The original sheave and pulley installation system developed to facilitate installation and substitute of components.
The QD (Quick Detachable) design offers both conventional (flange outboard) and invert (flange inboard) mounting configurations.
1. Be certain the tapered cone areas of the bushing and the within of the driven item are clean and free of anti-seize lubricants.
2. Slide QD bushing on shaft, flange end initial. Assemble key.
3. Position QD bushing on shaft. Tighten established screw over key “hands tight” with standard Allen wrench only. Do not use excessive force.
4. Slide huge end of sheave or sprocket taper bore into position over cone aligning drilled bolt holes in sheave or sprocket with tapped holes in flange of bushing. Assemble pull-up bolts and lock washers.
NOTE: Install M thru S bushings in the hub to ensure that the two extra holes in the hub are located as far as possible from the bushing’s saw cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque desk on back. Usually do not use extensions on wrench handles. There must be a gap between your face of the sheave or sprocket hub and the flange of the QD bushing to insure a reasonable cone grip and press fit.
CAUTION: THIS GAP SHOULD NOT BE CLOSED.
Make use of a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and many other power transmission applications. Flanged quick-disconnect bushings feature a completely split style to help provide easy installation and disassembly. A tapered bushing with directly edges uses an internal screw to greatly help drive the bushing in to the shaft, while a split taper includes a flange and an integral on the bushing to greatly help provide more drive.
QD bushings (inch and metric sizes) possess a flanged style and show a 4° taper with typical or reverse installation. They are stocked in popular completed bore sizes and minimum plain bore for custom reboring.
Many people make reference to both types as a “taper lock” because they both utilize the tapered wedging action to lock to the shaft. The taper bushing, with it’s straight sides, runs on the set screw to drive the bushing into the bore of the component being installed (sheave, sprocket, etc.). Be qd bushing china careful when installing these screws. The holes with threads on the bushing are for removal just. Also be aware that the looks of a flange externally of the bushing doesn’t indicate it’s a QD style. Split Taper bushing also has a flange, and the two are not interchangeable. The QD design includes a split that proceeds through the flange. The Metal QD (Quick Disconnect) Type bushing offers flexible and easy installation while providing exceptional keeping power. QD Bushings are used thought out the industry offering comfort and design versatility. They are precision machined of quality Steel and are installed by tightening several cap screws. This draws the bushing in to the taper bore of the product which compresses the bore of the bushing. QD bushings are often removed utilizing the cap screws as jack-screws. Double drilled holes are furnished in QD Bushings permitting installation of product in the conventional or reverse positions. This allows cap screws to become installed through product hub or bushing flange whichever is usually most convenient. A significant benefit in set up, cap screws are often inserted from the exterior where they are easily accessible. QD Bushings can be found from share with all well-known bores within the number of each size bushing.
QD Bushings feature a split tapered flange with the split central to the flange and taper. They are applied to sprockets, sheaves, and pulleys where more clamping power is necessary over standard bored-to-size bushings. Quick-Disconnect Bushings are essential for mounting v-belt drives, synchronous belt drives and roller chain drives.

Our immediate supply chain to Martin Sprockets factories gets a wider range of QD Bushings delivered at the right time at the proper price.
Taper bushing are trusted together with sprockets, v-belt pulleys, timing pulleys, coupling and other mechanical parts with taper bore connections.
Taper bushing series are made from high quality engineered materials with great tolerance. The feature can be easy to use and needs no additional alteration. These bushings can fit almost all kinds of assemblies and sizes. They will be the best choice in style for mechanical connections.
No costly re-boring: complete selection of both metric and imperial available.
Standard range matches up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete short reach range offered, for compact lightweight assemblies & Clean, Compact Design.
Simple installation and removal.
The initial sheave and pulley installation system developed to facilitate installation and alternative of components.
The QD (Quick Detachable) design provides for both conventional (flange outboard) and reverse (flange inboard) mounting configurations.
1. Be certain the tapered cone areas of the bushing and the inside of the driven product are clean and free of anti-seize lubricants.
2. Slide QD bushing on shaft, flange end initial. Assemble key.
3. Placement QD bushing on shaft. Tighten established screw over key “hands tight” with regular Allen wrench only. Do not use excessive force.
4. Slide huge end of sheave or sprocket taper bore into placement over cone aligning drilled bolt holes in sheave or sprocket with tapped holes in flange of bushing. Assemble pull-up bolts and lock washers.
NOTE: Install M thru S bushings in the hub to ensure that both extra holes in the hub can be found as far as feasible from the bushing’s noticed cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque desk on back. Do not make use of extensions on wrench handles. There should be a gap between the encounter of the sheave or sprocket hub and the flange of the QD bushing to insure a reasonable cone grasp and press fit.

Many people refer to both types as a “taper lock” because they both use the tapered wedging action to lock to the shaft. The taper bushing, with it’s straight sides, uses a set screw to operate a vehicle the bushing in to the bore of the component being installed (sheave, sprocket, etc.). Be careful when setting up these screws. The holes with threads on the bushing are for removal just. Also be aware that the appearance of a flange on the outside of the bushing doesn’t necessarily mean it’s a QD design. Split Taper bushing also offers a flange, and the two are not interchangeable.
