Identify the materials that each subcomponent of the bearing

Identify the materials that each sub-component of the bearing is made out of. Which of these is most likely to wear? Speculate on what you expect as a wear pattern (i.e., what does the bearing look like when it is partially worn out) and eventual mode of failure (what will eventually fail first)?

Outer Ring Top View of Bearing Retainer Inner Race Bottom View of Bearing

Solution

third figure is of crown retainer which is made from molded or machined plastic including polyamide , polyacetal

Inner race and outer race is made from same material it is made from plastic material for higher load it is made from steel and heat treatment process can be done and next machining work will be done by grinding

when a bearing wears out it is usually a case of inadequate lubrication , and outer race will wear out fast once the races has worn through this layer rapid wear occurs to the soften metal below this is called spalling .this kind of damage causes the metal to come off flakes
