Not so expensive purchased from a tool shop. You can pay more and get a better looking piece but if both meet the same accuracy you can save the money for the polish and polishing wheels.

As an example, if the overall bearing was machined to be .499 of an inch. It will probably vary and be .499 to .4989 or .4988. (Hopefully it will be at least this tightly machined!) You just have to measure the whole length to see where the low point value is on your particular bearing.
Then polish the entire bearing to that low point. We do this for crank shafts all the time. Micropolishing = horsepower and performance longevity. That and main bearing alignment is critical as well.
