SDS QD Type Bushings

SDS QD Type Bushings

Bushing is a mechanical component that is essential in many different fields. In addition to being very practical, it helps reduce noise, vibration, and wear and provides anti-corrosion properties. These properties aid mechanical equipment in various ways, including making it easier to maintain and reducing its overall structure. The functionality of an enclosure depends on its purpose and environment.

The role of the bushing

Electrical bushings are an essential part of much electrical equipment. These devices carry high voltage currents while providing an insulating barrier between live conductors and metallic bodies at ground potential. Most electrical bushings are of the bulk type, consisting of a central conductive rod made of copper or aluminum and an insulator, such as composite resin silicone rubber, surrounding it. However, some types are specially made to protect against electrical failure and withstand cable loads and the thermal expansion they are subjected to.
Other applications for bushings include suspension joints and steering linkages. These components reduce the amount of road noise and vibration that drivers experience while driving. Bushings often degrade due to constant movement and exposure to heat, oil, salt, and other contaminants. Damaged bushings not only affect the performance of the steering system but can also cause noise and vibrations that annoy the driver. Therefore, they must be replaced as soon as possible.

Dismounting

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. Different designs have different applications, so you should understand your application needs before purchasing a socket.

Standard Mounting

1. Make sure the cone on the bushing and the inside of the driven product is clean and free of oil or 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 good tapered grip and press fit. NOTE: This gap must not be closed.
