I have found this http://www.vsource.org/VFR-RVF_files/BBearings.htm on the internet regarding bearings. But to me the list is not so good. What I need is all the international bearing codes like 6004 2RS or 61903 2RS etc etc (there's only a few in the document above). These codes are used by SKF, FAG etc. Can somebody please help me out? Maybe a person who has replaced all the bearings and written a note on all the bearing codes? Example: The sprocket carrier bearing is a DF 0768 LU with the following dimensions: 35x55x20 mm. What sort of bearing is that and does it have another code? Has somebody changed this bearing and can tell exactly which one it is? Regards Lucas Jensen
