Mark/B-LOC: Using keyless locking devices in place of keys, splines, and shrink or press fits typically means savings in other areas of machine design, such as smaller shafts and bearings and simplified machining. PT components can be positioned anywhere along a shaft without regard to keyway Air placement or access for mounting or removal tools. Keyless locking devices require only torque wrench access for installation and adequate hub strength of mounted components.Carl/Ringfeder: The main reasons to use locking devices are to eliminate backlash in a connection, eliminate troublesome Tool assembly or disassembly later on, and to have some adjustment to a connection during the lifetime of the component. Traditional shrink fit and press fit methods of attaching components to shafts don''t Cgisels allow for easy adjustment or removal. Some connections will never be loosened; so attaching them with a locking device only makes sense when using it facilitates assembly. Employing keyless locking devices in the design means smaller shaft sizes because the stress concentration factors of keyways is eliminated. Smaller shaft sizes, in turn, mean smaller bearings and other mating components can be employed.

Andrew/Whittet-Higgins: One pitfall is not allowing the Air needed spacing in the assembly housing. If the components are not locked together properly, the machinery can fail prematurely. A second pitfall is assuming that a particular torque measurement for one component is correct for the entire assembly.Jim/Stafford: * Using a set-screw collar on a hardened shaft. The screw does not "set," and holding power is greatly diminished.* Using a set-screw collar on thin-wall tubing, which can permanently distort Tool the tubing.* Specifying too thin a width on a clamp-type collar, leaving it too weak to resist distortion when the clamp-screw is tightened.* Specifying too thin a clamp-slot on threaded shaft collars where the collar must flex more in order to adequately clamp onto the threaded shaft.
