The initial sheave and pulley installation system developed to facilitate installation and alternative of components.
The QD (Quick Detachable) design offers both conventional (flange outboard) and reverse (flange inboard) mounting configurations.
1. Be certain the tapered cone surfaces of the bushing and the within of the driven product are clean and free from anti-seize lubricants.
2. Slide QD bushing on shaft, flange end first. Assemble key.
3. Placement QD bushing on shaft. Tighten established screw over key “hands tight” with qd bushing china 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 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. 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 satisfactory cone grasp and press fit.
CAUTION: THIS GAP MUST NOT BE CLOSED.
Use 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 style to greatly help provide easy set up and disassembly. A tapered bushing with straight edges uses an interior screw to greatly help drive the bushing into the shaft, while a split taper has 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 standard or reverse installation. They are stocked in popular finished bore sizes and minimum plain bore for customized reboring.
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, runs on the set screw to drive the bushing into the bore of the component being installed (sheave, sprocket, etc.). Be cautious when setting up these screws. The holes with threads on the bushing are for removal only. Also be aware that the looks of a flange on the outside of the bushing doesn’t indicate it’s a QD style. Split Taper bushing also offers a flange, and the two are not interchangeable. The QD style includes a split that proceeds through the flange. The Steel QD (Quick Disconnect) Type bushing offers flexible 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 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 easily 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 enables cap screws to end up being installed through item hub or bushing flange whichever is usually most convenient. A significant benefit in installation, cap screws are usually inserted from the outside where they are easily accessible. QD Bushings can be found from stock with all well-known bores within the range of every 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 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 direct supply chain to Martin Sprockets factories gets a wider selection of QD Bushings delivered at the proper time at the right 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 constructed with high quality engineered components with great tolerance. The feature is usually easy to make use of and needs no additional alteration. These bushings can suit almost all sorts of assemblies and sizes. They are the best choice in style for mechanical connections.
No costly re-boring: complete selection 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 Design.
Simple installation and removal.
The initial sheave and pulley installation system 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 surfaces of the bushing and the within of the driven product 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. 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 can be found 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. Do not make use of extensions on wrench handles. There should be a gap between your encounter of the sheave or sprocket hub and the flange of the QD bushing to insure a satisfactory cone hold and press fit.

Flanged quick-disconnect bushings feature a completely split style to help provide easy set up and disassembly. A tapered bushing with straight edges uses an interior screw to help drive the bushing into the shaft, while a split taper has a flange and an integral on the bushing to help provide more drive.

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 operate a vehicle the bushing in to the bore of the component getting set up (sheave, sprocket, etc.). Be cautious when installing these screws. The holes with threads on the bushing are for removal just. Also be aware that the appearance of a flange externally of the bushing doesn’t indicate it’s a QD style. Split Taper bushing also offers a flange, and both are not interchangeable. The QD style includes a split that proceeds through the flange. The Steel QD (Quick Disconnect) Type bushing offers flexible and easy set up while providing exceptional holding power.

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. Dual drilled holes are furnished in QD Bushings permitting mounting of product in the traditional or reverse positions. This allows cap screws to be installed through product hub or bushing flange whichever can be most convenient. A significant benefit in installation, cap screws are usually inserted from the outside where they are often accessible. QD Bushings can be found from stock with all popular 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 push is required over standard bored-to-size bushings.
