B. Spring-Loaded Driven Pulley:
Our standard spring-loaded driven pulley is affixed to the shaft via our interchangeable collet, as illustrated to the right.
One end of the collet is tapered to match the tapered pulley shaft, and the opposite end of the collet features a drilled and tapped hole.
The drawbolt is inserted through the pulley, and threads into the back end of the collet.
As the collet is drawn into the pulley shaft, the tapers of the collet and pulley shaft engage, and the collet locks down with a 360 degree grip on the driven shaft, and results in a truer running pulley.
Eliminating the use of setscrews, and in most instances keyway and key, pulley installation can be accomplished in minutes.
Absent the primary sources of fretting corrosion, pulley removal can likewise be accomplished swiftly, even after years of service in the field.
