The original sheave and pulley mounting program developed to facilitate installation and substitute of components.
The QD (Quick Detachable) design provides for both conventional (flange outboard) and invert (flange inboard) installation configurations.
1. Be sure the tapered cone areas 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. Position QD bushing on shaft. Tighten arranged 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 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 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 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 include a completely split design to help provide easy installation 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 help provide more drive.
QD bushings (in . and metric sizes) have a flanged design and feature a 4° taper with typical or reverse mounting. They are stocked in well-known completed bore sizes and minimal plain bore for custom 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 in to the bore of the component becoming installed (sheave, sprocket, etc.). Be careful when installing 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 necessarily mean it’s a QD design. Split Taper bushing also has a flange, and the two aren’t interchangeable. The QD style has a split that continues through the flange. The Metal QD (Quick Disconnect) Type bushing offers versatile and easy installation while providing exceptional keeping power. QD Bushings are utilized thought out the industry offering comfort and design flexibility. They are precision machined of quality Metal and are set up by tightening many cap screws. This draws the bushing into the taper bore of the product which compresses the bore of the bushing. QD bushings are often removed by using the cap screws as jack-screws. Dual drilled holes are qd bushing china furnished in QD Bushings permitting mounting of product in the traditional or invert positions. This allows cap screws to become installed through product hub or bushing flange whichever is certainly most convenient. A substantial benefit in set up, cap screws are generally inserted from the exterior where they are often accessible. QD Bushings are available from share with all popular bores within the number 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 power 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 immediate supply chain to Martin Sprockets factories gets a wider range of QD Bushings delivered at the right 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 materials with great tolerance. The feature is certainly easy to use and needs no extra 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: full range of both metric and imperial available.
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.

1. Be certain the tapered cone areas 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 established screw over key “hand tight” with regular Allen wrench only. Usually 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 so that both 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 table on back. Usually do not use extensions on wrench handles. There must be a gap between the face of the sheave or sprocket hub and the flange of the QD bushing to insure a reasonable cone grip and press fit.

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 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 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 standard or reverse mounting. 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, runs on the set screw to operate a vehicle 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 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 the two aren’t interchangeable. The QD style has a split that continues through the flange. The Metal QD (Quick Disconnect) Type bushing offers versatile and easy installation while providing exceptional keeping power.

This draws the bushing into 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 end up being installed through item hub or bushing flange whichever is usually most convenient.
