qd bushing

Our immediate 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 constructed with high quality engineered materials with great tolerance. The feature is certainly easy to use and needs no extra alteration. These bushings can suit almost all kinds of assemblies and sizes. They are the best choice in design for mechanical connections.
No costly re-boring: complete range of both metric and imperial available.
Standard range fits up to 125mm/5″ shafts & Hub diameter required depends on the application.
Complete brief reach range offered, for compact lightweight assemblies & Clean, Compact Design.
Simple installation and removal.

The original sheave and pulley installation system 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 certain the tapered cone surfaces 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 1st. Assemble key.
3. Placement QD bushing on shaft. Tighten arranged screw over key “hand tight” with regular 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.
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 desk on back. Do not make use of extensions on wrench handles. There must 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 SHOULD 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 feature a completely split style to help provide easy set up and disassembly. A tapered bushing with straight edges uses an interior screw to help drive the bushing in to the shaft, while a split taper has a flange and a key on the bushing to 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 qd bushing china completed bore sizes and minimal plain bore for custom reboring.
Many people make reference 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, runs on the set screw to operate a vehicle the bushing in to the bore of the component getting installed (sheave, sprocket, etc.). Be cautious when installing 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 indicate it’s a QD design. Split Taper bushing also has a flange, and the two aren’t interchangeable. The QD design has a split that continues through the flange. The Metal QD (Quick Disconnect) Type bushing offers flexible and easy installation while providing exceptional keeping power. QD Bushings are used considered the industry offering convenience and design versatility. They are precision machined of quality Steel and are set up 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 often removed by using the cap screws as jack-screws. Dual drilled holes are furnished in QD Bushings permitting mounting of product in the conventional or reverse positions. This allows 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 at all times inserted from the exterior where they are easily accessible. QD Bushings are available from share with all popular bores within the range of every 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 crucial for mounting v-belt drives, synchronous belt drives and roller chain drives.
