* How important Air is run-out of the installed component?* What are the tolerance or precision requirements of the specific industry you are in?Keith/U.S. Tsubaki: Proper selection requires more Tool than calculating the required torque. Centering requirements, ease of installation, and the Cpuplers forces the unit applies to the shaft and hub also apply.Jeff/KTR: Precisely determine the hub location required for the desired application. Evaluate the radial and axial position and the amount of space available for the locking device, and then select the type of device needed.Andrew/Whittet-Higgins: Choose the right device, taking into consideration static and dynamic loading, assembly, maintenance, misalignment, price of the full assembly, and availability.Vic/Rimtec: Avoiding keyways improves shaft maintenance. Using keyless clamping locking devices or shrink discs makes it easy to change parts.
