SF QD Type Bushings
SF QD Type Bushings
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 what your application requires before purchasing a socket
Type SF QD bushings are used in a wide range of applications and are available in a variety of bore sizes. We offer a full line of stock high quality precision QD bushings that are manufactured to be extremely durable and high strength. What sets these E bushings apart is a rigorous quality control process and high-quality materials. This allows you to always get a consistent quality product when ordering from us!

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.
Types of Bushings
There are several types of bushings. Among them, the SF6 insulating sleeve has the simplest structure and is based on composite hollow insulators. It also has several metal shielding cylinders for regulating the electric field within the enclosure and another for grounding the metal shield. In addition to being lightweight, this sleeve is also very durable, but the diameter of its shield electrode is enormous, which means particular installation and handling procedures are required.
Dismounting
Bushings are widely used in machinery with sliding and rotating shaft assemblies. They have the excellent load-carrying capacity and anti-friction properties. They are vital to many industries, including construction, mining, agriculture, hydropower, transportation, and food processing. They are easy to install and come in a variety of sizes and shapes. They are very durable and very reliable. They reduce machine wear and are less expensive than bearings.
