110 Series Dual Disc Pneumatic Brake

Named for its 11" diameter discs, the 110 Series pneumatic brake provides steady tension control within a torque range of 19 to 6,210 lb-inches.

As an integral part of a high-performance unwind package, the 110 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 six. The term ‘110 Series’ is derived from ‘11’ – the brake diameter in inches, and our use of a third digit to signify the number of cylinders that are installed on the brake.

Aside from their heavy-duty, ductile iron disc construction and expanded surface for rapid heat dissipation, 110-Series brakes 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 ‘No-squeal Warranty’

To see if a brake in the 110 Series is the right size for your application please note its torque range listed below and review the 110 Series Brake section of DFE’s full Brake Catalog for detailed sizing information or contact an applications engineer for assistance.
