  • Definition: INTORQ BFK458 is an electromagnetically released, single-disc spring-applied brake. Braking torque is generated by compression springs in the absence of voltage, providing braking through friction locking. The brake is released by applying a DC voltage to create an electromagnetic field, drawing the armature plate away from the rotor.

  • Part Number Information: Part number 00397734 corresponds to a Friction Plate (or friction lining) used in the BFK458-12 brake size. The BFK458-12 size is typically associated with a 32 Nm rated braking torque for the Type N (non-adjustable torque) design. The friction plate is a key wear component responsible for the actual stopping function.

  • Brake Type: Spring-applied Single-disc Brake (Fail-Safe)

  • Size: 12

  • Nominal Torque (General): 32 Nm (for Type N)

  • Insulation Class: F Class (155∘C)

  • Operation: Designed for dry running
