Additional Information

This type of sprocket is used in applications where higher working loads are prevalent and high clamp loading on the drive shaft is desirable. Sprockets with tapered bushings will fall into the QD, Split-Taper or Taper-Lock family. QD bushings are flanged and most commonly utilize large anchor bolts around the circumference of the flange to retain itself to the sprocket. However, this style of bushing is also available in a weld on hub configuration. One of the primary advantages the QD bushing offers is its ease of installation and removal. It also provides superior clamp force and aligns the sprocket 90 deg to the drive shaft to assure proper alignment.
