Our direct supply chain to Martin Sprockets factories gets a wider range of QD Bushings delivered at the right time at the proper 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 from high quality engineered components with great tolerance. The feature can be easy to make use of and needs no extra alteration. These bushings can suit almost all types of assemblies and sizes. They will be the best choice in style for mechanical connections.
No costly re-boring: complete range of both metric and imperial available.
Standard range matches up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete short reach range obtainable, for compact light-weight assemblies & Clean, Compact Design.
Simple installation and removal.

The original sheave and pulley installation program 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 sure 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 first. Assemble key.
3. Placement QD bushing on shaft. Tighten arranged 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 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.
Notice: 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. Do not make use of 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 grip and press fit.
CAUTION: THIS GAP SHOULD NOT BE CLOSED.
Use a tapered or QD bushing from Ever-Power with qd bushing china sheaves, pulleys, sprockets and several other power transmission applications. Flanged quick-disconnect bushings include a completely split design to greatly help provide easy installation and disassembly. A tapered bushing with directly edges uses an interior screw to greatly help drive the bushing in to the shaft, while a split taper has a flange and a key on the bushing to help provide more drive.
QD bushings (in . and metric sizes) have a flanged style and feature a 4° taper with conventional or reverse installation. They are stocked in popular completed bore sizes and minimum plain bore for custom reboring.
Many people refer 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 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 style. Split Taper bushing also offers a flange, and both are not interchangeable. The QD design includes a split that continues through the flange. The Metal QD (Quick Disconnect) Type bushing offers flexible and easy set up while providing exceptional holding power. QD Bushings are utilized thought out the industry offering convenience and design flexibility. They are precision machined of quality Metal and are installed by tightening many cap screws. This draws the bushing into the taper bore of the merchandise 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 traditional or invert positions. This enables 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 constantly inserted from the exterior where they are often accessible. QD Bushings are available from share with all well-known bores within the range of each size bushing.
QD Bushings feature 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 required over standard bored-to-size bushings. Quick-Disconnect Bushings are essential for installation v-belt drives, synchronous belt drives and roller chain drives.
