Our direct 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 made from high quality engineered materials with great tolerance. The feature is certainly easy to make use of and needs no additional alteration. These bushings can match almost all sorts 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 matches up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete brief reach range available, for compact lightweight assemblies & Clean, Compact Design.
Ease of installation and removal.

The original sheave and pulley mounting system developed to facilitate installation and alternative of components.
The QD (Quick Detachable) design provides for both conventional (flange outboard) and reverse (flange inboard) mounting configurations.
1. Be certain the tapered cone surfaces of the bushing and the inside of the driven product are clean and free from 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 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.
Notice: 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 saw cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque desk on back. 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 satisfactory cone hold and press fit.
CAUTION: THIS GAP SHOULD NOT BE CLOSED.
Make use of a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and several other power transmission applications. Flanged quick-disconnect bushings feature a completely split style to greatly help provide easy installation and disassembly. A tapered bushing with directly edges uses an internal screw to greatly help drive the bushing in to the shaft, while a split taper has a flange and an integral on the bushing to greatly help provide more drive.
QD bushings (in . and metric sizes) possess a flanged design and feature a 4° taper with standard or reverse installation. They are stocked in popular 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 into the bore of the component getting installed (sheave, sprocket, etc.). Be careful when setting up these screws. The holes with threads on the bushing are for removal only. Also be aware that the looks of a flange externally of the bushing doesn’t necessarily mean it’s a QD design. Split Taper bushing also has a flange, and the two aren’t interchangeable. The QD style has a split that proceeds through the flange. The Steel QD (Quick Disconnect) Type bushing offers versatile and easy installation while providing exceptional holding power. QD Bushings are utilized thought out 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 often removed utilizing the cap screws as jack-screws. Double drilled holes are furnished in QD Bushings permitting mounting of product in the traditional or reverse positions. This enables cap screws to be installed through product hub or bushing flange whichever is usually most convenient. A substantial benefit in set up, cap screws are often inserted from the outside where they are easily accessible. QD Bushings are available from stock with all well-known bores within the number 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 mounting v-belt drives, synchronous belt drives and roller chain drives.
