The initial sheave and pulley mounting program developed to facilitate installation and replacement of components.
The QD (Quick Detachable) design offers both conventional (flange outboard) and invert (flange inboard) installation configurations.
1. Be certain the tapered cone surfaces 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 set screw over key “hand tight” with standard 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.
NOTE: Install M thru S bushings in the hub so that both 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. Usually do not use 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.
CAUTION: THIS GAP SHOULD 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 include a completely split design to greatly help provide easy installation and disassembly. A tapered bushing with directly edges uses an interior screw to greatly help drive the bushing in to the shaft, while a split taper has a flange and an integral on the bushing to help provide more drive.
QD bushings (inch and metric sizes) possess a flanged style and feature a 4° taper with typical or reverse installation. They are stocked in popular finished bore sizes and minimal plain bore for customized reboring.
Many people make reference 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, runs on the set screw to drive the bushing in to the bore of the component getting installed (sheave, sprocket, etc.). Be cautious when setting up 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 aren’t interchangeable. The QD style has a split that continues through the flange. The Metal QD (Quick Disconnect) Type bushing offers versatile and easy set up while providing exceptional holding power. QD Bushings are used considered the industry offering comfort and design versatility. They are precision machined of quality Steel and are set up by tightening many cap screws. This draws the bushing into 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. Dual drilled holes are furnished in QD Bushings permitting mounting of product in the conventional or reverse positions. This allows cap screws to end up being 
installed through item hub or bushing flange whichever is certainly most convenient. A significant benefit in set up, cap screws are generally inserted from the outside where they are easily accessible. QD Bushings are available from stock with all popular bores within the number of every 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 force is required over standard bored-to-size bushings. Quick-Disconnect Bushings are crucial 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 proper time at the proper price.
Taper bushing are trusted as well as sprockets, v-belt pulleys, timing pulleys, coupling and other mechanical parts with taper bore connections.
Taper bushing series are made of high quality engineered materials with great tolerance. The feature is definitely easy to use and needs no extra alteration. These bushings can fit almost all sorts of assemblies and sizes. They are the best choice in style for mechanical connections.
No costly re-boring: full range of both metric and imperial obtainable.
Standard range suits up to 125mm/5″ shafts & Hub diameter required depends on the application.
Complete short reach range offered, for compact lightweight assemblies & Clean, Compact Style.
Simple installation and removal.

The QD (Quick Detachable) design provides for both conventional (flange outboard) and invert (flange inboard) installation configurations.
1. Be sure the tapered cone areas of the bushing and the within of the driven item are clean and free from 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 standard 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 so that the two extra holes in the hub can be found as far as possible from the bushing’s noticed cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque desk on back. Usually do not make use of 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 grasp and press fit.
