BFK552 spring-applied brake

Compact, powerful, reliable – specifically for logistics applications

The compact BFK552 spring-applied brake has been designed for use in stacking lift trucks and aerial work platforms, but it is also suitable for other applications where there is limited installation space. As a fully installable unit, this brake saves time during mounting and augments safety.

Function description:

This brake is an electrically releasable spring-applied brake with a rotary brake disk that is outfitted with friction linings on both sides (rotor). In a deenergised state, the rotor is tensioned between the armature plate and a counter friction face by a braking normal force applied by compression springs. Hence, its function corresponds to the fail-safe principle.

The braking torque applied to the rotor is transmitted to the drive shaft via a toothed hub.

The brake can be used as a holding brake and for emergency stops from high speeds.

The asbestos-free friction linings ensure a reliable braking torque and low wear.

In order to release the brake, the armature plate is lifted off the rotor electromagnetically (release). The rotor, which is axially displaceable and thereby relieved of the spring pressure, can turn freely.

Areas of application:

• Industrial trucks
• Intralogistics
• General motor applications

Product features:

• Flat, compact design – requires less installation space and low dead weight
• 3 sizes
• Braking torque from 15 to 180 Nm
• Stable braking torque throughout its entire service life
• Water and dust protection in accordance with IP66 (w/o manual release)
• Longer maintenance interval thanks to lower wear
• Fully installable unit – prevents mounting errors and reduces mounting time
