The bore is the shaft diameter, so it is the one dimension you cannot change: pick the bore first, then decide the type from the load and speed, then the outer diameter from the housing you have. If the housing is fixed, filter by outer diameter in the product center. For fits and shaft tolerances see the fit recommendations.
