The Eaton-Airflex Model 329DBAV Disc Style Brakes are designed for high-demand applications, offering equal torque in both rotation directions. These spring applied, pressure released brakes feature large friction areas to absorb high energy loads, ideal for machinery like can making machines, draglines, and power shovels. With minimal adjustment needed for lining wear and the ability to customize torque with varying spring configurations, these brakes ensure reliable performance and long-lasting durability.

Large friction area.Allows brakes to absorb and dissipate high energy loads associated with high cyclic and high inertia stops.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.
General Description 0
Model DBA brakes are spring applied, pressure released, disc style brakes. They develop equal torque in either direction of rotation. Their torque and thermal capacities allow them to be used in the most demanding applications.Brake construction and operation is shown in the figure. Pressurizing the brake compresses the brake springs and withdraws the clamping plates from the brake discs. Standard brakes are furnished with either one or two discs, which are free to move axially.Model DBA uses a rubber diaphragm to form the releasing pressure chamber and to serve as the releasing piston. Brake friction material is attached to stationary components. Brake discs are either solid or ventilated. The disc type is indicated by an S for solid, or V, for ventilated, in the brake model designation. Solid discs are used in applications requiring a heat sink and/or where engagement is infrequent. Ventilated discs are recommended for cyclic applications.Torque ratings listed are for brakes with a standard compliment of springs. The quantity of springs can be varied to customize the torque of the brake to suit a particular application. Consult the factory for brake torque of units with nonstandard spring configurations.Brake sizes are indicated by the number of brake discs and the disc diameter in inches. For instance, size 229DBA has two discs 29 inches in diameter.
