Our immediate supply chain to Martin Sprockets factories gets a wider range 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 made of high quality engineered components with great tolerance. The feature is certainly easy to use and needs no additional alteration. These bushings can suit almost all sorts of assemblies and sizes. They will be the best choice in design for mechanical connections.
No costly re-boring: full selection of both metric and imperial available.
Standard range fits up to 125mm/5″ shafts & Hub diameter required depends on the application.
Complete short reach range offered, for compact lightweight assemblies & Clean, Compact Design.
Ease of installation and removal.

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) mounting configurations.
1. Be certain the tapered cone surfaces of the bushing and the within of the driven product are clean and free of anti-seize lubricants.
2. Slide QD bushing on shaft, flange end first. Assemble key.
3. Position QD bushing on shaft. Tighten set screw over key “hand tight” with regular Allen wrench only. Do not use excessive force.
4. Slide large 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 desk on back. Do not use extensions on wrench handles. There must 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.
CAUTION: THIS GAP MUST NOT BE CLOSED.
Make use of a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and many other power tranny applications. Flanged quick-disconnect bushings include a completely split design to help provide easy set up 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 includes a flange and an integral on the bushing to help provide more drive.
QD bushings (in . and metric sizes) have a flanged design and feature a 4° taper with regular or reverse installation. They are stocked in well-known completed bore sizes and minimum plain bore for custom reboring.
Many qd bushing china people refer 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 operate a vehicle the bushing into the bore of the component becoming set up (sheave, sprocket, etc.). Be cautious when installing these screws. The holes with threads on the bushing are for removal just. Also remember that the looks of a flange on the outside of the bushing doesn’t indicate it’s a QD style. Split Taper bushing also has a flange, and both are not interchangeable. The QD design has a split that proceeds through the flange. The Steel QD (Quick Disconnect) Type bushing offers versatile and easy set up while providing exceptional keeping power. QD Bushings are utilized considered the industry offering convenience and design versatility. They are precision machined of quality Steel and are installed by tightening several 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. Double drilled holes are furnished in QD Bushings permitting mounting of product in the traditional or invert positions. This allows cap screws to be installed through item hub or bushing flange whichever is most convenient. A significant benefit in installation, cap screws are usually inserted from the exterior where they are easily accessible. QD Bushings are available from stock with all popular bores within the number of every size bushing.
QD Bushings include a split tapered flange with the split central to the flange and taper. 
They are used on sprockets, sheaves, and pulleys where more clamping power is necessary over standard bored-to-size bushings. Quick-Disconnect Bushings are crucial for mounting v-belt drives, synchronous belt drives and roller chain drives.
