P QD Type Bushings

The QD bushing is a split tapered flange bushing typically used on sprockets and gears. It has a flange that attaches the bushing to the sprocket, usually installed with cap screws. Since the QD bushing is separated by its flange, it can accommodate small differences in shaft diameter. QD bushings are interchangeable between manufacturers and can be used in a variety of applications.

QD bushings are also compatible with other rotating equipment. They are designed with 6 mounting holes and come with a bolt that can be mounted from either side. A “quick release” bushing is similar, but it has a removable cap screw and removal hole. Removing the QD bushing is as easy as removing the capscrews. All you have to do is loosen the cap screw and tap the hub of the sprocket to loosen the bushing.

What you should know about a bushing

If you’re in the market for a bushing, there are a few things you should know before buying. First, bushing is a mechanical part with a rotating or sliding shaft part. You can find them in almost all industrial applications due to their excellent load-carrying capacity and anti-friction properties. They are essential in construction, mining, agriculture, hydropower, material handling, and more.

Dismounting

The most common uses of plain bearings are in critical applications, including turbines and compressors. They are also commonly used in low-speed shafting, including propeller shafts and rudders. These bearings are very economical and suitable for intermittent and linear motion. However, if your application does not require continuous lubrication, a plain bearing may not be required. Another popular use for sleeves is in food processing. These bearings can be made from a variety of materials, including stainless steel and plastic. Plastic bearings are more cost-effective than metal and are an excellent choice for high-speed applications. These materials are also resistant to corrosion and wear. However, despite their high cost, they can be made from a variety of materials.

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.
