SF 50

SF 50

Torque Force:

Depending on contact pressure, coefficient of friction and brake disc diameter

Contact Force:
510 kN

The high capacity of the SF-series makes them particularly suitable as secondary emergency brakes on hoist gears and on downhill conveyor. Further applications are possible in material handling, requiring power and compact design in either direction of rotation, particularly in replacing band brakes.

  • Two identical caliper halves, ready for operation, with spring packs set to nominal force and limit switch release control
  • Up to 2 mm air gap between brake pad and disc
  • Easy, manual pad wear compensation
  • Sintered linings
  • Proximity switch pad wear, brake release, brake set
  • Complete piped supports for one or more calipers
  • Hydraulic power units or BUEL G®
  • Special seals for flameproof fluids
  • Cleaning pads
  • Brake discs
  • Monitoring system CMB
  • Piping set steel / stainless steel

With a single acting (SA) brake, braking force is generated in one half of the brake and the other half slides towards it using a robust, low friction system, enabling self-alignment and making it ideal for small spaces and applications with axial movement.

The SKP model disc brake is a spring applied, hydraulically released brake which offers a reliable and safe of method of braking linear or rotary motion.

The STL Systems are "multi-function" units, all contained within one interface. It is indeed a modular system that you can choose the function(s) needed. All from single, S (Stopping) T (Turning) or L (Locking) functions.

The Twin Safe is our larger torque twin disc variation of our classic reliable SFB series, used successfully on winch motors in ship building and as a safety, service or holding brake in wharf crane installations.

A retrofitable, compact electronic status indication system to be integrated into the brake as an additional device.

Hydraulic active rotor brake

A hydraulic active rotor brake with a braking force of 44 kN that’s been specially developed for use in damp, dusty and corrosive working environments

Due to its high capacity, our SFRA brake is mainly used as a rotor brake in wind turbines. It is particularly suitable for applications with a high duty cycle.
