BFK458-14-F Intorq BFK458 Size 14 Flange

Intorq BFK458 brake flanges are mechanical mounting components used to provide a suitable counter-friction surface and mounting interface for Intorq BFK458 spring-applied brakes in motor and machinery applications.​

Product overview

• The brake flange is used when the motor or machine does not offer a suitable counter-friction face for the BFK458 brake, allowing reliable torque transmission and correct axial positioning of the brake.​
• It forms part of the modular BFK458 system, which includes options such as friction plates, hand release, covers and other mounting accessories for configuring the brake assembly.​

Design and construction

• The flange is designed as a rigid mounting plate with a prepared friction surface matched to the BFK458 armature plate and rotor, ensuring correct contact conditions for dry-running operation.​
• Depending on the brake size and variant, the flange can be supplied in standard or hard chrome-plated versions to improve wear resistance and corrosion protection, and may be combined with a cover ring if required.​

Key functional characteristics

• Provides the defined counter-friction surface necessary for achieving the rated braking torque of the corresponding BFK458 brake.​
• Supports precise alignment of the brake relative to the shaft and hub, helping maintain the preset air gap and reducing wear on the friction linings over the service life of the brake.​

Selection notes

• Selection of the correct BFK458 brake flange requires matching the flange to the brake size, mounting pattern and any required options (such as hard-chrome friction surface or use with friction plate or intermediate flange).​
• Detailed dimensional data, permissible tolerances and mounting instructions are provided in the BFK458 documentation and should be consulted to ensure correct fit and safe operation in the intended application.​
