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 aur 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 tool screws when sockets become worn. Don''t use wrenches with rounded corners. Don''t use a screwdriver to spread collars, or a hammer kit 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.
