Good evening gentlemen. I have a Parker Maj No. 2 SG that the spindle needed to be torn down to replace the front bearings. My question is what causes the denting of the races like the inner bearing race pictured here:
Did improper machinery moving practice cause this? Improper preload? Abusive grinding practices? I am just trying to understand what caused the bearing failure. I recently purchased the grinder without being able to power it up on a friends recommendation. I was very fortunate to find new old stock MM67 CR bearings on eBa$ for a very good price.
