Water-cooled brakes
Danfoss Airflex water-cooled brakes are designed to meet the needs of even the most extreme applications. Our advanced design features address requirements such as high horsepower absorption, continuous slip service, thermal load dissipation, dynamic tensioning, static holding, and emergency stopping.
WCB3 Water-cooled brake
- 746 kW [1,000 hp] per disc offers faster tripping time and allows brake downsizing
- Robust design eliminates copper cracking
- Self-supporting brake eliminates costly support brackets
- Higher coolant flow with 60% lower pressure drop
WCB2/WCBD Disc-type externally cooled brake
- Special high-coefficient linings deliver 50% more torque
- Dynamic coefficient of friction is greater than its static coefficient of friction
- Optional dual-piston design improves control
- Thermal capacities up to 3,878 kW [5,200 hp]
- Torque capacities up to 819,027 Nm [7,254,450 lb-in]
WCS Externally cooled spring-applied brake
- Dynamic coefficient of friction is greater than its static coefficient of friction
- 1:1 dynamic-to-static torque ratio
- Thermal capacities up to 1,939 kW [2,600 hp]
- Torque capacities up to 174,431 Nm [1,545,000 lb-in]
WCSB Air-applied water- and air-cooled multiple-disc brakes
- Incorporates both a water-cooled brake and an air-cooled brake
- Provides dynamic tensioning, static holding, and emergency stopping capabilities
- Eliminates the need for multiple brake systems
- Materials reduce or eliminate stick-slip effects
- Thermal capacities up to 2,908 kW [3,900 hp]
- Torque capacities up to 571,119 Nm [5,058,625 lb-in]
