Buyer's Insight: Bearings

We are in the process of having the front fork reassembled after prep and paint. I mentioned to Christopher Markley that we were replacing the bearings and bought replacements already. On a couple occations Christopher really encouraged me to replace the front bearings with "sealed" bearings -- a nice modern convenience and when I finally decided to return the bearings I bought Christopher turned me on to our local SKF bearings dealer (who knew we had such a thing!). Bottom line folks, find your local (or nearest) SKF dealer and purchase your bearings through them. On average bearings at the scoot shop where I made my purchase at were between 35-50% cheaper (yes, 50% cheaper for the same exact bearing!) at my SKF dealer. Because it was so much cheaper I upgraded to the top of the line sealed bearings and still managed to save $8 total (after my 20% restocking fee at my scoot shop, which is NOT local -- it's on the other coast -- and my bearing shop is right here in town).

There are three levels of bearings I looked at.

1) Open bearings -- lowest grade and cheapest
2) Shield bearings -- mid grade with steel protectors around the bearings
3) Sealed bearings -- highest grade (no containments may enter the bearing, but you can not re-greese it either. These bearings should be good for 25 years) These bearings are a slight overkill.

If you do not have a local SKF dealer, check out:
Applied Industrial Technologies

Damn hind site is 20/20 . . . I should have replaced my rear bearings from here as well (no need to go sealed -- that's overkill on the rear)

I truly believe that you will have a SKF dealer in San Diego, that's where you are right? I'm from S.F.

my local scoot shop and just get new ones. But if the skf ones are considerably cheaper, I'll buy from them.

Lol, I found this sitesearching for skf bearings, luckily Martin at sorted me out. Gawd knows what I'd have found looking for dodge or NKE bearings.
