Floating Housing Brake

Floating House BrakeEaton’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.

Addresses these engineering challenges:

  • Rated for over 430,000 lb-in of torque
  • Patented braking concept uses a floating housing instead of a floating rotor
  • Multiple brake installation designs exist for industry leading motors
  • Fixed hub and rotor design



Product Features

  • Long-wearing organic friction material and a rugged, solid-cast rotating disc reduce inertia compared to typical caliper brakes
  • Designed to fit and interface with multiple, industry-leading motor frames
  • Fixed hub and rotor design extends product life by 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



Technical Information

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.

Additional Information

Eaton FHB Valuation Calculator
This online calculator tool will show that over time, you could limit downtime as the result of less frequent friction pad changes. The results will also reveal your overall payback of upgrading to the FHB by function and as a cumulative curve. You’ll be able to compare your current annual maintenance costs with what they would be after switching to FHB.
