The initial sheave and pulley mounting system developed to facilitate installation and alternative of components.
The QD (Quick Detachable) design provides for both conventional (flange outboard) and invert (flange inboard) mounting configurations.
1. Be certain the tapered cone areas 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 first. 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.
Notice: Install M thru S bushings in the hub to ensure that both extra holes in the hub are located 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 face of the sheave or sprocket hub and the flange of the QD bushing to insure a reasonable cone hold and press fit.
CAUTION: THIS GAP MUST NOT BE CLOSED.
Use a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and several other power transmitting applications. Flanged quick-disconnect bushings include a completely split style to help provide easy set up and disassembly. A tapered bushing with directly edges uses an interior screw to greatly 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) possess a flanged style and feature a 4° taper with typical or reverse installation. They are stocked in well-known completed bore sizes and minimal 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 into the bore of the component being set up (sheave, sprocket, etc.). Be cautious when setting up these screws. The holes with threads on the bushing are for removal just. Also be aware that the appearance of a flange on the outside of the bushing doesn’t indicate 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 installation while providing exceptional holding power. QD Bushings are utilized considered the industry offering convenience and design versatility. They are precision machined of quality Steel and are set up by tightening several 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 utilizing the cap screws as jack-screws. Dual drilled holes are furnished in QD Bushings permitting installation of product in the traditional or reverse positions. This enables cap screws to end up being installed through product hub or bushing flange whichever is qd bushing china certainly most convenient. A significant benefit in set up, cap screws are generally inserted from the exterior where they are easily accessible. QD Bushings are available from share with all well-known bores within the range of each 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 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.
Our direct supply chain to Martin Sprockets factories gets a wider range of QD Bushings delivered at the proper time at the right 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 from high quality engineered components with great tolerance. The feature is certainly easy to use and needs no additional 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: complete selection of both metric and imperial available.
Standard range fits up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete brief reach range obtainable, for compact lightweight assemblies & Clean, Compact Design.
Ease of installation and removal.
The original sheave and pulley installation program 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 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 1st. Assemble key.
3. Placement 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.
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 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 face of the sheave or sprocket hub and the flange of the QD bushing to insure a reasonable cone hold and press fit.

Make use of a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and several other power transmission applications. Flanged quick-disconnect bushings include a completely split design to greatly help provide easy set up and disassembly. A tapered bushing with straight edges uses an internal screw to help drive the bushing in to 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) possess a flanged style and show a 4° taper with typical or reverse installation. They are stocked in popular completed bore sizes and minimal plain bore for customized 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 becoming set up (sheave, sprocket, etc.). Be cautious when setting up these screws. The holes with threads on the bushing are for removal only. Also be aware that the appearance of a flange on the outside of the bushing doesn’t necessarily mean it’s a QD style. Split Taper bushing also has a flange, and the two aren’t interchangeable. The QD design includes a split that continues through the flange. The Steel QD (Quick Disconnect) Type bushing offers flexible and easy installation while providing exceptional keeping power. QD Bushings are used considered the industry offering comfort and design flexibility. They are precision machined of quality Steel and are set up by tightening several 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 by using the cap screws as jack-screws. Double drilled holes are furnished in QD Bushings permitting mounting of product in the traditional or reverse positions. This enables cap screws to end up being installed through product hub or bushing flange whichever is most convenient. A significant benefit in installation, cap screws are usually inserted from the exterior where they are easily accessible. QD Bushings are available from stock with all well-known bores within the number of each size bushing.
QD Bushings feature a split tapered flange with the split central to the flange and taper.
