Additional Information

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.
