When you need a precise balance of rotating components you can trust the superior performance of Eaton Airflex DBBS disc style brakes. These spring-applied with air-released or hydraulically-released brakes are designed to dissipate heat.

Eaton Airflex DC Disc-style

Feature Of Eaton Product

• With split friction discs options to simplify maintenance allows friction discs to be removed worrying about other components of the drive system
• Low-inertia friction disc assembly for improved reliability reduces the overall inertia
• Torque capacities up to 2,061K lb•in (233,000 N-m) to equalize torque in both directions of rotation
• Available in a wide range of standard sizes

Engineering

Eaton Airflex DC clutches and brakes provide the same torque capacity in a smaller package. The DC Clutches have either a single- or multiple-disc design, featuring long-wearing, self-lubricating PolyPak seals that eliminate premature failure from twisting. They excel in applications from power presses and tension brakes to emergency stop brakes on unwind stands and clutches on metalforming applications.

Eaton Airflex Water-Cooled Third Generation Brake
