Bushings and hubs are available in many variants and offer specific advantages in power transmission applications from automotive to papermaking. Tapered bushings feature a split, flangeless design with a tapered outer diameter that matches the tapered bore of a pulley, sprocket or clutch. Installation with the FX switch case is simple by sliding the case into place and tightening it with the clamp screws. QD bushings feature split, heavy-duty flanged construction with a tapered outside diameter that matches the opening of a pulley, sprocket or clutch.
