1. Introduction
Warner Electric’s CB and Super CB Wrap Spring
products incorporate all the necessary
components to accurately start and stop a load
driven by a continuously rotating input. Each unit
has been engineered to be a preassembled
package, consisting of a clutch and a brake with
a stop collar and solenoid actuator affixed to a
backing plate. Both the CB and Super CB are
capable of locking the load in both directions so
no external anti-back or overtravel mechanism is
required to maintain registration.
Failure to follow these
instructions may result in product damage,
equipment damage, and serious or fatal
injury to personnel.
