A line of keyless hub locking assemblies is designed to improve the connection between a drive component and shaft by eliminating problems of backlash, as well as the limitations of keyway connections and QD-style and tapered bushings. To do this, the locking assemblies form a shaft-to-hub friction connection that relies on concentric surface pressure. Available in both English and Metric sizes and a wide variety of styles — in all, there are 232 sizes and over 1,000 combinations of styles and sizes — the assemblies can be used to fasten gears, sprockets, and other drive components to a motor-driven shaft. Common uses include timing and conveyor pulleys, sheaves, indexing mechanisms, levers, cams, motors and hydraulics, clutches, brakes, and flange couplings.
