Universal Actuator™

Retrofit your pneumatic dual disc brake with DFE Universal Actuators and enjoy the benefits of quick-change friction pads and Silencer™ squeal-suppression technology.

We refer to our pneumatic brake actuator as ‘Universal’ because of its simple interchangeability between dual disc brakes of different sizes. The same actuator is used in varying quantities in our 90 to 1800 Series dual disc brakes. The Universal Actuator™ is also interchangeable with pneumatic cylinder assemblies on some dual disc brakes of other manufacturers. An example of a Universal Actuator™ retrofit we completed at International Paper is described in a case history here.

Advantages of the dual disc brake with Universal Actuator™ design include hassle-free friction pad removal and installation — no tools are required to change brake pads, a patented quick-change pad release lock, a limited travel actuator piston that prevents disc scoring, and a return spring that cannot puncture the actuator diaphragm.

Benefits of a Universal Actuator™ Assembly

• Proprietary ‘quick-change’ release locks allow friction pads to be changed out in seconds without tools. Because the machine operator can do this himself, downtime for pad changes by maintenance personnel is eliminated. Actuator bolts never need to be loosened to make pad changes.

• Zero-maintenance piston design. The piston diaphragms are sealed from contact with the actuator spring. This feature, in conjunction with DFE’s limited-travel piston, has eliminated the possibility of a blown diaphragm. The limited-travel pistons also prevent disc scoring.

• Replacing an existing actuator assembly with DFE’s user-friendly alternative is more efficient and less expensive than replacing an entire brake. Savings are substantial if upgrading multiple unwinds.

• All DFE products are warranted to be free of defects in material and workmanship for 5 years — the industry’s longest warranty.
