Airflex Water Cooled Brakes are available in four different models;  WCB2, WCBD, WCS, and WCSB.  The WCB2/WCBD line was designed for applications requiring high horsepower absorption and features brakes that are air-applied.  The WCS line was designed specifically for continuous slip service, to absorb and disappate thermal loads associated with the most severe clutch and brake applications.  The WCSB line was designed for dynamic tensioning, static holding and emergency stopping in one complete brake.  This line features brakes with water-cooled and air-cooled friction discs in one brake that is both pressure and spring-applied.

Product Sizing
Water cooled element sizes are indicated by the number of friction discs and the disc diameter in inches. For instance, size 224WCB has two friction discs 24 inches in diameter.
