qd bushing

Our immediate supply chain to Martin Sprockets factories gets a wider selection of QD Bushings delivered at the right 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 of high quality engineered materials with great tolerance. The feature is easy to make use of and needs no extra alteration. These bushings can fit almost all types 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 available.
Standard range suits up to 125mm/5″ shafts & Hub diameter required depends upon the application.
Complete brief reach range offered, for compact light-weight assemblies & Clean, Compact Style.
Ease of installation and removal.

Ease of installation and removal.
The original sheave and pulley mounting 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 sure the tapered cone areas 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 initial. 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 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 so that the two extra holes in the hub can be found 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. Usually do not use 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 reasonable cone hold 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 tranny applications. Flanged quick-disconnect bushings feature a completely split design 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 a key on the bushing to greatly help provide more drive.
QD bushings (in . and metric sizes) possess a flanged style and show a 4° taper with regular or reverse installation. They are stocked in well-known 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 drive the bushing in to the bore of the component being set up (sheave, sprocket, etc.). Be careful when installing these screws. The holes with threads on the bushing are for removal just. Also be aware that the looks of a flange externally of the bushing doesn’t indicate it’s a QD design. Split Taper bushing also has a flange, and both aren’t interchangeable. The QD style includes a split that continues through the flange. The Metal QD (Quick Disconnect) Type bushing offers versatile and easy set up 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 many cap screws. 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. Dual drilled holes are furnished in QD Bushings permitting installation of product in the traditional or invert 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 at all times inserted from the exterior where they are often accessible. QD Bushings can be found from stock 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 force 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.
