Water-cooled brakes

Absorbs and dissipates huge thermal loads

Select from four different models of Airflex water-cooled brakes designed to meet the needs of even the most severe applications. Our advanced design features match your specific application requirements, including high horsepower absorption, continuous slip service, thermal load dissipation, dynamic tensioning, static holding and emergency stopping.

• Better energy dissipation - Improved fluid dynamics
• Continuous slip service - Absorbs and dissipates huge thermal loads
• Several torque capacities - 1:1 dynamic-to-static torque ratio

Continuous slip service

All models are designed to absorb and dissipate heavy thermal loads to provide continuous slip service all day long.

Patented piston design

Single or dual piston provides a wider range of applied tension with greater control. Standard single piston elements can be retrofitted with a dual piston powerhead to provide increased control.

Unique friction couple

A specially formulated friction material, interfacing with a copper alloy surface, eliminates the stick-slip characteristic associated with ordinary frictional devices. The dynamic coefficient of friction is greater than the static coefficient of friction.

Optional corrosion protection

For marine environment applications, we can add protective coatings to minimize corrosion.
