Super CB Series
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
