INTORQ BFK458-12-00743258 a spring-actuated single disc electromagnetic brake
General Applications: INTORQ BFK458 series is used wherever moving masses must be decelerated as quickly as possible or held in a defined position. Versatile modular structure allows for adaptation to almost any application.
Industrial Sectors: Particularly favored in all areas where a fail-safe stop is mandatory, such as brake motors, cranes, hoisting and transport systems, warehousing technology, escalators, and woodworking machinery.
Safety Function: Acts as a safety brake in case of power failure, preventing the load from dropping or uncontrolled machine movement. These brakes are certified for both service and holding brake functions.
Definition: INTORQ BFK458 is a single-disc, spring-applied electromagnetic brake. Braking torque is generated by springs when power is de-energized. Releasing (opening) brake occurs when DC voltage is applied, and the magnetic field overcomes the spring force.
Part Number Information: Size BFK458-12 is associated with a nominal torque of 32 Nm. Part number 00743258 typically corresponds to a complete magnetic coil part (Stator) for the BFK458-12 N (non-adjustable torque) brake. Magnetic part is the electrical component that enables the brake release. Coil voltage for this size is commonly a standard value like 103 V DC or 24 V DC.
