Product Features
The Model CBH combination clutch-brakes are oil immersed units with aspring-set brake and hydraulically-set clutch. They are designed for extremely
high cyclic rates and for those applications that require a high degree of
stopping accuracy.
Hydraulic actuation and precise control of piston stroke contributes to an
extremely fast response time. Actuation volumes are very small and the fluid's
virtually incompressible characteristics means that piston motion times can be
as low as 5-10 milliseconds. This, in turn, allows for more shaft motion time
since the units' hydraulic response time is so short. Cyclic rates in excess of
300 cpm are not uncommon in some applications.
Such high cyclic rates induce a large amount of shock into the mechanical
components of the unit and all members are designed to withstand these loads.
Oil films help dampen these shock loads and the units run extremely quiet. Noise
reductions of 25-30 dBA are common when compared to dry units running at the
same speeds and loads.
Wear characteristics of the Model CBH units are excellent. As an example, a Model
CBH unit was endurance tested for 120 million cycles with no appreciable lining or
mechanical wear. A dry unit was tested at the same load level and found to require
re-line every 10 million cycles and complete unit replacement every 30 million
cycles. There are many industrial applications which require longevities of this
magnitude and the Model CBH has exhibited outstanding performance in these instances.
