The initial sheave and pulley installation system developed to facilitate installation and replacement 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 surfaces of the bushing and the inside of the driven item are clean and free of anti-seize lubricants.
2. Slide QD bushing on shaft, flange end initial. Assemble key.
3. Placement QD bushing on shaft. Tighten set 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 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 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 table 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 satisfactory cone grasp and press fit.
CAUTION: THIS GAP MUST 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 set up and disassembly. A tapered bushing with directly edges uses an internal screw to 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 (inch and metric sizes) have a flanged design and feature a 4° taper with conventional or reverse mounting. 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, uses a set screw to drive the bushing in to the bore of the component being set up (sheave, sprocket, etc.). Be cautious when installing these screws. The holes with threads on the bushing are for removal only. Also remember that the appearance 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 the two are not interchangeable. The QD style includes 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 flexibility. They are precision machined of quality Steel 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 often removed utilizing the cap screws as jack-screws. Dual drilled holes are furnished in QD Bushings permitting installation of product in the conventional or reverse positions. This allows cap screws to end up being installed through item hub or bushing flange whichever is most convenient. A significant benefit in installation, cap screws are often inserted from the exterior where they are often accessible. QD Bushings can be found from stock with all popular bores within the range of every size bushing.
QD Bushings include a split tapered flange with the split central to the flange and taper. They are applied to sprockets, sheaves, and pulleys where more clamping push 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 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 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 is usually easy to use and needs no extra alteration. These bushings can suit almost all sorts of assemblies and sizes. They are the best choice in style for mechanical connections.
No costly re-boring: full selection of both metric and imperial available.
Standard range suits up to 125mm/5″ shafts & Hub diameter required depends on the application.
Complete short reach range available, for compact lightweight assemblies & Clean, Compact Style.
Simple installation and removal.
The initial 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 surfaces 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 “hand tight” with standard 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.
Take note: Install M thru S bushings in the hub to ensure that the two extra holes in the hub are located 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 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 grasp 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 transmitting applications. Flanged quick-disconnect bushings include a completely split style to help provide easy installation and disassembly. A tapered bushing with directly edges uses an interior screw to help drive the bushing into the shaft, while a split taper has a flange and a key on the bushing to greatly help provide more drive.
QD bushings (inch and metric sizes) have a flanged design and feature a 4° taper with typical or reverse installation. They are stocked in popular 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 drive the bushing into the bore of the component being installed (sheave, sprocket, etc.). Be careful when setting up these screws. The holes with threads on the bushing are for removal just. Also remember that the looks of a flange externally of the bushing doesn’t indicate it’s a QD style. Split Taper bushing also has a flange, and the two are not interchangeable. The QD design includes a split that proceeds through the flange. The Steel QD (Quick Disconnect) Type bushing offers flexible and easy installation while providing exceptional holding power. QD Bushings are used 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 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 conventional or invert positions. This enables cap screws to become installed through item hub or bushing flange whichever is usually most convenient. A significant benefit in installation, cap screws are always inserted from the exterior where they are easily accessible. QD Bushings are available from share with all popular bores within the number of each size bushing.
