* Using the face of a clamp-type collar as a bearing surface in a rotary application. The saw slot can quickly abrade the surface rotating against it.Doug/Zero-Max: Improper tightening of multiple screws can cause bushing slippage. Axial movement of the bushing on the shaft when tightening can cause some alignment loss. Some connections feature a single tightening screw flint can be torqued if necessary for proper clamping force.Best practicesWhat are considered "best practices" when designing with locking devices?Carl/Ringfeder: Aside from the obvious design parameters, engineers should ask the following questions:* What are the application requirements of the device?* Is the locking device only used to simplify installation or is adjustment, removal, or maintenance necessary?

* 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, airroolshistory 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 availability.Vic/Rimtec: Avoiding keyways improves shaft maintenance. Using keyless clamping locking devices or shrink discs makes it easy to change parts.
