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 ...

Model DBB 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 DBB uses a conventional piston design to release the brake discs.
The rotating component of the DBB style brake is a very low inertia friction disc core with riveted on friction discs. The low inertia of the rotating components coupled ...

Wichita Spring-Set Air Release Brakes are ideal for fail safe protection of process equipment. Constructed of high strength cast iron, this improved design has thick friction discs for longer wear life. The fast acting airtube design assures quick, smooth stops.
Wichita Low Inertia clutches and brakes are air applied, spring released disc style units that develop torque proportional to the air pressure applied. The units are designed to be free from effects of centrifugal force and self-energization. Low inertia start/stop parts reduce acceleration times which allows more cycles per minute as well as reducing heat generated.
Torque – 3,160 to 17,850,000 in-lbs Applications – Presses, Shears, Bulk Material Handling and General Industrial Equipment
Wichita Clutch Standard Vent clutches are designed for reliable in-line power transmission. The simple air-tube design, with small air volume, speeds engagement and disengagement. It is ideally suited for large inertia loads where smooth controlled starts are needed.

Type DC elements can be used as either pressure actuated clutches or brakes. They are available in single and multiple disc designs.
Pressurizing the cylinder causes the piston to clamp the friction disc assemblies between clamping plates. External springs ensure positive disengagement.
Type DC elements are available in five basic disc sizes with static torque ratings to 2,061,000 lb.in (233.000 N.m). Element sizes are indicated by the number of friction discs and by the disc diameter in inches. For instance, size 225DC has two friction discs 25 inches in diameter.
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 air cooled spring applied brake with exceptional friction life and rapid friction replacement capability. It is supplied with long wearing, organic friction material and a rugged solid cast, rotating disc that provides lower inertia than typical caliper brakes.
Technical Introduction
The FHB brake is offered for applications with non-cyclic brake engagement that require higher speed operation or precise balance of ...
