The Series 20 steering
control unit continues
Eaton’s tradition of
innovative design and high
quality that began with the
first fluid linked power
steering system.
You can count on this
steering unit to provide the
same smooth, predictable
steering as the Char-Lynn
steering units that provide
dependable, trouble-free
steering on applications
around the world.
• Provides much
smoother steering
function by minimizing
jerky motion on
articulated vehicles.
• Jerk-reducing valves and
accumulators can be
eliminated on most
vehicles, providing
customer savings through
fewer components
required and reduced
system cost.
• Symmetrical valving
provides passageways
and valving that are
equally placed, and
pressure areas that are
staged for minimum
internal leakage. This
results in balance,
precise servo response
and uniform left or right
steering action.
• Eaton’s high capacity
gerotor provides ample
fluid displacement from
an even more compact
unit than was previously
offered.
• A thicker sleeve
design provides
stability, especially
during pressure and
thermal transient
conditions.
• The seal and centering
spring designs provide
positive, low-effort
steering feel to ensure
excellent vehicle control,
an important feature for
the vehicles for which
these steering control
units were designed.
