The initial sheave and pulley installation program developed to facilitate installation and replacement 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 within of the driven item 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 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.
Notice: Install M thru S bushings in the hub so 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 make use of extensions on wrench handles. There must be a gap between your 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 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 feature 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 in to the shaft, while a split taper includes a flange and a key on the bushing to help provide more drive.
QD bushings (” and metric sizes) have a flanged style and show a 4° taper with conventional or reverse mounting. They are stocked in popular completed bore sizes and minimal 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 operate a vehicle the bushing into 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 remember that the appearance of a flange on the outside of the bushing doesn’t indicate it’s a QD design. Split Taper bushing also has a flange, and both are not interchangeable. The QD style 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 utilized considered the industry offering comfort and design flexibility. They are precision machined of quality Steel and are installed 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. Dual drilled holes are furnished in QD Bushings permitting installation of product in the traditional or reverse positions. This allows cap screws to be installed through product hub or bushing flange whichever can be most convenient. A substantial benefit in set up, cap screws are constantly inserted from the outside where they are easily accessible. QD Bushings can be found from stock with all popular bores within the range 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 drive is necessary 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 right time at the right price.
Taper bushing are widely used together with 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 usually easy to make use of and needs no additional alteration. These bushings can match almost all kinds of assemblies and sizes. They will be the best choice in design for mechanical connections.
No costly re-boring: complete selection of both metric and imperial obtainable.
Standard range fits up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete short reach range available, for compact light-weight assemblies & Clean, Compact Style.
Ease of installation and removal.
The original 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) installation configurations.
1. Be sure 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 1st. 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 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 bushings in the hub to ensure that the two extra holes in the hub are located 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. Do not make use of 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 reasonable 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 transmitting applications. Flanged quick-disconnect bushings include a completely split style to greatly help provide easy set up and disassembly. A tapered bushing with straight edges uses an internal screw to help drive the bushing into the shaft, while a split taper includes a flange and a key 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 regular or reverse mounting. They are stocked in well-known completed bore sizes and minimal 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, runs on the 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 indicate it’s a QD style. Split Taper bushing also has a flange, and both aren’t 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 used thought out the industry offering convenience and design versatility. They are precision machined of quality Metal and are installed 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 installation of product in the conventional or invert positions. This allows cap screws to be installed through item hub or bushing flange whichever is certainly most convenient. A substantial benefit in set up, cap screws are always inserted from the exterior where they are often accessible. QD Bushings can be found from stock with all well-known bores within the number of every size bushing.

They are used on sprockets, sheaves, and pulleys where more clamping drive is required over standard bored-to-size bushings. Quick-Disconnect Bushings are crucial for mounting v-belt drives, synchronous belt drives and roller chain drives.
