FHB BRAKES

Eaton Airflex’s FHB brake uses a patented floating housing design in place of the usual floating rotor. This air-cooled disc brake is spring applied and pressure released. It’s particularly well suited for heavy-duty industrial applications like those found in surface mining and oilfield machinery.

Torque range: 288,000 to 432,900 lb-in (32,540 to 48,918 Nm)
Typical applications: Dragline hoist, drag, swing, and propel/walk

Features

Large friction area.

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

Minimal adjustment required for lining wear.

Single disc units require no wear adjustment and dual disc units require only one wear adjustment during the long life of the friction material.

Benefits

Ability to quickly change the friction pads reduces down time on dragline from 3 hours to 1 hour Reduced maintenance cost with elimination of spline tooth or gear wear Longer friction pad wear life due to a full 360º annular disc Faster and safer installation with exclusive shaft lock assembly for ease of mounting and removal Virtually no wear during free wheeling, allows high product life
