Quick disconnect bushings, also referred to as QD bushings, feature a split-through flange that makes them easier to install and remove. They also have higher holding power because of the cap screw that can be tightened.

Installation and Removal of QD Bushings:

QD or “Quick Detachable” bushings are used on sprockets, pulleys, and pulleys to increase the clamping force beyond standard boring-to-size products that are locked to the shaft using only the keyway and set screws.

These bushings also have the added advantage of being able to mount in reverse, eliminating the need for additional screws. However, because the flange must be inserted from the side, it is more difficult to install.

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 flange of the bushing. 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 pocket or another part against the flange of the QD bushing to break the cone grip.

2. Loosen the set screw and slide the QD bushing from the shaft.

QD Style Taper Bushings:

Type QD bushing, also known as Quick Detachable bushing, is a mechanical drive connecting component used throughout the industrial power drive and agricultural industries of sprockets, sheaves. These bushings feature a flange on one side and a fully split taper on the other. They are precision machined so that they fit easily with compatible sprockets and pulleys of the same coaxial size, without the need to hold down the shaft to connect.

These bushings are available in a variety of styles and are designed for quick and easy installation and removal. They can be flanged or unflanged and are available in a variety of sizes. They can also be drilled to accept a wide range of bolts and screws, making them a common component for many applications.

 

We are one of china’s best qd bushing manufacturers. We can offer a wide variety of qd bushing and different qd bushing dimensions.We also can provide some qd bushing size charts and qd bushing torque specs. We have exported our products to clients around the world and earned a good reputation because of our superior product quality and after-sales service.

We warmly welcome customers both at home and abroad to contact us to negotiate business, exchange information, and cooperate with us!

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.
