* How important 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 than calculating the required torque. Centering requirements, ease of installation, and the 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 airtoolssancblaster availability.Vic/Rimtec: Avoiding keyways improves shaft maintenance. Using keyless clamping locking devices or shrink discs makes it easy to change parts.

Component interactionsHow do locking device choices affect other areas of the machine or system?Andrew/Whittet-Higgins: The precision and life expectancy of a bearing, power transmission, or modern assembly is only as good as the precision of the individual components and the care in which they are put together.Blair/Ruland: It''s important to look at where and how the locking device is being used and whether adjustments may cause problems. Locking devices in general are not easy to remove and replace. Because of this, it may be advantageous to have necessary adjustments done from another section of the machine.Doug/Zero-Max: When using keyless locking devices, there are fewer application problems because there is no keyway failure or fatigue. Connections without keyways also have smaller shaft diameters, translating into shaft material cost savings. The single screw type can be tightened and repositioned many times without component wear or machine downtime.
