Dennis, you can wear that bearing as an armband around your biceps. That's why
the cost is so extreme.... those are HUGE!!!!

Apparently there is something odd ball about that particular bearing.
A bearing like that should be no more than $10-$15 ea retail.
It may be a larger O.D. or a different width may be more standard.
Maybe shields instead of seals, etc., may get you to a standard price
bearing. You will need to talk to a good salesman at a bearing supplier
to get similar bearings and prices. Just tell them the ID, OD, and width
you need and that it needs to be sealed or at least shielded.
