Qd Bushing

qd bushing

QD bushings (inch and metric sizes) have a flanged design and feature a 4° taper with conventional or reverse mounting. They are stocked in popular finished bore sizes and minimum plain bore for custom reboring.

Use a tapered or QD bushing from Grainger with sheaves, pulleys, sprockets and many other power transmission applications. Flanged quick-disconnect bushings feature a completely split design to help provide easy installation and disassembly. A tapered bushing with straight edges uses an internal screw to help drive the bushing into the shaft, while a split taper has a flange and a key on the bushing to help provide more drive.

USA Roller Chain and sprockets is a one-stop shop industrial power transmission supply facility that is focused on quality, value, and great customer service. We also have a highly-trained expert staff to answer any questions that you might have.

1. Be sure that the tapered cone surfaces on the bushing and the inside of the driven product is clean and free of oil or any anti-seize lubricants.
2. Slide the QD bushing on shaft, flange end first, then assemble key.
3. Position the QD bushing on the shaft. Tighten the set screw over the key (hand tight) with a standard Allen wrench only. Do not use excessive force.
4. Slide the large end of 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 flange of bushing. Then assemble the pull-up bolts and lock washers.
5. Tighten pull-up bolts alternatively and evenly to 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 insure a satisfactory cone grip and press fit. Caution: this gap must not be closed.

1. Remove all pull-up bolts and screw them into tapped holes in sprocket or other part, against flange of QD bushing to break the cone grip.
2. Loosen set screw and slide QD bushing from shaft.
