I have a shaft running in a tubular housing supported by 3 bearings, the two outboard bearings are 6809 LU by NTN and the center bearing is a 61809 RS with no manufacturer noted. These are all58mm OD,45mm ID and 7mm wide bearings. When pricing them, there is a big difference in the cost, and I was wondering if there really is a difference? Thanks in advance.
