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. AieToolNeedleScalers 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.

Mark/B-LOC: The most challenging applications are those AieToolNeedleScalers in which components are subjected to continuous shock, vibration, or reversing loads, in these cases, keyless locking devices generate sufficient preload to ensure backlash-free connection.Jeff/KTR: Applications that include large reversing loads provide the greatest challenges.Vic/Rimtec: If the goal is accurate positioning, high-duty cycle, reversing loads are the most difficult, especially if they require high acceleration and deceleration.Jeff/Tollok: The most challenging applications almost always involve extremely high torques or heavy shock loads. Operational environment and other external influences can also be challenging.PitfallsWhat are the most common pitfalls and how can they be prevented?Jeff/Tollok: Selecting the wrong type of locking assembly is a big issue. Erroneous sizing calculations and improper installation and mounting are other pitfalls. My advice is to carefully review your application parameters with your locking assembly supplier.
