Taper-Lock bushings and hubs are flangeless for clean, stabilize overhung loads. Used in flush mounting compact application for mounting sprockets, sheaves and pulleys. They are engineered split through the flange and gradual taper that use screws to tighten on the shaft and provide a true clamp fit on the shaft that is the equivalent of a shrink fit with an 8° taper and a flush-mounted design with no protruding parts providing secure locking and elimination of wobble. Taper-locking bushings have evenly spaced installation and removal holes. They are highly effective in high-torque applications when installed correctly.In addition, Taper-Lock bushings are available in popular sizes and bores standard and metric for a more precise fit.
