Expert Response Provided by Chuck Schultz. Designers frequently have to mount bearing inner races on surfaces that are interrupted by gear or spline teeth or the "runout" area of the cutters used to make those teeth. Bearing manufacturers have their own policies on how much support a particular bearing needs so your best information will come from them.

I say "try" because with apologies to Yoda, some situations will not quite comply with the rules.
