stout5574,
have someone you know that is good with vernier calipers,come over. (give him a can of beer,,haha),,,,simply have him caliper the inside,(ID) of the housing were the bearing was taken out of.next have him caliper the shaft. With these two simple deminsions you can start calling any bearing specifc supply place and they will be able to come up with both the bearing and seals for your cutter. FYI. in this part of the country with the economy so lousy almost all of the bearing ONLY warehouses have shut down its sad to say,,,so like someone else stated you may have to go to a NAPA store,,and hope you get a guy that is willing to dig through their bearing/seal catalog,,and find ther untis,,,you need.
Good Luck,
BC
