I'm finding it hard / expensive to find replacement roller bearings for my lathe's QCGB, can find ball bearings the right size for a fifth the cost and wondering whether it'll make a difference that matters!
The original spec' is Hoffmann RLS10LL, 1" ID, 2.250" OD, 0.625" width roller bearings with unflanged (demountable) outer races to allow ease of assembly - axial location is taken care of by pairs of opposed taper rollers. the RLS10LL allows some axial movement for thermal expansion also.
Essential question, is replacing the rollers with available ball bearings going to affect the performance of the QCGB?
LJ1 / RLS8 ball bearings are the right sizes (and relatively affordable), BUT aren't demountable (as far as I can tell), any recommendations for a demountable bearing with the right dimensions if it's impossible to reassemble the QCGB with built-up bearings? Less costly demountable rollers?
Thanks in advance for any suggestions / yes do it / bad idea!
