Double spring-applied brake Characteristics The powerful double spring-applied brake BFK455-28 is a redundant braking system intended for use in direct drives. Due to its flat design this brake can be easily integrated in existing drive solutions. dH7/l (bore diameter/ length) Standard 1) – Additional sizes and braking torques on request – MK: Brake rated torque in Nm in relation to n = 100 r/min – P20: Coil power at 20˚C in W – 1) Standard keyway according to DIN 6885/1-P9 – Braking torques up to 2x2065 Nm – Stable braking torque against contact surfaces with high temperature – Long-term...

Dual circuit spring-applied brake generating the braking torque acts – 80% directly on the front armature plate and – 20% indirectly via the rear armature plate The dual circuit spring-applied brake BFK454 complies Directive 2014/33/EU and EN‑81 for lift systems. The dual-circuit braking system is achieved by splitting the armature plate into two segments, the spring force for – Braking torques of up to 400 Nm – Small construction volume – Easy adjustment (reduction) of braking torque via the central adjustment ring – Simple maintenance and inspection of dual-circuit function – No splitting...

Double spring-applied brake Characteristics Double spring-applied brakes of the BFK458 series are suitable for lifts. The required redundant braking system is achieved by using individual components of the BFK458. – Braking torques of up to 2x400 Nm – Noise-reduced (optional) – Modular structure – Simple mounting using connection flange – Manual release with “one-hand-operation” INTORQ 155-1 – Additional sizes and braking torques on request – MK: Brake rated torque in Nm in relation to n = 100 r/min – P20: Coil power at 20˚C in W – 1) Predrilled, without keyway – 2) Standard keyway...

Double spring-applied brake Characteristics Double spring-applied brakes BFK457 fulfill the high demands on redundant braking systems in lifts. The switching noise is minimised by special arrangement of damping elements and achieves values of <50 dbA. – Braking torques up to 2x80 Nm – Noise-reduced < 50 dbA (armature plate and rotor) – Modular structure – Easy installation – Manual release with “one-hand-operation” INTORQ 155-1 – Additional sizes and braking torques on request – MK: Brake rated torque in Nm in relation to n = 100 r/min – P20: Coil power at 20˚C in W – 1) Predrilled, without...

Customized solutions – tailored exactly to your needs Automation solutions have become an indispensable part of industry and everyday life. In this context, it is often the brakes that ensure safety: They hold loads and brake reliably in an emergency. Just as automation continues to evolve, brakes must also face higher demands – forward-looking products are in demand. At the same time, quality and safety must be unconditionally guaranteed. This is a challenge that Kendrion Industrial Brakes meets with passion and care. When it comes to developing customer-specific solutions, we have three...
