- Single row ball bearing to fit BTH KD1 competition magnetos (as fitted to Norton camshaft engines). I believe this bearing also fits other similar BTH single cylinder magneto's, i.e. standard KD1 and MH1 models
Good quality NSK brand bearing.
Note: when fitting new bearings in a magneto body, they should be fitted with a special star type paper washer that insulates the bearing from the body. We also sell these gaskets, as shown in the photo - Item 0178
