    INTORQ BFK458-12 is an electromagnetically released spring-applied brake with a modular design. It is Size 12 and typically refers to a standard configuration, often of the N-type (non-adjustable torque). Spring-applied brakes are used wherever masses in motion have to be decelerated as quickly as possible or where masses must be held in a defined position. Braking force is applied by compression springs, meaning braking torque remains available through friction locking in the de-energised status (even in case of mains failure). This is a single-disc brake designed for dry running, noted for its high reliability, long service life, and low maintenance.
  • Braking Torque (Rated): 32 Nm (typical value for N-type)

  • Rated Coil Voltage (DC): Standard voltages like 24 V, 103 V, 180 V, 205 V are available (specific voltage depends on the full code).

  • Insulation Class: F (155C)

  • Protection Class: Up to IP55 (depending on operating conditions)

  • Design: N (Non-adjustable Braking Torque) or E (Adjustable Braking Torque)

  • Air Gap: Preset

  • Duty Cycle: Designed for 100% duty cycle.
