Cam & Ring Assembly
Also known as a roller ramp clutch assembly, a cam & ring assembly gives machinery extreme reliability at a low cost.
Cam & ring assemblies are a two-part system of a spring and roller with an optional thick cover that can be attached to one or both sides of the rim. The simple construction of this clutch functions in a number of applications:
- An indexing element in sewing machines, printing presses, and agricultural machinery
- An overrunning clutch for starters, ventilators, and turbines
- A backstop for drilling plants, conveyors, and electric motor applications
- A switchback or disconnection device for amusement park rides
