Modular spring applied brakes INTORQ BFK458

Brakes with electromagnetic release 2 to 600Nm

The BFK458 modular system of spring applied brakes is world class and proven in thousands of different machines with torques from 2 to 600Nm.  High quality construction with long lasting materials suits use in all types of safety sensitive applications.  A cold-climate version is available for extreme ambients and this is used in wind turbines.  For mechanical handling there is a long-life variant that can achieve more than 10 million operations.  Nine sizes with CSA and UL approval are available for operation with dc voltages from 24 to 205V.

All the options:  mounting options include friction plate, mounting flange and terminal box.  Functional options are manual release, limit switches, long life, double safety brake and low noise.
Enclosure options are IP54, external seal or cover.
Brake rectifiers are available.
Brakes are designed for dry running and brake torque can be adjusted (type E).

Where the duty is mainly static holding torques, rated torques can be increased to a maximum by factory modification of the springs.
