qd bushing

Our direct 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 constructed with high quality engineered components with great tolerance. The feature can be easy to make use of and needs no additional alteration. These bushings can fit almost all sorts of assemblies and sizes. They are the best choice in style for mechanical connections.
No costly re-boring: full range of both metric and imperial obtainable.
Standard range matches up to 125mm/5″ shafts & Hub diameter required depends on the application.
Complete brief reach range obtainable, for compact light-weight assemblies & Clean, Compact Style.
Simple installation and removal.

The initial 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) mounting configurations.
1. Be certain 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 first. Assemble key.
3. Position QD bushing on shaft. Tighten set screw over key “hand tight” with standard 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.
Notice: 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. Usually do not use extensions on wrench handles. There must be a gap between your 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 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 feature a completely split style to help provide easy set up and disassembly. A tapered bushing with straight edges uses an internal screw to greatly help drive the bushing into the shaft, while a split taper includes a flange and an integral on the bushing to greatly help provide more drive.
QD bushings (in . and metric sizes) have a flanged style and show a 4° taper with conventional or reverse installation. They are stocked in popular finished bore sizes and minimal plain bore for customized 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 drive the bushing into the bore of the component being set up (sheave, sprocket, etc.). Be cautious when installing these screws. The holes with threads on the bushing are for removal only. 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 offers a flange, and the two aren’t interchangeable. The QD design has a split that proceeds through the flange. The Metal QD (Quick Disconnect) Type bushing offers versatile and easy set up while providing exceptional keeping power. QD Bushings are utilized thought out the industry offering comfort and design flexibility. They are precision machined of quality Steel and are set up by tightening a number of cap screws. This draws the bushing in to the taper bore of the merchandise which compresses the bore of the bushing. QD bushings are often removed utilizing the cap screws as jack-screws. Double drilled holes are furnished in QD Bushings permitting installation of product in the traditional or reverse positions. This enables cap screws to be installed through product hub or bushing flange whichever is definitely most convenient. A substantial benefit in installation, cap screws are at all times inserted from the outside where they are often accessible. QD Bushings can be found from share with all well-known bores within the number of every size bushing.
QD Bushings include a split tapered flange with the split central to the flange and taper. They are used on sprockets, sheaves, and pulleys where more clamping force is required over standard bored-to-size bushings. Quick-Disconnect Bushings are essential for mounting v-belt drives, synchronous belt drives and roller chain drives.
