QD Bushings | Quick Disconnect Bushings

QD bushings are utilized throughout the industrial power transmission and agricultural industry for various sprockets, sheaves, pulleys, and synchronized drives. They are designed for easy installation and easy uninstallation; they are also commonly referred to as quick-disconnect bushings. QD bushings can help conventional mounting with the flange outboard and reverse mounting to where the flange is inboard and utilize a single split that extends through the entire bushing length. Our QD bushings interchange with other brands and are made from high-grade steel precision machined for perfect application fitment. QD bushings' benefits over different styles include; ease of installation/ uninstall, superior holding power, and extreme strengths. We stock all the standard sizes of QD bushings and supply custom QD bushings upon request, including stainless steel ones.

QD Bushing Installation and Removal Instructions

Standard Mounting 1. Be sure that the tapered cone surfaces on the bushing and inside of the driven product are clean and free of oil or anti-seize lubricants. 2. Slide the QD bushing on the shaft, flange the end first, then assemble the key. 3. Position the QD bushing on the shaft. Tighten the set screw over the key (hand tight) with a standard Allen wrench. Do not use excessive force. 4. Slide the large end of the sprocket, or other part taper bore into position over the cone, aligning drilled bolt holes in the sprocket or other part with tapered holes into the bushing flange. Then assemble the pull-up bolts and lock washers. 5. Tighten pull-up bolts alternatively and evenly to the tightness indicated in the torque table below. Do not use extensions on the wrench handles. There should now be a gap between the face of the sprocket or other part hub and the flange of the QD bushing to ensure a good cone grip and press fit. Caution: this gap must not be closed. Dismounting 1. Remove all pull-up bolts and screw them into tapped holes in the sprocket or another part against the flange of the QD bush the ing to break the cone grip. 2. Loosen the set screw and slide the QD bushing from the shaft.

Applications of QD Bushings

QD Bushings feature a split tapered flange with the split central to the flange and taper. They are used on sprockets, sheaves, and pulleys where more clamping force is required over standard bored-to-size bushings. Bushing products are widely used in compressors, fans, air compressors, pumps, petroleum equipment, conveyors, grain machinery, agricultural machinery, air conditioning, and ventilation equipment.
