Jeff/KTR: Prevent rust and make sure fasteners are tightened to the specified torques after a minimum operation time. Replace the device if it starts to slip. Reconfirm the selection, and be sure to check the dimensions and surface finish of the bore and shafts.Doug/Zero-Max: Keep the connection screws properly torqued for maximum holding forces, and use a connection with a minimum number of adjusting screws.Jim/Stafford: Replace socket screws when sockets become worn. Don''t use wrenches with rounded corners. Don''t use a screwdriver to spread collars, or a hammer to move them along a shaft.Keith/U.S. Tsubaki: Higher quality locking devices are practically maintenance-free. There is no need to periodically retighten locking bolts or replace the unit, even in high-vibration applications. End users can extend service life even longer by keeping exposed surfaces clean and corrosion free.

* 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 atkantaairtools 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 atkantaairtools 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.
