* Other coil voltages are available upon request.
** Kinetic power ratings are maximum values based upon limiting coil and/or bearing temperature to approximately 100°C and outside case temperature to approximately 70°C, and should not be exceeded. Actual values may vary ±50% depending on mounting, ventilation, ambient temperature, etc.
*** Although intended for coupled service, moderate overhung loads can be tolerated, depending on such operating conditions as speed, torque, and kinetic power. Published loads are calculated based upon ANSI/ABMA Std. 9:2008 and 1 x 106revolutions of life at the continuous power rating and are for reference only. Care should be taken to make certain that the shaft is properly aligned. Couplings should be of proper size and flexibility to adequately protect bearings from undue stress and shock loading.

Applications
These units are suited for tension control applications, such as wire winding, foil, film, and tape tension control. Mounted on test benches, CPB Convection Powder Brakes allow performance and reliability testing on driving elements such as electric motors, hand-held power tools, geared motors, reduction gears and hydraulic transmission systems. Other applications include load simulation for life testing on electric motors, actuators, gearboxes, power steering, and many other rotating devices and assemblies.
 
CPB 25 Tandem application

Hollow shaft CPB’s can be mounted in series, on one single shaft, to increase torque performance.  This application example shows four CPB-25BH units in series.  The resulting torque performance at rated current was 100 Nm at rated current (4 X 25 Nm = 100 Nm).
