The CR-Series Tiny-Clutches are captured roller and cam assemblies that are installed in the housing. As they are designed to be built into the user's equipment, loose parts are eliminated and work is enhanced. The clutches use a proven cam and roller principle for a trouble-free performance. They employ a positive operation type which results in a no-slip driving action. A near zero backlash is also featured in the clutches, thus keeping them from jamming when used in a free direction. The instruments are made with free-wheeling speeds that last a long service life, as well as positively-oriented retainers which are fastened to the cam. The clutches are available in five models which work in maximum speeds that range from 4500 RPM to 7000 RPM.
