Eaton Floating Housing Brake

Product catalog summary

Overview
Eaton Airflex has introduced the Floating Housing Brake (FHB), a new design in disc brake technology. This spring-applied, air-cooled brake is ideal for heavy-duty applications such as Surface Mining and Oilfield machinery. It features a long-lasting organic friction material and a solid cast rotating disc with lower inertia compared to typical caliper brakes.

Features and Benefits

Rated for over 430,000 lb-in of torque.
Patented design with a floating housing instead of a floating rotor.
Multiple installation designs for leading motors.
Quick friction pad changes reduce downtime from 3 hours to 1 hour.
Reduced maintenance costs due to the elimination of spline tooth or gear wear.
Longer friction pad life with a 360° annular disc.
Faster and safer installation with a shaft lock assembly.
Minimal wear during free wheeling, enhancing product life.

Technical Introduction
The FHB brake is suitable for non-cyclic brake engagement applications requiring high-speed operation or precise balance. It uses a solid rotor and stationary friction material to develop equal torque in both rotation directions. The brake assembly is attached to the machine frame, and pressurizing the brake allows the shaft to rotate freely.

Typical Applications

Draglines: Hoist, Drag, Swing, Propel/Walk
Motor frame compatibility: GE820/822, P&H 8412D, GE824/826, Siemens BI348

Airflex FHB brake elements These spring-applied, pressure released, disc style brakes develop equal torque in either direction of rotation. The revolutionary floating housing concept helps provide quick change friction capability with longer friction life than traditional caliper brakes. Overview Eaton Airflex® has introduced a revolutionary new design in disc brake technology called the Floating Housing Brake (FHB). The spring applied (power off), air-cooled disc brake is well suited for applications in Surface Mining, Oilfield and other heavy-duty industrial machinery designs. The FHB is an...

Airflex FHB brake elements Technical introduction 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. Dynamic Torque* Pressurizing the brake compresses the brake springs and withdraws the clamping force from the brake disc so the shaft can rotate freely....
