Double brake: The new component in our safe brake systems
A popular solution for implementing safe brake systems in industrial environments or in event technology applications is the use of 2 parallel motors with individual brakes – a safe but not particularly compact or cost-effective solution.
With the state-of-the-art BF../BT.. double brakes, SEW‑EURODRIVE makes it possible for you to implement a safe brake system with 2 individual brakes on one single drive. Both of these double brake designs achieve the maximum performance level e (PL e) in industrial systems and event technology applications (in theaters, for instance).
The advantages of the double brake: Less installation space, less installation work and therefore lower costs. Supplementing a safe brake system, they provide completely new possibilities for man and machine in the area of functional safety.

As well as the HR manual brake release with automatic re-engaging function that can be used to release both individual brakes in the double disk brake simultaneously, a new HT manual brake release option is also available. In addition to the basic function of the HR option, it includes a special mechanical component on the manual release lever. This allows for the release of either of the individual brakes or both of the brakes together.
The double disk brakes are available from August 2015 in sizes BF11/BT11, BF20/BT20 and BF30/BT30 and with a rated braking torque from 2 x 20 Nm up to 2 x 300 Nm.
- Manual brake release
- Contactless function and wear monitoring
- Special brake control
- Optional diagnostic unit for function and wear monitoring of the /DUE (diagnostic unit eddy current) brake
The sensor system provides continuous fully contactless function and wear monitoring for each individual brake. It displays the brake switching state, monitors the permitted wear and continuously measures the current working air gap.
