MODEL HBA BRAKE DESCRIPTION
The Model HBA brake is an oil immersed, air or hydraulically
set brake designed to be mounted on a drive train shaft
extension. In the majority of installations, the Model HBA
brake utilizes the system’s lubricating oil for cooling.
Cooling oil is fed into the brake at the cylinder end of the unit
where it is directed into the oil distribution holes incorporated

MODEL HBS BRAKE DESCRIPTION
The Model HBS brake is identical to the Model HBA brake
except the unit is designed to be spring-set and hydraulically
or pneumatically released. This spring-set actuation feature
makes it suitable for those applications requiring the
presence of full braking torque in the event of loss of
actuation pressure or machine power.

within the rotating hub for dispersal through-out the disc pack.
Unique friction plate grooving patterns, as well as the forced
oil cooling feature, allow the Model HBA brake to dissipate
the heat generated by stopping the high energy loads
common to today’s heavy duty industrial equipment.
All torque transmitting members are designed to withstand
the rigors of the loads imposed. The unit incorporates high
quality, time proven materials selected to provide strength,
durability, and reliable performance.
The Model HBA housing contains the stationary plates of the
disc pack. This housing is bolted to the stationary machine
member and provides the grounding path for stopping the
rotating components of the drive train when the disc pack is
engaged. The housing also serves as a containment for the
cooling oil and provides a path for the oil to return to the
machine reservoir.
USAGES
Any type of industrial equipment that requires braking of
high speed-high energy loads with maximum reliability
and longevity.
Those applications that must operate in adverse
environments due to the Model HBA and HBS brake’s
totally enclosed features.
Tensioning control systems.
Propeller shaft brakes, winch holding brakes, mining safety
brakes (Model HBS), conveyors, lumber and paper making
equipment are some examples of where these brakes can
be applied. They are particularly suited to mounting directly
to gear cases. This allows sharing of the lubrication and
cooling system as well as provides system compactness
and a professional design appearance.
