Thought I would post these pics here rather than intrude on BooG's original post anymore.
Here's a few pics showing the OEM swing arm bearing next to the All Balls replacement bearing.
All Balls state thatevery thing needed to replace the swing arm bearings in your K bike are in the box! Yeah right, what they don't say is you need to go to your local machine shop and have a spacer fabricated tomake there bearings work. As All Balls did supply a bigger seal that was suppose to act as the spacer(sorry cant find that now) but that was totally useless.
So if you need to change the swing arm bearings, I recommend spendinga bit more dosh for some quality not these cheap All Balls crap.

They look like Paralever rear joint swingarm bearings to me.

The outside diameter looks smaller or is that just camera tricks. The paralever bearings are smaller OD but I think ID is the same.

The dimensions are the same as the Fag, it's only the width that's different.

Its not what I thought it was then.
I am not a fan of those swingarm roller bearings, they don't take the load well when not rotating. You would be a lot better off with an angular contact ball race but they cost more.
