; that way it will be clearer for everyone to see!
