The Eaton WCBD Disc Brake Elements are specially designed for heavy-duty clutch and brake applications, providing exceptional heat absorption and dissipation. Featuring a unique friction couple for continuous slip service, these units offer superior torque performance and rapid heat transfer to circulating coolant. With options for high coefficient linings and rapid heat dissipation, they ensure reliability in demanding environments such as drilling rigs, marine mooring systems, and tension brakes. The patented piston design, split wear spacers, and compatibility with open or closed loop coolant systems make these elements versatile, efficient, and cost-effective for industrial applications.

Features 0
Patented piston designSingle or dual piston provides wider range of applied tension with greater control.Drop in powerhead packageStandard single piston elements can be retrofitted with a dual piston powerhead to provide increased control.Split wear spacersThe split wear spacers allow for wear adjustment without disassembly of the brake to minimize downtime and maintenance costs.Unique friction coupleA specially formulated friction material, interfacing with a copper alloy surface, eliminates the stick-slip characteristic associated with ordinary frictional devices.Rapid heat dissipationThe copper interface conducts heat rapidly to the circulating coolant.Open or closed loop coolant systemsThe element works equally well with open or closed loop circulating systems. On mobile equipment, the engineâs cooling system can be tapped to provide coolant to the element.Optional corrosion protectionFor marine environment applications, protective coatings are available to minimize corrosion
General Description 0
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.
Note 0
Basic part number only.Order gear separately.Some high torque applications of three or four disc elements require additional torsonial support on the cylinder end of the unit. Contact your Airflex representative for more details.
