The NSK catalogue gives a number of options "Single, Back to Back, Face to Face, Tandem". As I want to use the original bearing mounts from my RF30 (meaning they will be separated by a divider in the housing) my next issue is what is the correct pairs of bearings to use and what their separation should be.
Can anyone advise ????
