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 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 assembly or disassembly later on, and to have some adjustment to airtooldrills a connection during the lifetime of the component. Traditional shrink fit and press fit methods of attaching components to shafts don''t 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 airtooldrills of keyways is eliminated. Smaller shaft sizes, in turn, mean smaller bearings and other mating components can be employed.

Mark/B-LOC: Aside from improper installation, the most common oversight we see is a failure to accurately quantify applied dynamic loads or, when this is not possible, to base selections on an appropriate safety factor. Before selecting a device, consider all types of loading acting on system components and either determine their peak values or apply a safety factor that is right for the job.Jeff/KTR: The majority of problems we''ve seen stem from improper selection. The dimensional tolerance of the hub and shaft must be correct to effectively maintain peak torque transmission of the clamping elements. It''s also important that the hub material be thick enough to prevent breakage when the elements are installed.Keith/U.S. Tsubaki: Hub dimensions that don''t airtooldrills match the manufacturer''s requirements can reduce holding power and lead to potential problems. Tightening the unit''s locking bolts by "feel" or with crude air tools may create an unpredictable torque capacity.
