Trantorque(reg) QC(TM) is a tapered keyless bushing from Fenner Drives that simplifies the installation and positioning of synchronous belt sprockets bored for QD bushings, the company says. Directly interchangeable with the QD bushing, Trantorque QC is available in bore sizes ranging from 1/2 inch to 2 1/4 inches, depending on the series. The bushing uses a single locking nut to draw a tapered outer sleeve against a tapered inner collet.
