Altra Industrial Motion
AquaMaKKs water cooled clutches and brakes
are designed to provide accurate torque control
for heavy-duty tensioning applications.
AquaMaKKs™ clutches and brakes are pneumatically or
hydraulically controlled and water cooled. They consist of a
series of alternating friction discs and water jackets. Torque is
transmitted by applying axial force from the pneumatic,
hydraulic, or spring set actuator. Copper wear plates are used for
excellent heat dissipation. Models are available in 19”, 25”, and
36” diameter sizes. Torque ranges from 66,500 in.lb. @ 80 PSI
to 1,611,000 in.lbs. @ 100 PSI.
A new 36" composite water
jacket (above, left) weighs
approx. 95 lbs. A comparable
36" cast iron jacket (above,
right) weighs approx. 375 lbs.
The reduced weight is a
signicant maintenance benet,
as well as when equipment is
installed in weight restricted
applications such as mobile
yarders in the forestry industry.
New engineered composite water jacket
improves performance
Wichita engineers have utilized the latest cutting edge technologies
and state-of-the-art materials to develop a revolutionary new
breakthrough in water cooled clutch and brake design...
composite water jackets (patent pending).
Corrosion resistant, saltwater friendly
Composite material will not corrode, so salt water and water sources
with high PH acidic values can be used for cooling without the need
to supply fresh water.
Other composite water jacket benefits include:
• Improved channeled water flow - achieved via groove
designed and molded into jacket providing enhanced
cooling capability
• Fast & easy maintenance created from the lightweight
composite jacket design that is about 25% the weight of the
competitors metal design
• Water jacket design and material allows for longer life,
requiring fewer replacements
• Reduced overall clutch weight – critical for weight
restricted applications (eg: truck mounted)
AquaMaKKs Water Cooled Clutches and Brakes
No optional salt water corrosion protection is required
Features
• Simplicity of design with fewer parts
simplifies installation and maintainability,
saving both time and money.
• The standard AquaMaKKs design
incorporates premium materials and
finishes suitable for marine deck
environments. No optional salt water
corrosion protection is required.
