The CDB is a clutch and brake module manufactured by Chain Tail. It is suitable for use in starting, stopping, position, and holding in high frequency applications.
The unit features a pen design for input and output power. The output and input shafts are formed by means of a bearing cam, through the attachment of a clutch rotor, and a brake to the same rotor. The motion is transmitted to the input shaft as soon as the clutch is activated. The output shaft and bearing cam separates when there is a power cut-off on the clutch.
