try south shore bearing in quincy they may have it in stock

 

I used a NTN 6304-2RS bearing in my 80mm pulley. My proir post was wrong. I checked my ebay account to ses what I bought and it was the 6304. I will correct my prior post.

 

Acamato - thanks for checking that out. I should be good to go. I went with a Japanese bearing because it was the best brand I could find through Amazon. It was only a few dollars more than the cheapest ones, but all of the lower priced ones had bad reviews. Most of them were from Rover owners complaining that they quickly failed in their idler pulleys!
