Components of the spring-applied brake BFK464-

R

3.1.1

General information

The spring-applied brake is designed for converting mechanical work and kinetic energy into heat energy. 

Due to the static braking torque, loads can be held at standstill. Emergency braking is possible at high speed 

of rotation. The wear increases as the switching energy increases (operating speeds 

 18).

The BFK464 spring-applied brake is a single-disc brake with two friction surfaces. The braking torque is ap-

plied through two separate braking circuits, both electrical and mechanical, via several compression springs 

in the form of generated friction. The brake circuits are released electromagnetically. Due to its division into 

two brake circuits, the brake is particularly suitable for applications such as lift systems and stage/platform 

machinery. The brake can be selected based on the rated torque for one brake circuit. The second brake 

circuit meets the requirement for redundancy.
