Our immediate supply chain to Martin Sprockets factories gets a wider range of QD Bushings delivered at the right time at the right 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 components with great tolerance. The feature is easy to use and needs no extra alteration. These bushings can match almost all sorts of assemblies and sizes. They will be the best choice in design for mechanical connections.
No costly re-boring: full selection of both metric and imperial obtainable.
Standard range fits up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete short reach range available, for compact light-weight assemblies & Clean, Compact Style.
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 offers both conventional (flange outboard) and invert (flange inboard) mounting configurations.
1. Be certain the tapered cone areas of the bushing and the inside of the driven item 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 set screw over key “hand tight” with standard 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 to ensure that both extra holes in the hub can be found as far as possible from the bushing’s saw cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque table 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 grip 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 tranny applications. Flanged quick-disconnect bushings include a completely split design to 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 help provide more drive.
QD bushings (” and metric sizes) have a flanged style and feature a 4° taper with conventional or reverse mounting. They are stocked in popular 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 operate a vehicle the bushing into 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 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 offers a flange, and both aren’t interchangeable. The QD style includes a split that proceeds through the flange. The Metal QD (Quick Disconnect) Type bushing offers versatile and easy installation while providing exceptional holding power. QD Bushings are used considered the industry offering convenience and design flexibility. They are precision machined of quality Steel and are set up by tightening a number of cap screws. This draws the bushing into 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. Dual drilled holes are furnished in QD Bushings permitting mounting of product in the conventional or invert positions. This allows cap screws to become installed through item hub or bushing flange whichever can be most convenient. A significant benefit in set up, cap screws are always inserted from the outside where they are often accessible. QD Bushings can be found 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 drive is required over standard bored-to-size bushings. Quick-Disconnect Bushings are crucial for mounting v-belt drives, synchronous belt drives and roller chain drives.
