INTORQ BFK457-08 Basic spring brake
General mechanical engineering applications where rapid deceleration or controlled holding of masses is required.
Safety brake and holding brake functions in electric motors.
Simple applications requiring core braking functionality, such as in small motors, wood-working machines, and automation systems.
Special vehicle applications like vehicles for disabled persons and light conveyance systems.
Applications requiring continuous braking torque even in event of a power failure.
Product is Basic type, size 08 of INTORQ's BFK457 series of spring-applied brakes.
Electromagnetically released, this brake automatically applies friction-locking braking when power is interrupted via compression springs (fail-safe design).
Basic design typically comprises only stator and complete rotor components, and does not include integral fixing screws, distinguishing its mounting from Compact version.
Offers easy installation with its compact dimensions and a fixed air gap, and is designed for 100% duty cycle.
