No-slip clutch/brakes keep loads and drives synced up. Machines that move loads to specified positions and hold them within a few thousandths of an inch need highly controllable, precision brakes.

In automatic transmissions a smooth clutch operation is related to the velocity dependence of the coefficient of friction (COF). Although JASO M348 and other full-scale clutch tests, or other ...
