Our direct 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 widely used as well as sprockets, v-belt pulleys, timing pulleys, coupling and other mechanical parts with taper bore connections.
Taper bushing series are constructed with high quality engineered materials with great tolerance. The feature is easy to use and needs no additional alteration. These bushings can match almost all sorts of assemblies and sizes. They are the best choice in design for mechanical connections.
No costly re-boring: full range of both metric and imperial offered.
Standard range fits up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete brief reach range available, for compact lightweight assemblies & Clean, Compact Style.
Simple installation and removal.

The original sheave and pulley mounting system developed to facilitate installation and replacement 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 item 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 standard Allen wrench only. Usually 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.
NOTE: Install M thru S bushings in the hub so that the two extra holes in the hub are located as far as possible from the bushing’s noticed cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque table 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 satisfactory 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 many other power transmitting applications. Flanged quick-disconnect bushings include a completely split style to help provide easy set up 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 has a flange and a key on the bushing to help provide more drive.
QD bushings (in . and metric sizes) have a flanged design and feature a 4° taper with typical or reverse mounting. They are stocked in popular finished bore sizes and minimum plain bore for custom reboring.
Many 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, uses a set screw to operate a vehicle the bushing in to the bore of the component becoming installed (sheave, sprocket, etc.). Be cautious when setting up these screws. The holes with threads on the bushing are for removal only. Also remember 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 both aren’t interchangeable. The QD style has a split that continues through the flange. The Steel QD (Quick Disconnect) Type bushing offers flexible and easy installation while providing exceptional keeping power. QD Bushings are utilized thought out the industry offering convenience and design versatility. 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 product which compresses the bore of the bushing. QD bushings are easily removed by using 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 certainly most convenient. A significant benefit in set up, cap screws are at all times inserted from the outside where they are easily accessible. QD Bushings can be found from share with all well-known 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 applied to sprockets, sheaves, and pulleys where more clamping push 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.
