I'd like to replace the spherical bearings in my JRZ top mounts. Trying to find measurements or a part number online has come up with nothing. I don't want to call JRZ as they are probably selling them with a substantial markup. Any info on sizing or where to source from would be appreciated.

you could always take them in to your local bearing wholesaler they can probably eyeball them and tell you what it is. im picking they are a standard size spherical as JRZ will do that to keep manufacturing costs down.

Best bet is to pull it out and measure it. Standard size would be nice but if its like Ohlin there's 2 sources I've found, one is Ohlin and their authorized repair vendors, other is bulk from china via allibaba. The former being $80 each and latter being a min order of 100. I feel like I should buy a min order at some point and just sell them for ~$5 over because $80 for those bearings is terrible.

dallas, what size are ohlins bearings? The rears more specifically..

Front and rear are the same, but they are:

ID:18mm
OD: 33mm
Ball Width: 20mm
Race Width: 16mm

IIRC, you can find the 18mm ID bearings no problem, but not with 33mm OD.

yeah, it is a weird size...

If I were you I would cut some new top mounts with more common 18x35 mm bearing.

looks like they are 18x35mm. Any recommendations on which to get? Aurora? There are no part numbers stamped on these.

I use Fluro, but I am in EU and Fluro is german... Try Aurora, or search for Fluro motorsport units if you can find them in the USA... as far as I can see, https://mdmetric.com/ sells them

Called Pegasus and gave them my measurements and they are claiming its an odd size. They had nothing in their inventory to match.

You gotta search outside the US for those odd bearings. Found a place in UK that has a match for the size.

That was quick.

Thanks for the links, guys. Lets see how long shipping will be from the UK.
