Eaton’s passion for developing revolutionary new disc brake technology led to the development of the Floating House Brake (FHB)—a patented braking concept that uses a floating housing instead of a floating rotor. Rated for over 430,000 lb-in of torque, these spring-applied, air-cooled disc brakes are commonly used in applications like surface mining, oilfields and other heavy-duty industrial machinery. The Airflex FHB both maximizes friction life and offers a rapid friction replacement capability.
- Supplied long-wearing organic friction material and a rugged, solid-cast rotating disc reduce inertia compared to typical caliper brakes
- Multiple available brake installation designs fit many industry-leading motors
- Fixed hub and rotor design extends product life by virtually eliminating wear during free-wheeling
- 360 degree annular disc reduces overall maintenance downtime by extending the life of friction pads, which are also easier to change
- Exclusive shaft lock assembly improves installation speed and safety
The FHB brake is offered for applications with non‐cyclic brake engagement that require higher speed operation or precise balance of the rotating components is required. It uses a solid rotor and stationary friction material to develop equal torque in either direction of rotation. The disc is mounted on the shaft which is to be stopped while the brake assembly is attached to the machine frame. Pressurizing the brake compresses the brake springs and withdraws the clamping force from the brake disc so the shaft can rotate freely. As air pressure is exhausted, the springs force the pressure plate towards the mounting flange and the spring housing which in turn forces the floating plate away from the mounting flange, clamping the disc and the friction pad assembly.
