NORDBORG, DENMARK — Danfoss Power Solutions today announced the launch of its Airflex® ACB-F3 Failsafe Caliper Brake. The spring-applied, hydraulically released brake is engineered for optimal safety, durability, and serviceability. A new solution for park-and-hold or emergency stop applications, the Airflex ACB-F3 is ideal for the oil and gas, mining, marine, processing, and metals industries.
The Airflex ACB-F3 Failsafe Caliper Brake features a robust yet compact design that provides reliable, stable braking torque. Its symmetrical opposed piston caliper design is well suited for high-torque, high-energy stopping applications. With approximately 50% greater lifetime than competitive products, the brake’s friction pads ensure safe and stable torque over a longer duration. The large pad surface enables high thermal dissipation.
The Airflex failsafe brake offers simple installation and maintenance. With a modular design that fits various disc configurations and enables custom braking torque, the brake is easily installed and set in new and existing systems. Its modularity also simplifies the installation of multiple calipers around one disc to achieve the required braking torque. The brake’s primary maintenance needs — replacement of friction pads, seals, and springs — can be performed without removing the caliper from its installation position, minimizing system downtime. The caliper also simplifies wear compensation, making it easier to maintain the original braking force. Optional wear and engagement sensors enable remote monitoring and increase safety.
“Our new Airflex failsafe caliper brake leverages nearly 90 years of engineering expertise to provide superior performance in park-and-hold and emergency stop applications,” said Giovanni Taverna, Product Manager, Airflex Brakes and Clutches, Danfoss Power Solutions. “The ACB-F3 is the central model of this new series, with additional frame sizes coming soon to meet the needs of a range of applications.”
The ACB-F3 features a clamping force of 20 to 120 kN and a braking force of 16 to 96 kN. Release oil pressure ranges from 40 to 190 bar (580 to 2,756 psi). The brake is available with organic or sintered friction pads. An anti-corrosion version is available for use in extreme environments. Ideal applications include mining conveyors, grinding mills, hoists, drilling drawworks, marine winches, cranes, and other heavy-duty equipment.
Complete braking solutions are available by combining the new failsafe brake with a Vickers by Danfoss hydraulic power unit, as well as custom discs, hubs, mounting brackets, bolts, and various types of control systems engineered by Danfoss.
