Taper-Lock Bushing 4040-3-1/4"

These hubless steel bushings mount flush into your sprocket or pulley, creating a slim profile without protruding screws. Designed for use with taper-lock coupling sprockets of the same style, they secure firmly as the included set screws tighten, gripping the shaft and drawing it into place. With an 8° taper, these Taper-Lock Bushings are available with either a standard ANSI keyway or a shallow keyway. Bushings with a standard ANSI keyway are sold without a key, while those with a shallow keyway include a key.
