Our immediate 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 constructed with high quality engineered materials with great tolerance. The feature can be easy to make use of and needs no additional alteration. These bushings can fit almost all sorts of assemblies and sizes. They will be the best choice in design for mechanical connections.
No costly re-boring: complete range of both metric and imperial obtainable.
Standard range matches up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete short reach range offered, for compact light-weight assemblies & Clean, Compact Design.
Ease of installation and removal.

The original sheave and pulley installation system developed to facilitate installation and substitute of components.
The QD (Quick Detachable) design offers both conventional (flange outboard) and reverse (flange inboard) mounting configurations.
1. Be certain the tapered cone surfaces of the bushing and the within of the driven product are clean and free of anti-seize lubricants.
2. Slide QD bushing on shaft, flange end 1st. Assemble key.
3. Placement QD bushing on shaft. Tighten established screw over key “hands tight” with regular Allen wrench only. 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.
Notice: Install M thru S bushings in the hub to ensure that both extra holes in the hub can be found as far as feasible from the bushing’s saw cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque table on back. Usually do not use 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 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 many 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 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 help provide more drive.
QD bushings (in . and metric sizes) possess a flanged design and feature a 4° taper with typical or reverse mounting. They are stocked in well-known finished 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, runs on the set screw to drive the bushing in to 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 be aware that the looks of a flange externally of the bushing doesn’t necessarily mean it’s a QD style. Split Taper bushing also has a flange, and both aren’t interchangeable. The QD style has a split that proceeds through the flange. The Steel QD (Quick Disconnect) Type bushing offers flexible and easy set up while providing exceptional holding power. QD Bushings are utilized considered the industry offering comfort and design versatility. They are precision machined of quality Metal and are set up by tightening many 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 installation of product in the traditional or invert 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 set up, cap screws are always inserted from the exterior where they are often 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 used on sprockets, sheaves, and pulleys where more clamping pressure 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.
