Need Clarity on runout issue
Need Clarity on runout issue
(OP)
Hello,
I have a tolerance on a motor shaft that needs clarity:
the dim is now as follows: (metric)
single-arrow runout: "0.0381"
position referenced to the housing boss: "Dia 0.0381"
Does the positional tolerance restrict the runout to be within a 'cylinder' of Dia 0.0381 along the entire length?
Thanks

Also, with a motor shaft, it would be spinning. Wouldn't total runout be more appropriate? I'm not sure without seeing the part.

Total runout would make for an extremely costly shaft. I've seen pump shafts with multiple bearing and element diamters having runouts of .0005" to grind centers. If this was total runout it would mean that the entire surface would have to fall within this tolerance band.
I think Kim needs to give us more information to correctly answer her inquiry.
