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 reverse (flange inboard) mounting configurations.
1. Be sure the tapered cone surfaces 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 initial. Assemble key.
3. Position QD bushing on shaft. Tighten arranged screw over key “hands tight” with regular Allen wrench only. 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 washers.
NOTE: Install M thru S bushings in the hub to ensure that both 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. Usually do not use 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 grip and press fit.
CAUTION: THIS GAP MUST 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 design to greatly help provide easy installation and disassembly. A tapered bushing with directly edges uses an internal screw to greatly 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 (in . and metric sizes) possess a flanged design and show a 4° taper with regular or reverse installation. They are stocked in well-known finished bore sizes and minimum plain bore for customized 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 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 offers a flange, and the two are not interchangeable. The QD style includes a split that continues through the flange. The Steel QD (Quick Disconnect) Type bushing offers flexible and easy set up while providing exceptional keeping power. QD Bushings are used considered the industry offering convenience and design flexibility. They are precision machined of quality Metal and are installed by tightening a number of cap screws. This draws the bushing in to the taper bore of the product 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 reverse positions. This allows cap screws to become installed through item hub or bushing flange whichever is most convenient. A substantial benefit in set up, cap screws are often inserted from the outside where they are easily accessible. QD Bushings can be found from stock with all well-known 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 power is necessary over standard bored-to-size bushings. Quick-Disconnect Bushings are crucial for installation v-belt drives, synchronous belt drives and roller chain drives.

Our immediate supply chain to Martin Sprockets factories gets a wider selection of QD Bushings delivered at the proper time at the proper price.
Taper bushing are trusted 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 components with great tolerance. The feature can be easy to use and needs no additional alteration. These bushings can fit 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 obtainable.
Standard range matches up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete brief reach range obtainable, for compact light-weight assemblies & Clean, Compact Style.
Simple installation and removal.
The original 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) installation configurations.
1. Be certain the tapered cone surfaces of the bushing and the inside of the driven product are clean and free from anti-seize lubricants.
2. Slide QD bushing on shaft, flange end 1st. 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 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.
NOTE: Install M thru S bushings in the hub to ensure that both extra holes in the hub can be found as far as possible 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 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 reasonable cone grasp 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 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 has a flange and an integral on the bushing to greatly help provide more drive.
QD bushings (in . and metric sizes) have a flanged design and show a 4° taper with typical or reverse installation. They are stocked in well-known completed 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, runs on the set screw to drive the bushing into 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 just. 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 offers a flange, and both aren’t interchangeable. The QD style includes a split that continues through the flange. The Steel QD (Quick Disconnect) Type bushing offers versatile and easy set up while providing exceptional holding power. QD Bushings are used thought out the industry offering convenience and design flexibility. 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 merchandise which compresses the bore of the bushing. QD bushings are often removed utilizing the cap screws as jack-screws. Double drilled holes are furnished in QD Bushings permitting mounting of product in the conventional or reverse positions. This enables cap screws to end up being installed through item hub or bushing flange whichever is definitely most convenient. A significant benefit in installation, cap screws are often inserted from the outside where they are easily accessible. QD Bushings are available from share with all popular bores within the range of each size bushing.
