Eaton Airflex Air Cooled Disc Brakes Type FHB

Industrial Clutch Parts Ltd. supply a full range of Eaton Airflex Air Cooled Disc Brakes. Available with favorable torque-to-size ratios and low-inertia friction disc assemblies. Eaton Airflex FHB is an air-cooled spring applied brake with exceptional friction life and rapid friction replacement capability.

The FHB Air Cooled Disc Brake provides exceptional friction life due to its long-wearing, organic friction material and a rugged solid cast, rotating disc that provides lower inertia than typical caliper brakes. The revolutionary floating housing concept helps provide quick change friction capability with longer friction life. 

Eaton's FHB has been purposefully built for dragline applications. The spring applied (power-off), pressure released disc brake provides equal torque in either direction of rotation. Ideal for applications with non-cyclic brake engagement that require high-speed operation or precise balance of the rotating components.

Eaton Airflex Clutches and Brakes have been designed to enhance performance. 138 FHB disc unit enables quick and easy maintenance of friction pads to reduce downtime on dragline applications. Floating Housing Brakes allow for a faster and safer installation process with an exclusive shaft lock assembly for easier mounting and removal. With virtually no wear during free-wheeling, the FHB units operate for longer.


  • Rated for over 430,000 lb‐in of torque.
  • A 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.
  • Longer friction pad wear life due to a full 360° annular disc.
