swing arm bearing replacements

I'm going to do the swingarm/unilink service again and was thinking I should go ahead and replace the swing arm bearings this time. (I have handling issues, and a tiny bit of vertical play there). I was wondering if I should use tapered bearings and if so where to get them. I've done a few searches. I'm not turning up much on swing arm bearings for this bike--not anyway tapered bearing. I think I'mm finding the original Kawasaki "needle" bearings.

I know next to nothing about bearings, so I don't know if there are standard sizes that are interchangeable or if they are very bike specific.

Can any of you point me in the right direction?

I'm going to be replacing bit by bit all of the bearings on the bike--wheels, steering head, and swing arm but the swing arm bearings are the ones I'm not finding.

Thank you.

They are needle rollers and if intact, just require cleaning and re greasing, Replace only fo damages

thank you. My clymer is telling me it's kind of hard to tell if the swing arm bearings are worn out or not, and because I've got a lot of miles on the bike (60K) and because I'm dealing with a bit of vertical swingarm play, I thought I'd just play it safe and put in new ones while I'm doing a lot of other stuff. I will order the Kawasaki needle rollers unless some one can tell me of a higher quality replacement.

I seriously doubt there is anything better than the OEM bearings out there.

Thanks. I was thinking because replacement bearings for the steering stem are often tapered and supposedly better than OEM that maybe there was a similar option of the swing arm. But increasingly it looks like this is not the case.

Mcmasterr carr is uasually my first stop for anything hardware related, if there is a screw, nut or bearing made they should have it. You will need all of the measurments.

Thank you, sir. I plan on taking it apart this week. I will check the shaft, too, when I'm cleaning up everything.
