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 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 can be easy to make use of and needs no extra alteration. These bushings can fit almost all sorts of assemblies and sizes. They will be the best choice in style for mechanical connections.
No costly re-boring: full selection of both metric and imperial obtainable.
Standard range matches up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete brief reach range obtainable, for compact lightweight assemblies & Clean, Compact Style.
Ease of installation and removal.

The original sheave and pulley mounting program 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 certain the tapered cone surfaces of the bushing and the inside 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 set 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 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 both extra holes in the hub are located as far as feasible 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 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 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 feature a completely split style to greatly help provide easy set up and disassembly. A tapered bushing with directly edges uses an internal screw to help drive the bushing into the shaft, while a split taper includes 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 typical or reverse installation. They are stocked in well-known finished bore sizes and minimum 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 being set up (sheave, sprocket, etc.). Be careful when setting up these screws. The holes with threads on the bushing are for removal just. Also remember that the looks of a flange externally of the bushing doesn’t necessarily mean it’s a QD design. 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 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 into the taper bore of the merchandise which compresses the bore of the bushing. QD bushings are often removed utilizing the cap screws as jack-screws. Dual drilled holes are furnished in QD Bushings permitting installation of product in the traditional or invert positions. This enables cap screws to be installed through item hub or bushing flange whichever can be most convenient. A substantial benefit in set up, cap screws are generally inserted from the exterior where they are easily accessible. QD Bushings can be found 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 power is necessary over standard bored-to-size bushings. Quick-Disconnect Bushings are essential for installation v-belt drives, synchronous belt drives and roller chain drives.
