WCBD Disc Brake Elements On The Rowland Company

WCB elements are disc type, externally cooled units. They are designed to absorb and dissipate the thermal loads associated with the most severe clutch and brake applications. The WCB friction couple was developed specifically for continuous slip service and has a dynamic coefficient of friction that is greater than its static coefficient of friction. Also available, special high coefficient linings, which provide 50% higher torque than standard friction linings and provide a 1:1 dynamic to static torque ratio. Element construction and operation is illustrated. Pressurizing the cylinder causes the piston to clamp the friction disc between the water jackets. Heat generated at the friction interface is quickly transferred to the circulating coolant. Element sizes are indicated by the number of friction discs and the disc diameter in inches. For instance, size 224WCB has two (2) friction discs 24 inches in diameter.
