QD bushing, also known as quick break bushing, is a mechanical bushing used to attach pulleys, sprockets, and other components to a shaft. It is designed to provide a quick and easy way to install and remove these components without additional tools or equipment. This makes the QD casing ideal for applications requiring frequent maintenance or component replacement.


QD bushings, also known as “quick break” bushings, are used to mount pulleys, sprockets, and other power drive components to the shaft. These bushings have a tapered hole that allows them to be easily installed and removed from the shaft without the need for specialized tools.


Split Taper QD Bushings

These bushings have a split taper design, which allows them to be easily mounted and removed from a shaft. They are often used in applications where frequent component changes or maintenance is required.


Stainless Steel QD Bushings

These bushings are made from stainless steel, which provides corrosion resistance and durability in harsh environments.


Taper-Lock QD bushings

 These are a type of QD bushing that uses a locking mechanism to secure the bushing onto the shaft. They are commonly used in high power applications where a secure attachment is required.


How Does QD Bushing Work?

QD bushings work by providing a tapered hole that fits into the shaft of a power drive component such as a pulley or sprocket. The bushing is fitted to the shaft by tightening a set of screws or bolts that compress the conical hole so that it holds the shaft tightly.

Once the bushing is mounted to the shaft, the power drive assembly is mounted to the bushing using a set of screws or bolts. The bushing effectively becomes an adapter that allows components of different hole sizes to be mounted on a common shaft size.



Advantages Of QD Bushing

One of the main advantages of QD casing is that it is easy to install and remove. The bushing can be easily installed onto the shaft by sliding the bushing onto the shaft and tightening the setting screws. Flanges can then be attached to the part being installed, and the two can be joined together by mounting flanges into grooves outside the bushing. To remove the assembly from the shaft, loosen the setting screw and pull the flange away from the bushing.


Another advantage of QD bushing is its ability to provide a secure connection between the component and the shaft. The flange is designed to fit closely with the groove on the outside of the bushing, creating an active locking mechanism that prevents the assembly from sliding or rotating on the shaft.

QD bushing is also versatile and adaptable to a wide range of applications. It is available in different sizes and configurations to fit various shaft sizes and types, as well as different component mounting requirements.

The flange can be made from different materials, such as steel, aluminum, or plastic, to suit the specific application requirements.

In addition, the QD bushing provides a cost-effective solution for mounting components to a shaft. It eliminates the need for expensive keyways or other specialized machining on the shaft, which can save time and money in the manufacturing process.
