Good afternoon and season's greetings all.
I've been looking for a definitive statement for the shaft size limits for standard taperlock bushes. I have a 3020 bush on a nominal 48 mm shaft which measures 48.01 mm and it seems awful tight to get on.
I want to fit a flywheel to the other end of this shaft, which would involve a 2012 bush, and 48 mm is at the very top of the range of sizes for a 2012 bush. This end of the shaft is presently 48.04 mm dia. Do I need to get nearer to the nominal 48 mm dia?
I've found a passing reference in the Fenner catalogue indicating that (quote) "accommodates shaft limits of +0.051/ – 0.127 mm". My shaft sizes fall inside these limits, but this gives no indication that the shaft tolerance might change with shaft size as I would have expected.
As ever, my thanks for the expertise.
Any ideas?
PS (edit) It always helps to know the application. I'm making a simple stone crusher, as I have a large pile of useless stone and several boggy gateways. And I want to clear the stone but am too tight fisted to pay someone to haul it away. So I thought the last lockdown would be usefully invested in making a gadget.
I'll add a link to a Youtube video of its very first outing to a separate post,
