2. Slide the QD bushing on shaft, flange end first, then assemble key.
3. Position the QD bushing on the shaft. Tighten the set screw over the key (hand tight) with a standard Allen wrench only. Do not use excessive force.
4. Slide the large end of sprocket or other part taper bore into position over the cone aligning drilled bolt holes in the sprocket or other part with tapered holes into flange of bushing. Then assemble the pull-up bolts and lock washers.
5. Tighten pull-up bolts alternatively and evenly to tightness indicated in the torque table below. Do not use extensions on the 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 insure a satisfactory cone grip and press fit. Caution: this gap must not be closed.
Dismounting
1. Remove all pull-up bolts and screw them into tapped holes in sprocket or other part, against flange of QD bushing to break the cone grip.
2. Loosen set screw and slide QD bushing from shaft.

Can I get recommendations for QD bushings with corrosion-resistant properties for outdoor applications?
When it comes to outdoor applications where corrosion resistance is a concern, there are several QD (Quick Disconnect) bushing options available that offer enhanced protection against corrosion. Here are some recommendations for QD bushings with corrosion-resistant properties suitable for outdoor applications:
- Stainless Steel QD Bushings: Stainless steel QD bushings are highly recommended for outdoor applications due to their excellent corrosion resistance. They are resistant to rust and can withstand exposure to moisture, humidity, and various weather conditions. Stainless steel QD bushings are available in different grades, such as 304 and 316 stainless steel, each offering varying levels of corrosion resistance. These bushings are commonly used in outdoor equipment, such as agricultural machinery, construction equipment, and outdoor conveyors.
- Plated or Coated QD Bushings: Some QD bushings are coated or plated with corrosion-resistant materials to enhance their durability in outdoor environments. Common coatings include zinc plating, nickel plating, or epoxy coatings. These coatings provide a protective barrier against moisture, chemicals, and atmospheric conditions, reducing the risk of corrosion. Plated or coated QD bushings are suitable for a wide range of outdoor applications where moderate corrosion resistance is required.
- Polymer or Composite QD Bushings: Certain QD bushings are constructed using polymer or composite materials known for their inherent corrosion resistance. Materials such as nylon, reinforced polymers, or composite alloys can provide excellent resistance to moisture, chemicals, and UV exposure. Polymer or composite QD bushings are lightweight, non-conductive, and often self-lubricating, making them suitable for outdoor applications where corrosion resistance, low friction, and electrical insulation are essential.
- Aluminum QD Bushings: While aluminum is not as corrosion-resistant as stainless steel, it can still provide satisfactory performance in certain outdoor applications. Aluminum QD bushings are lightweight, have good mechanical strength, and offer moderate resistance to corrosion. They are commonly used in equipment and machinery where weight reduction is a priority, such as outdoor recreational vehicles, lawn and garden equipment, or portable machinery.
When selecting QD bushings with corrosion-resistant properties for outdoor applications, it is important to consider the specific environmental conditions, exposure to chemicals, temperature variations, and the severity of corrosion factors. Consulting with QD bushing manufacturers or industry experts can provide valuable insights and recommendations based on their knowledge and experience.
Lastly, regardless of the corrosion-resistant properties of the QD bushings, it is important to follow proper maintenance practices and regularly inspect and clean the bushings to ensure their long-term performance and effectiveness in outdoor environments.
By choosing QD bushings with corrosion-resistant properties appropriate for outdoor applications, you can enhance the durability and reliability of your equipment, reducing the risk of premature failure and minimizing maintenance requirements.
What is a QD bushing, and how does it differ from other types of bushings?
A QD (Quick Disconnect) bushing is a type of bushing used for mounting components on a shaft in power transmission applications. It provides a reliable and efficient connection between the shaft and the mounted component, such as pulleys, sprockets, or sheaves.
QD bushings differ from other types of bushings in their design and installation method. Here are some key characteristics and differences of QD bushings compared to other types of bushings:
- Design: QD bushings typically consist of a flanged bushing with one or more tapered grooves on the inner circumference and a corresponding taper on the outer surface. The flange provides axial support for the mounted component, while the tapered surfaces enable a tight and secure fit onto the shaft. The taper design allows for easy installation and removal of the bushing with minimal effort.
- Installation: Installing a QD bushing involves a straightforward process. The bushing is placed over the shaft and positioned at the desired location. As the bushing is tightened, the tapered surfaces create a wedging action that securely locks the bushing onto the shaft. This installation method eliminates the need for additional components like set screws, keys, or locking devices. It provides a reliable and self-centering connection that minimizes shaft slippage and ensures efficient power transmission.
- Adjustability: QD bushings offer adjustability, allowing for precise positioning of the mounted component along the shaft. By adjusting the position of the bushing, the axial location of the mounted component can be easily modified, enabling fine-tuning of the power transmission system.
- Compatibility: QD bushings are designed to be compatible with a wide range of shaft sizes. They are available in various sizes and configurations to accommodate different shaft diameters and tolerances. This versatility makes QD bushings suitable for a variety of applications across different industries.
- Removability: One of the key advantages of QD bushings is their quick disconnect feature. When it becomes necessary to remove or replace the mounted component, the QD bushing can be easily released by loosening the tightening bolts. This allows for efficient maintenance and replacement without the need to disassemble the entire power transmission system.
Overall, QD bushings offer a reliable, adjustable, and user-friendly solution for mounting components on shafts in power transmission applications. Their unique design and installation method make them a popular choice in various industries where efficient and secure power transmission is required.
