Our immediate supply chain to Martin Sprockets factories gets a wider selection 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 constructed with high quality engineered 
materials with great tolerance. The feature is usually 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: complete range of both metric and imperial available.
Standard range suits up to 125mm/5″ shafts & Hub diameter required depends on the application.
Complete short reach range available, for compact light-weight assemblies & Clean, Compact Design.
Simple installation and removal.

Ease of installation and removal.
The initial sheave and pulley installation system 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 sure the tapered cone areas 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 first. Assemble key.
3. Placement QD bushing on shaft. Tighten established screw over key “hand 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.
Take 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 desk on back. Usually do not use 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 satisfactory cone grasp and press fit.
CAUTION: THIS GAP SHOULD 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 design to help provide easy installation and disassembly. A tapered bushing with straight edges uses an interior screw to greatly 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) have a flanged design and show a 4° taper with standard or reverse mounting. They are stocked in popular completed bore sizes and minimal plain bore for custom 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 into the bore of the component getting installed (sheave, sprocket, etc.). Be cautious when installing these screws. The holes with threads on the bushing are for removal only. Also be aware that the looks of a flange on the outside of the bushing doesn’t indicate it’s a QD style. Split Taper bushing also offers a flange, and both aren’t interchangeable. The QD design has a split that continues through the flange. The Metal QD (Quick Disconnect) Type bushing offers versatile and easy set up while providing exceptional holding power. QD Bushings are used considered the industry offering comfort and design flexibility. They are precision machined of quality Metal and are set up by tightening several 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 mounting of product in the conventional or reverse positions. This allows cap screws to end up being installed through product hub or bushing flange whichever is usually most convenient. A substantial benefit in installation, cap screws are constantly inserted from the outside 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 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 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.
