DBA Specifications

Single-disc units require no wear adjustment and dual-disc units require only one wear adjustment during the long life of the friction material
Static torque capacities up to 386,630 lb•in (43.050 N•m) equalize torque in either direction of rotation
Available in a wide range of standard sizes: 117DBA, 217DBA, 121DBA, 221DBA, 129DBA, 229DBA, 329DBA

DBA Overview

Draglines, power shovels and conveyors are just a few examples of machinery that require high-cyclic or high-inertia stops—exactly where Eaton Airflex DBA disc-style brakes excel. Featuring large friction areas to absorb and dissipate energy, Eaton Airflex DBA brakes are available as spring-applied and air- or hydraulically-released, with either solid or ventilated discs to match the speed of the application.

DBB Specifications

Optional split friction discs simplify maintenance by allowing friction discs to be removed without disturbing other components of the drive system in mid-shaft brake arrangements
Low-inertia friction disc assembly improves reliability by reducing the overall inertia that must be stopped
Static torque capacities up to 2,535,750 lb•in (286.524 N•m) equalize torque in either direction of rotation
Available in a wide range of standard sizes: 109DBB, 209DBB, 309DBB, 115DBB, 215DBB, 120DBB, 220DBB, 320DBB, 420DBB, 125DBB, 225DBB, 325DBB, 425DBB, 138DBB, 238DBB, 338DBB, 438DBB

DBB Overview

Eaton Airflex DBB disc-style brakes are the ideal solution for cyclic applications—bottling equipment, power shovels, shears and power presses—where heat dissipation is critical. Spring-applied and air- or hydraulically-released, these brakes feature long-wearing, self-lubricating PolyPak seals to eliminate premature twisting failure.

FHB Specifications

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

FHB Overview

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.
