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
