Hi,
I'm making up a rotary indexer. In the headstock build i'm using a ER32 collet shaft extender. The shaft is 32mm OD and bearings 32mm ID but they are too tight a fit at the moment to slip on.
The difference as measured by a collegue (shouted across the room) is 5000th of an inch, or 0.0127mm in my world.
Will heating the bearings allow me to get these on or should I be looking at getting the shaft turned down, or another method?
ThanksLast edited by marbles; 28-11-2018 at 12:05 PM.
