Our immediate 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 as well as 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 definitely easy to use and needs no additional alteration. These bushings can fit almost all kinds 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 available.
Standard range fits up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete brief reach range available, for compact light-weight assemblies & Clean, Compact Style.
Ease of installation and removal.

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 areas of the bushing and the inside of the driven product 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 established 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 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 both extra holes in the hub can be found as far as feasible from the bushing’s noticed 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 the encounter 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 SHOULD NOT BE CLOSED.
Make use of a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and several other power transmission applications. Flanged quick-disconnect bushings include a completely split style to greatly help provide easy set up and disassembly. A tapered bushing with straight edges uses an internal 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.
QD bushings (” and metric sizes) have a flanged style and show a 4° taper with regular or reverse installation. They are stocked in well-known finished bore sizes and minimum plain bore for custom 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 operate a vehicle the bushing in to the bore of the component being installed (sheave, sprocket, etc.). Be careful when setting up these screws. The holes with threads on the bushing are for removal just. Also be aware that the appearance of a flange on the outside of the bushing doesn’t necessarily mean it’s a QD design. Split Taper bushing also offers a flange, and both are not interchangeable. The QD style has a split that continues through the flange. The Steel QD (Quick Disconnect) Type bushing offers versatile and easy set up while providing exceptional keeping 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 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. Double drilled holes are furnished in QD Bushings permitting installation of product in the conventional or reverse positions. This enables cap screws to be installed through product hub or bushing flange whichever is most convenient. A significant benefit in set up, cap screws are often inserted from the outside where they are often accessible. QD Bushings can be found from stock with all well-known bores within the range 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 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.
