Spring-Engaged Brake

Nexen introduced its dual faced brakes (DFB) and quad faced brakes (QFB) with torque capacities that range from 9,000 to 164,800 inch-pounds. The brakes feature a piston and cylinder actuator sealed with O-rings, as well as non-asbestos friction facings and low-inertia friction discs. The dual-faced brakes are engineered with a single-disc assembly, and the quad-faced brakes have a double-disc assembly. The brake housing is flange mounted to machinery, and the hub is keyed to the shaft. Cylinder inlet ports provide direct air supply.
