Our direct supply chain to Martin Sprockets factories gets a wider selection of QD Bushings delivered at the proper time at the proper price.
Taper bushing are trusted 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 materials with great tolerance. The feature is certainly easy to make use of and needs no extra alteration. These bushings can suit 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 obtainable.
Standard range suits up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete brief reach range obtainable, for compact lightweight 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 alternative 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 within of the driven product are clean and free from anti-seize lubricants.
2. Slide QD bushing on shaft, flange end 1st. Assemble key.
3. Position QD bushing on shaft. Tighten established screw over key “hands tight” with regular Allen wrench only. Usually do not use excessive force.
4. Slide large 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 the two extra holes in the hub can be found as far as possible 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 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 Ever-Power with sheaves, pulleys, sprockets and many other power transmission applications. Flanged quick-disconnect bushings 
feature a completely split design to greatly help provide easy set up 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 has a flange and an integral on the bushing to help provide more drive.
QD bushings (” and metric sizes) have a flanged design and show a 4° taper with standard or reverse installation. They are stocked in well-known completed 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, runs on the set screw to drive the bushing in to the bore of the component becoming set up (sheave, sprocket, etc.). Be cautious when setting up these screws. The holes with threads on the bushing are for removal just. Also be aware that the looks 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 the two 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 utilized thought out the industry offering comfort and design versatility. 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 product 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 mounting of product in the conventional or reverse positions. This enables cap screws to become installed through product hub or bushing flange whichever is definitely most convenient. A substantial benefit in set up, cap screws are at all times inserted from the outside where they are easily accessible. QD Bushings can be found from share 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 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.
