Standard CB Series

Standard CB Series

CB Series combination clutches and brakes accurately start and stop loads driven by a continuously rotating power source. CB units operate from a single AC or DC pulse, stopping the load within ±½° noncumulative at speeds up to 1800 RPM. Each unit is preengineered and pre-assembled for easy installation.
