Our immediate supply chain to Martin Sprockets factories gets a wider range of QD Bushings delivered at the right time at the proper price.
Taper bushing are trusted together with 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 usually easy to make use of and needs no additional alteration. These bushings can fit almost all kinds 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 obtainable.
Standard range fits up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete short reach range obtainable, for compact light-weight assemblies & Clean, Compact Style.
Simple installation and removal.

Ease of installation and removal.
The original sheave and pulley installation program developed to facilitate installation and substitute of components.
The QD (Quick Detachable) design provides for both conventional (flange outboard) and invert (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 of 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. 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 so 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. Do not make use of extensions on wrench handles. There should be a gap between the face of the sheave or sprocket hub and the flange of the QD bushing to insure a reasonable cone grasp and press fit.
CAUTION: THIS GAP MUST NOT BE CLOSED.
Make use of a tapered or QD bushing from qd bushing china Ever-Power with sheaves, pulleys, sprockets and many other power transmitting applications. Flanged quick-disconnect bushings feature a completely split style to help provide easy installation and disassembly. A tapered bushing with straight edges uses an internal screw to help drive the bushing in to the shaft, while a split taper includes a flange and a key on the bushing to help provide more drive.
QD bushings (in . and metric sizes) possess a flanged design and show a 4° taper with standard or reverse installation. They are stocked in popular finished bore sizes and minimal 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, uses a set screw to drive the bushing into the bore of the component being set up (sheave, sprocket, etc.). Be careful when installing these screws. The holes with threads on the bushing are for removal only. Also remember that the looks of a flange on the outside of the bushing doesn’t necessarily mean it’s a QD style. Split Taper bushing also offers a flange, and the two are not interchangeable. The QD design includes a split that continues through the flange. The Steel QD (Quick Disconnect) Type bushing offers flexible and easy installation while providing exceptional holding power. QD Bushings are used considered the industry offering convenience and design flexibility. They are precision machined of quality Metal and are set up 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 allows cap screws to be installed through product hub or bushing flange whichever is usually most convenient. A significant benefit in set up, cap screws are constantly inserted from the exterior where they are often accessible. QD Bushings can be found from share with all popular 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 applied to sprockets, sheaves, and pulleys where more clamping pressure is necessary over standard bored-to-size bushings. Quick-Disconnect Bushings are crucial for installation v-belt drives, synchronous belt drives and roller chain drives.
