easy question, is there a standard iso fitting bearing/spindle turntable?
Like H7/f7, G7/h6, J8/h7?
Standard sintered bronze bearings are all H7 fitting and I think that's to big...
thanks

I waited for somebody in industry to post and say------yes ! my company produced/produces an iso standard sintered bronze bearing in our turntable production line --doing it for decades .
As nobody has replied ---yet I can only give an example of my bearing in my Dias --engineered by Nottingham Engineering England --- no not China etc ( I spoke to the company director by phone decades ago )
and it is not iso standard .
Do I hear the click of posters worldwide pulling off their turntables and measuring the bearing dimensions ??
So until somebody posts saying --- no !!!! I am wrong 90 % of the worlds turntable bearings are standard iso ---easy answer----no.
For the record many upmarket turntable manufacturers in the past took pride in their innovative engineering designs and that included their own take on bearing design , mine is not standard but I do have to give the bearing special oil ( no not your automobile oil ) but stuff for high pressure use.
Downmarket turntables would save money by using a standard iso bearing in their production line but I take it you are talking of QUALITY turntables ----yes ?
