Our direct supply chain to Martin Sprockets factories gets a wider selection of QD Bushings delivered at the proper time at the right price.
Taper bushing are widely used as well as sprockets, v-belt pulleys, timing pulleys, coupling and other mechanical parts with taper bore connections.
Taper bushing series are made of high quality engineered materials with great tolerance. The feature is certainly 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 style for mechanical connections.
No costly re-boring: complete selection of both metric and imperial offered.
Standard range matches up to 125mm/5″ shafts & Hub diameter required depends on the application.
Complete brief reach range available, for compact lightweight assemblies & Clean, Compact Design.
Ease of installation and removal.

The initial sheave and pulley mounting system developed to facilitate installation and alternative of components.
The QD (Quick Detachable) design offers both conventional (flange outboard) and reverse (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 first. Assemble key.
3. Position QD bushing on shaft. Tighten established screw over key “hand tight” with standard 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 qd bushing china washers.
Take note: Install M thru S bushings in the hub to ensure that the two 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 desk on back. Usually do not use extensions on wrench handles. There must be a gap between your encounter 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.
Use a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and several other power tranny applications. Flanged quick-disconnect bushings include a completely split style to greatly help provide easy set up and disassembly. A tapered bushing with directly edges uses an interior screw to greatly help drive the bushing into the shaft, while a split taper has a flange and an integral on the bushing to greatly help provide more drive.
QD bushings (” and metric sizes) have a flanged style and feature a 4° taper with typical or reverse mounting. They are stocked in well-known completed bore sizes and minimum plain bore for custom reboring.
Many people refer 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 in to the bore of the component getting installed (sheave, sprocket, etc.). Be cautious when setting up these screws. The holes with threads on the bushing are for removal just. Also remember that the appearance of a flange externally of the bushing doesn't indicate it's a QD design. Split Taper bushing also has a flange, and both aren't interchangeable. The QD style has a split that proceeds through the flange. The Metal QD (Quick Disconnect) Type bushing offers versatile and easy set up while providing exceptional keeping power. QD Bushings are utilized thought out the industry offering comfort and design versatility. They are precision machined of quality Steel and are installed by tightening many cap screws. This draws the bushing into the taper bore of the product which compresses the bore of the bushing. QD bushings are often removed by using the cap screws as jack-screws. Dual drilled holes are furnished in QD Bushings permitting mounting of product in the traditional or invert positions. This enables cap screws to become installed through item hub or bushing flange whichever is certainly most convenient. A substantial benefit in installation, cap screws are at all times inserted from the outside where they are easily accessible. QD Bushings are available from stock with all well-known bores within the number of each size bushing.
QD Bushings feature 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 essential for mounting v-belt drives, synchronous belt drives and roller chain drives.
