The split tapered flange on a QD bushing creates a strong clamping force on the shaft. This kind of bushing can be interchangeable across different manufacturers, and is most often used on pulleys and sprockets. They are available in fifty-percent-inch to 1-inch dimensions.
The main benefit of this style of bushing is its quick-release ability. and QD style bushings are commonly used in Power Transmission Drives.
