Super CB Series Clutch-Brake Package

Super CB Series Clutch-Brake Package

Super CB Series combination of 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 750 RPM - depending on size. Each unit is pre-engineered and pre-assembled for easy installation. Super CB clutches and brakes provide 3 to 5 times longer life! The five sizes of Super CB clutch/brake packages offer extraordinary performance and durability for those applications requiring long life under high load, high duty cycle conditions. Thomson will retrofit standard CB-5, CB-6, CB-7, CB-8, and CB-10 models.

    Super CB Series Highlights

    • AC or DC operated - other voltages available
    • High torque to size ratio
    • Repeatable positioning within ±½°  
    • Anti-overrun feature prevents the output from running faster than the input
    • Roller bearings never need adjustment for wear
    • Load over-travel or back-up is eliminated since Super CB units lock the load in both directions when the solenoid is off
    • Heavy-duty industrial grade coils
    • High cycle rate capability
    • 1-, 2- or 4-stop collar with steel insert standard
    • Bring loads up to speed in 3 milliseconds and stop within 1.5 milliseconds
    • Reinforced plastic stop collars also available for up to 24 stop maximum
