Question: What are the minimum and maximum shaft gaps for a coupling?
Answer:The user is basically asking about the minimum and maximum shaft penetrations of the coupling. On our product pages we call out the max shaft penetration for all of the couplings we make. In the case of something like a bellows coupling, it's going to be something like half the length of the coupling less a little bit to accommodate for misalignment. On something like a jaw coupling it's going to be limited by the hub length so the shafts don't interfere with the spider. The minimum shaft penetration is not something we currently post on the website but is coming soon. For clamp style couplings, the shafts must go all the way through the clamp cut. For set screw style, the chamfer on the shaft must penetrate through so the set screw doesn't interfere with it.
