Air-cooled disc clutches and brakes

Danfoss Airflex air-cooled disc clutches and brakes excel in a wide range of applications. With favorable torque-to-size ratios and low-inertia friction disc assemblies, they maximize performance in confined spaces.

Features and benefits

  • Favorable torque-to-size ratios
  • Spring- or pressure-applied multiple-disc units 

DBBS high-torque brakes

  • Spring applied
  • Air or hydraulic release
  • Designed for heat dissipation
  • Ideal for demanding non-cyclic applications

DBA disc-style brakes

  • Spring applied and pressure release
  • Solid or ventilated discs
  • Large friction areas to dissipate energy
  • Ideal for high-cyclic or high-inertia stops
  • Designed for conveyors, power shovels, and draglines

FHB floating-housing brakes

  • Air cooled, spring applied
  • Maximal safety and uptime
  • Less frequent friction changes
  • No rotor spline wear or brake adjustments 

DBB disc-style brakes

  • Spring applied
  • Air or hydraulic release
  • Ideal for cyclic applications requiring heat dissipation
  • Designed for bottling equipment, power shovels, shears, and power presses
  • Self-lubricating seals eliminate premature twisting failure

DC clutches and brakes

  • Pressure-applied 
  • Single- or multiple-disc designs 
  • Can be used as a clutch or brake
  • Self-lubricating seals eliminate premature twisting failure

Applications

  • Oil and gas drawworks
  • Mining draglines
  • Shovels
  • Conveyors
  • Presses
  • Mooring systems
