qd bushing

Our direct supply chain to Martin Sprockets factories gets a wider selection of QD Bushings delivered at the proper time at the right price.
Taper bushing are widely used 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 components with great tolerance. The feature is certainly easy to make use of and needs no extra alteration. These bushings can suit 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 fits 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.
Ease of installation and removal.

Ease of installation and removal.
The initial sheave and pulley installation system developed to facilitate installation and alternative of components.
The QD (Quick Detachable) design offers both conventional (flange outboard) and invert (flange inboard) installation configurations.
1. Be certain 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 first. Assemble key.
3. Placement QD bushing on shaft. Tighten arranged 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 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.
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 saw cut.
5. Tighten pull-up bolts alternately and qd bushing china evenly to tightness indicated in torque table 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 grasp 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 several other power transmitting applications. Flanged quick-disconnect bushings feature a completely split design to help provide easy installation and disassembly. A tapered bushing with straight edges uses an internal screw to greatly 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 (” and metric sizes) possess a flanged design and feature a 4° taper with conventional or reverse mounting. They are stocked in well-known completed bore sizes and minimum 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, runs on the set screw to drive the bushing in to the bore of the component becoming set up (sheave, sprocket, etc.). Be careful when setting up these screws. The holes with threads on the bushing are for removal just. Also remember that the looks of a flange on the outside of the bushing doesn’t indicate it’s a QD style. Split Taper bushing also offers a flange, and both are not interchangeable. The QD style includes a split that continues through the flange. The Steel QD (Quick Disconnect) Type bushing offers versatile and easy installation while providing exceptional holding power. QD Bushings are used thought out the industry offering comfort and design versatility. They are precision machined of quality Steel and are installed by tightening many 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 utilizing 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 enables cap screws to be installed through product hub or bushing flange whichever can be most convenient. A significant benefit in set up, cap screws are often 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.
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 push is necessary over standard bored-to-size bushings. Quick-Disconnect Bushings are essential for mounting v-belt drives, synchronous belt drives and roller chain drives.
