1800 Series Dual Disk Pneumatic Brake

The 1800 Series Dual Disk Brake, named for its eighteen-inch diameter disks, offers high performance in a torque range from 33 lb-inches up to 17,990 lb-inches.

As an integral part of a high-performance unwind package, the 1800 series brake allows you to deliver the appropriate torque level needed for a particular application by allocating actuation of the right number of cylinders, from one up to ten. The term 1800 ‘Series’ is derived from ‘18’ inches plus our use of the third and fourth digits in the range of values from 1801 to 1810 to signify the number of friction pads selected for a brake.

Aside from their heavy-duty, ductile iron disk construction and expanded surface for rapid heat dissipation, 1800 Series brakes feature DFE’s time-proven Universal Actuator technology:

  • Hassle free change out of worn pads, without tools, via push-button spring locks
  • Limited-travel pistons that can’t scratch the disk
  • Cylinder return springs that cannot puncture the diaphragm
  • Able to be retrofit into dual disk brakes of other manufacturers
  • DFE’s popular ‘No-squeal Warranty’


  • Disk/Hub Inertia 178.9 Slug-in2
  • Max. Torque 17,990 in-lbs
  • Disk/Hub Weight 172.8 lbs.
  • Max. Ship Wt. 236 lbs.
  • Min. Shaft Length 9.2 in.

To see if a brake in the 1800 Series is the right size for your application please note its torque range listed above and review the 1800 Series Brake section of DFE’s full Brake Catalog for detailed sizing information, options and accessories.
