SIBRE HEROES
USB 5
Fail-safe disc brakes
USB 5
The USB5 represents the latest generation of SIBRE‘s maintenance-free failsafe disc brakes, combining spring-applied and weight-applied braking principles for superior performance. Specifically engineered for high-speed shaft applications in crane lifting and material handling, the USB5 delivers reliable dynamic and holding brake performance across a standardized platform of five brake sizes.
Enhanced design delivers improved friction stability, parallel brake shoe opening for simplified alignment, and reduced noise emission. Automatic wear compensation, synchronizing linkage, and corrosion-resistant construction ensure long service intervals and consistent performance. Sintered linings accommodate circumferential speeds up to 85 m/s and disc temperatures to 850°C.
