Low Inertia Clutches and Brakes

Wichita Low Inertia clutches and brakes are air applied, spring released disc style units that develop torque proportional to the air pressure applied. The units are designed to be free from effects of centrifugal force and self-energization. Low inertia start/stop parts reduce acceleration times, which allows more cycles per minute, as well as reducing heat generation.
