SH QD Type Bushings
A bushing is a component that provides a bearing surface for the forces acting axially on the shaft. A typical example of a thrust bearing is a propeller shaft. The bushing can be a separate part of an integral part of the machine. Typically, bushings are replaceable, while integral bearings are permanent and should not be replaced unless worn or damaged. Bushings are most commonly used in machinery, where they allow relative movement between components. The bushing is usually an integral unit, while the bearing may have several parts. Simple bushings can be made of brass, bronze, or steel. It is often integrated into precision machined parts and helps reduce friction and wear. Typically, bushings are made of brass or bronze, but other materials can also be used.

1. Make sure the cone on the bushing and the inside of the driven product is clean and free of oil or any anti-seize lubricant.
2. Slide QD bushing on a shaft, flange end first, then assemble key.
3. Place the QD bushing on the shaft. Use only a standard Allen key to tighten the set screw on the key (hand-tight). Don’t push too hard.
4. Slide the large end of the sprocket or other part taper hole into place over the cone, aligning the drilled bolt holes on the sprocket or other part with the taper holes in the bushing flange. Then assemble the pull-up bolt and lock washer.
5. Tighten the pull-up bolts alternately and evenly to the tightening levels shown in the torque table below. Do not use extensions on wrench handles. There should now be a gap between the face of the sprocket or other part hub and the flange of the QD bushing to ensure a satisfactory tapered grip and press fit. NOTE: This gap must not be closed.
SH QD bushings are designed for use with QD sprockets and pulleys and are available in a variety of bore sizes. Bushings come with standard keyway diameters, so it is important to select the proper bore diameter. Once the bore diameter is determined, the customer can proceed to select the desired bushing. Sleeves are manufactured in accordance with ISO 9001 quality management standards. For easy installation and removal, SH QD bushings are designed to mate with PLI QD sprockets.
A good bushing should be free of oil and any anti-seize lubricant. It should then be installed on the shaft with the flange end down. Next, install the sprocket on the bushing, aligning the big end with the bushing. Finally, drill holes and install the pull-up bolts. SH QD bushings are available in metric and splined bores.
