The initial sheave and pulley mounting program developed to facilitate installation and substitute of components.
The QD (Quick Detachable) design provides for both conventional (flange outboard) and reverse (flange inboard) installation configurations.
1. Be sure the tapered cone areas of the qd bushing china bushing and the within of the driven product are clean and free of anti-seize lubricants.
2. Slide QD bushing on shaft, flange end 1st. Assemble key.
3. Placement QD bushing on shaft. Tighten arranged screw over key “hands tight” with regular Allen wrench only. Usually do not use excessive force.
4. Slide large 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 the two extra holes in the hub are located as far as feasible from the bushing’s saw cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque desk on back. 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 MUST NOT BE CLOSED.
Make use of a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and several other power tranny applications. Flanged quick-disconnect bushings feature a completely split design to help provide easy set up and disassembly. A tapered bushing with directly edges uses an interior 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.
QD bushings (” and metric sizes) possess a flanged design and show a 4° taper with typical or reverse installation. They are stocked in popular finished 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 set up (sheave, sprocket, etc.). Be careful when installing these screws. The holes with threads on the bushing are for removal only. Also be aware that the appearance of a flange on the outside of the bushing doesn’t indicate it’s a QD design. Split Taper bushing also has a flange, and both aren’t interchangeable. The QD style includes a split that continues through the flange. The Metal QD (Quick Disconnect) Type bushing offers flexible and easy set up while providing exceptional holding power. QD Bushings are used thought out the industry offering comfort and design flexibility. They are precision machined of quality Metal and are installed by tightening a number of cap screws. This draws the bushing in to the taper bore of the merchandise which compresses the bore of the bushing. QD bushings are often removed by using the cap screws as jack-screws. Double drilled holes are furnished in QD Bushings permitting installation of product in the traditional or invert positions. This allows cap screws to be installed through item hub or bushing flange whichever can be most convenient. A significant benefit in set up, cap screws are at all times inserted from the outside where they are often accessible. QD Bushings are available from stock with all popular bores within the range of each size bushing.
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 pressure 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 selection of QD Bushings delivered at the proper time at the proper price.
Taper bushing are widely used 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 components with great tolerance. The feature is certainly easy to use and needs no extra alteration. These bushings can suit almost all types of assemblies and sizes. They are the best choice in style for mechanical connections.
No costly re-boring: complete range of both metric and imperial obtainable.
Standard range fits up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete brief reach range offered, for compact light-weight assemblies & Clean, Compact Style.
Ease of installation and removal.
The original sheave and pulley mounting system developed to facilitate installation and alternative of components.
The QD (Quick Detachable) design provides for both conventional (flange outboard) and invert (flange inboard) installation configurations.
1. Be certain the tapered cone areas of the bushing and the inside of the driven item 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 arranged screw over key “hands tight” with regular Allen wrench only. Usually 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.
Take note: Install M thru S bushings in the hub to ensure that the two extra holes in the hub are located as far as feasible from the bushing’s saw cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque table on back. Usually do not use extensions on wrench handles. There must be a gap between the face of the sheave or sprocket hub and the flange of the QD bushing to insure a reasonable cone grasp and press fit.

Make use of a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and several other power transmitting applications. Flanged quick-disconnect bushings feature a completely split style to help provide easy installation and disassembly. A tapered bushing with straight edges uses an internal screw to greatly help drive the bushing in to the shaft, while a split taper has a flange and a key on the bushing to help provide more drive.
QD bushings (in . and metric sizes) possess a flanged design and feature a 4° taper with regular or reverse mounting. They are stocked in well-known finished bore sizes and minimum plain bore for customized reboring.
