					Super CB Series Clutch/Brake Packages
Longer Life, Extra Performance, Solenoid Operated Units
High torque in small package. Actuating solenoid is AC or DC operated. Brake engages automatically when de-clutched. Maintenance-free self-lubricating hubs are 18% oil by volume. Hardened thrust washers on input and brake end. Sintered metal hub offers easy machining for custom drive attachments. Hardened and ground shaft. Hub mounting holes for simple pulley or sprocket mounting. Hardened crossover points on input, output and brake hubs provide increased life. Steel tip insert on control cam collar. Single or multi-stop collars control rotation, ± 1/2° stop repeatability.

Super 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 ±1/2° noncumulative at speeds up to 750 RPM, depending on size. Each unit is pre-engineered and preassembled 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. Will retrofit standard CB-5, CB-6, CB-7, CB-8, CB-10.
