The original sheave and pulley installation system developed to facilitate installation and alternative of components.
The QD (Quick Detachable) design provides for 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 item are clean and free from anti-seize lubricants.
2. Slide QD bushing on shaft, flange end initial. Assemble key.
3. Position QD bushing on shaft. Tighten arranged screw over key “hands tight” with standard Allen wrench only. Do not use excessive force.
4. Slide large 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 qd bushing china bushings in the hub to ensure that both extra holes in the hub are located 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 make use of extensions on wrench handles. There should be a gap between your encounter 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.
Make use of 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 set up and disassembly. A tapered bushing with straight edges uses an interior screw to help drive the bushing in to 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 popular finished bore sizes and minimum plain bore for customized 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, uses a set screw to drive the bushing in to the bore of the component getting 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 on the outside 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 design includes a split that proceeds through the flange. The Steel QD (Quick Disconnect) Type bushing offers versatile and easy set up while providing exceptional holding power. QD Bushings are utilized considered the industry offering comfort and design flexibility. They are precision machined of quality Metal and are installed 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 enables cap screws to end up being installed through item hub or bushing flange whichever is usually most convenient. A significant benefit in set up, cap screws are usually inserted from the exterior where they are easily accessible. QD Bushings can be found from share with all popular 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 force is necessary over standard bored-to-size bushings. Quick-Disconnect Bushings are essential for mounting v-belt drives, synchronous belt drives and roller chain drives.

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 together with 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 can be easy to use and needs no additional alteration. These bushings can suit almost all types of assemblies and sizes. They are the best choice in style for mechanical connections.
No costly re-boring: complete range of both metric and imperial offered.
Standard range fits up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete short reach range obtainable, for compact lightweight assemblies & Clean, Compact Design.
Ease of installation and removal.
The original sheave and pulley mounting program developed to facilitate installation and replacement of components.
The QD (Quick Detachable) design offers both conventional (flange outboard) and invert (flange inboard) installation configurations.
1. Be sure the tapered cone surfaces 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. Position QD bushing on shaft. Tighten set screw over key “hands tight” with regular Allen wrench only. 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.
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 feasible from the bushing’s noticed cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque desk on back. Do not use extensions on wrench handles. There should be a gap between your face of the sheave or sprocket hub and the flange of the QD bushing to insure a satisfactory cone hold and press fit.

Flanged quick-disconnect bushings feature a completely split design to greatly help provide easy installation and disassembly. A tapered bushing with straight edges uses an interior screw to help drive the bushing into 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) have a flanged design and show a 4° taper with conventional or reverse mounting. They are stocked in well-known finished bore sizes and minimal 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, uses a set screw to operate a vehicle the bushing into the bore of the component getting set up (sheave, sprocket, etc.). Be careful when setting up these screws. The holes with threads on the bushing are for removal only. Also remember that the looks of a flange on the outside of the bushing doesn’t necessarily mean it’s a QD design. Split Taper bushing also has a flange, and both are not interchangeable.

This draws the bushing into the taper bore of the merchandise which compresses the bore of the bushing. QD bushings are often removed by using the cap screws as jack-screws. Double 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 definitely most convenient. A significant benefit in installation, cap screws are generally inserted from the exterior where they are easily accessible. QD Bushings can be found from share with all popular bores within the range of every size bushing.
