I need to ad some bearings to the idler on my ZTZ99. They look to be 8mm od 4mm id and about 1.5mm wide. I'm not having luck finding them.
Thanks

Thanks that is just what I needed. They have some other sizes that give me options on improving what is there.

Can look at boca bearings too. Depending on what you want to spend they'll custom make bearings for ya as well.

I second Boca. They have everything and ship fast.

Bottom line is, if you're going to the trouble, buy quality bearings, not some cheap repacked crap.

VXB Bearings. They have EVERYTHING. I like them even better than Boca. Their site is easier to use and find what you are looking for also.
