Our immediate supply chain to Martin Sprockets factories gets a wider range of QD Bushings delivered at the proper time at the proper price.
Taper qd bushing china 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 constructed with high quality engineered materials with great tolerance. The feature is 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 design for mechanical connections.
No costly re-boring: full range of both metric and imperial obtainable.
Standard range fits up to 125mm/5″ shafts & Hub diameter required depends on the application.
Complete brief reach range available, for compact light-weight assemblies & Clean, Compact Design.
Simple installation and removal.

Complete short reach range available, for compact light-weight assemblies & Clean, Compact Design.
Ease of installation and removal.
The initial sheave and pulley mounting system developed to facilitate installation and substitute of components.
The QD (Quick Detachable) design offers both conventional (flange outboard) and invert (flange inboard) installation configurations.
1. Be certain the tapered cone areas of the bushing and the inside of the driven product are clean and free of anti-seize lubricants.
2. Slide QD bushing on shaft, flange end first. Assemble key.
3. Position QD bushing on shaft. Tighten set screw over key “hands tight” with regular Allen wrench only. Usually 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 both extra holes in the hub can be found as far as feasible from the bushing’s noticed cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque desk on back. Usually 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 sheaves, pulleys, sprockets and many other power transmitting applications. Flanged quick-disconnect bushings feature a completely split style to help provide easy set up and disassembly. A tapered bushing with straight edges uses an interior screw to greatly 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 (” and metric sizes) have a flanged design and feature a 4° taper with conventional or reverse installation. They are stocked in well-known finished bore sizes and minimum 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, uses a set screw to drive the bushing in to the bore of the component being installed (sheave, sprocket, etc.). Be careful when installing these screws. The holes with threads on the bushing are for removal just. Also be aware that the appearance 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 are not interchangeable. The QD design includes a split that proceeds 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 considered the industry offering convenience and design versatility. They are precision machined of quality Metal and are installed 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 easily removed utilizing the cap screws as jack-screws. Double drilled holes are furnished in QD Bushings permitting installation of product in the traditional or reverse positions. This allows cap screws to become installed through product hub or bushing flange whichever is definitely most convenient. A significant benefit in installation, cap screws are generally inserted from the outside where they are often accessible. QD Bushings are available from share with all popular 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 pressure is required over standard bored-to-size bushings. Quick-Disconnect Bushings are crucial for installation v-belt drives, synchronous belt drives and roller chain drives.
