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 together with sprockets, v-belt pulleys, timing pulleys, coupling and other mechanical parts with taper bore connections.
Taper bushing series are constructed with high quality engineered components with great tolerance. The feature is 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 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 on the application.
Complete brief reach range offered, for compact light-weight assemblies & Clean, Compact Design.
Simple installation and removal.

The original 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 invert (flange inboard) mounting 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. qd bushing china Placement QD bushing on shaft. Tighten established screw over key “hands tight” with standard 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.
Take note: Install M thru S bushings in the hub so 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 table on back. Usually 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 MUST NOT BE CLOSED.
Use a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and several other power transmitting applications. Flanged quick-disconnect bushings include a completely split style to greatly help provide easy set up and disassembly. A tapered bushing with directly edges uses an interior screw to help drive the bushing in to the shaft, while a split taper includes a flange and an integral on the bushing to greatly help provide more drive.
QD bushings (” and metric sizes) possess a flanged design and show a 4° taper with conventional or reverse mounting. They are stocked in well-known completed bore sizes and minimum plain bore for customized reboring.
Many people make reference 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 set up (sheave, sprocket, etc.). Be careful when installing these screws. The holes with threads on the bushing are for removal only. Also be aware that the appearance of a flange externally of the bushing doesn’t necessarily mean it’s a QD design. Split Taper bushing also has a flange, and both aren’t interchangeable. The QD design includes a split that proceeds 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 comfort and design versatility. They are precision machined of quality Steel and are installed 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 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 enables cap screws to be installed through product hub or bushing flange whichever is most convenient. A significant benefit in installation, cap screws are generally inserted from the exterior where they are often accessible. QD Bushings are available from share with all well-known bores within the number of each 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 pressure 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.
