1800 Series Dual Disc Pneumatic Brake

Named for its 18" diameter discs, the 1800 Series pneumatic brake provides steady tension control within a torque range of 33 to 17,990 lb-inches.

As an integral part of a high-performance unwind package, the 1800 Series Brake delivers the appropriate torque level needed for a particular application by allocating actuation of the appropriate number of cylinders, from one up to ten. The term ‘1800 Series’ is derived from ‘18’ – the brake diameter in inches, and our use of a third and forth digit to signify the number of cylinders that are installed on the brake.

Featuring heavy-duty, cast iron disc construction and expanded cooling surfaces for rapid heat dissipation, 1800-Series brakes also feature DFE’s time-proven Universal Actuator™ technology:

• Hassle-free changeout of worn pads, without tools, via push-button spring locks
• Limited-travel pistons that can’t scratch the disc
• Cylinder return springs that cannot puncture the diaphragm
• Able to be retrofit into dual disc brakes of other manufacturers
• DFE’s popular anti-squeal Silencer™ pad technology

To see if a brake in the 1800 Series is the right size for your application please note its torque range listed below and review the 1800 Series Brake section of DFE’s full Brake Catalog for detailed sizing information or contact an applications engineer for assistance.
