Does anyone know what the part numbers are for the bearings on all the rear suspension pivots please?

I’m aware that I should get enduro max bearings.. why is there a big difference in price between the kits sold by mbbearings betd and Katec on eBay? Assuming there all max bearings..
Is katec kaesae?

Thanks

Katec is kasae. I got my trance bearings from mtbbearings. They are proper job.

I checked out mtb bearings…I noticed they mention abec ratings.. I thought that was irrelevant to suspension pivot application?

Anyone use mbbearings? Assume the Enduro bearings are the ones to go for?
Noticed that the bearing numbers are on the seals..
638000VRS
6900VRS
6902VRS
6802FRS

What does VRS stand for? Can’t find t on any bearing suppliers site..

RS is rubber seal not sure on V
