The DBF 320 is a spring applied, hydraulically released, heavy-duty industrial fixed caliper disc brake.

Advantages of this industrial brake include its fast response time, its very high max torque output, and its adjustable air-gap, which allows you to fine-tune your braking process by providing adjustable torque output. Its high temperature load capacity also makes it a great brake for high torque emergency stops.

When compared to a comparable floating caliper brake, fixed caliper brakes like the DBF are ideal for applications with minimal space constraints. In situations where lateral space is limited, consider a comparable floating caliper model, like the DBF S product line.

Traditionally, the DBF is commonly used on large hoists and cranes in ports, steel mills, and mining applications, but it is highly versatile and can be used as a safety or emergency brake in a wide range of demanding applications.

Hindon provides comprehensive service and support for DBF brakes, including technical/application engineering, as well as repair services.
