Taper Lock® bushings are similar to QD® style bushings in that they both utilize a split through the taper and flange to provide a true clamp on the shaft that is equivalent to a shrink fit. This type of bushing is retained to the sprocket with a series of set screws on the outside diameter of the bushing running parallel to the shaft or can be welded to the sprocket itself. With Taper Lock® bushings, there is no need for a set screw over the drive shaft key. Taper Lock® bushings offer flexibility in that they allow multiple sized bores for a single bushing size.
