I just picked up a 6205 and 6303 double sealed wheel bearings for my Kaw Zephyr 550 for $4.52/ea and $5.03/ea at a local Fastenal that had them in stock. I know some companies that do electric motor rebuild may also stock the correct numbered bearing for your front or rear wheels, and others for that matter, should you need them. I still need to look out for some decent priced seals some place, but not right now.

The cool part - all three rear wheel bearings can be had for under $16.00. If your Fastenal store doesn't have them in stock they can get them in, but they may have a shipping charge if special order. Now if I can find a decent source for the seals.

I did a search on the Fastenal.com site using "ball bearings 6205" as the search. They show a number of parts with differing prices, but I got the lower priced ones, which will work fine based on load capacity and rpm (way above the bike capability).

Just figured I'd let you know...

 

Good to know, you can also use your local motion control store that supplies belts, bearings, shafts, gears to cross reference. Get your verniers' out everyone! and lets go shopping.
