rij Posted March 7, 2010 Report Share Posted March 7, 2010 (edited) Hi, This is probably a daft question, main bearings have failed on 200cc rev3 2001 are they ment to be plain ball bearing open cage 62/30/16? the reason i'm asking is because on a website based in church stretton they have pictured a sealed bearings with a type of metal seal? didn't know if this was just a stock photo? also whats the best quality bearing manufacturer? fag skf koyo? Thanks rij Edited March 7, 2010 by rij Quote Link to comment Share on other sites More sharing options...
kasob1964 Posted March 10, 2010 Report Share Posted March 10, 2010 Hi, I replaced the main crank bearings on my 2002 Beta Rev 3. I purchased the bearings from the main UK importers Lampkins. I do not remember the make but was surprised when they arrived because they were sealed bearings. Quote Link to comment Share on other sites More sharing options...
davllan123 Posted March 10, 2010 Report Share Posted March 10, 2010 I bought some from Lampkins for my 250 and gave to my local shop to fit. They removed the metal bit before fitting. work great. Quote Link to comment Share on other sites More sharing options...
