Caliper brake maximises safety, durability, and serviceability in demanding applications

Danfoss Power Solutions announces 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, minimising 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.

The ACB-F3 features a clamping force of 20 to 120kN and a braking force of 16 to 96kN. Release oil pressure ranges from 40 to 190bar (580 to 2,756psi). 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.
