In industrial power mechanics, bushings are crucial linings designed to help reduce the friction of mechanical parts. One of the common types of bushings in most industrial settings is the QD (quick detachable) model. As the name suggests, QD bushings are designed to make installation and removal easy.The bushings are constructed with a flange on the outer diameter that is used for mounting flush. It also uses a taper locking mechanism for mounting. Note that you should not mistake it with taper lock bushings
that also use the wedging action for locking on the shaft.The QD sheaves are constructed with a split that runs through the entire flange. The aim of the split is to provide extra flexibility and make installation easy and fast. To remove the bushings, the cap screws serve as jackscrews. Besides, it also helps to enhance the bushing holding power. This is the main reason why QD bushings are very common in most industrial power transmission activities.
