SimsiteŽ Guide Bearings Lead the Way...
 Simsite's
Unique Qualities Work for You:
Machines are not always perfect. And when a lubricating system
fails, damage to a rotating element can be extensive. Simsite
Bearings' self-lubricating characteristics prevent
catastrophic failure. Simsite Bearings are significantly
superior to other guide bearings because they offer rigidity
to the rotating element as well as an unusually low
coefficient of friction. The superior lubricating values of
graphite are imbedded throughout the Simsite Composite.
Simsite
Bearings can take the heat...
Simsite Bearings can withstand extremely high flash
temperatures up to 1000 degrees Farenheit and continuous
running temperatures from 300 degrees Farenheit with standard
Simsite and up to 400 degrees Farenheit with a
high-temperature grade of Simsite.Unlike plastic, elastomer,
or rubber bearings, Simsite Bearings will not melt, get spongy
or soft, or seize when exposed to high temperatures. Most
bearing materials will not tolerate flash temperatures and
will literally melt on the shaft in the event of any dry
running.
Simsite
Bearings have a remarkably low coefficient of friction...
Simsite Bearings have an extremely low coefficient of
friction, because they have graphite embedded throughout the
composite which acts as a lubricant.When lubricated by water,
oil or grease, Simsite is ideal as a guide bearing, rudder,
stern tube, stabilizing or oil-seal bearing.
The
Strength of Simsite Protects your Equipment...
The unusually high mechanical strength if Simsite offers many
advantages over conventional bearings. They are precision
machined from a solid block of Simsite rather than poured or
molded. Because its fibers are never chopped, cut or
ground,the Simsite Bearings has greater shear, bound, flexural
and tensile strength than other materials. Simsite's
outstanding mechanical properties enable the bearing to
withstand higher loads and torque requirement. Unlike bearings
of carbon or pressed graphite, the Simsite Bearing will not
crack or break under load. Compare Simsite's superior tensile
strength with other bearing materials shown in the
chart below:
Electrolysis
is Substantially Reduced with Simsite
Because Simsite is basically an inert composite, electrolysis
is greatly reduced. Simsite Bearings seal against the casing
or the housing preventing leakage and eliminating the damage
of corrosion and erosion. This is critical because it insures
that the bearings will be secured properly reducing the risk
of damage to the entire rotating element.
Longer
Life for the Complete Rotating Element...
Because Simsite Bearings hold the shaft more securely than
conventional bearings, radial movement in the shaft is
reduced. This increase the life span of the entire rotating
element. When you combine a Simsite Impeller and casing rings
with a Simsite Guide Bearing the length-to-diameter (L/D) of
the rotating element is reduced. The stability of the rotating
element is therefore improved because of the lower mass. This
lower mass (approximately 1/5 the weight of bronze) accounts
for its excellent PV characteristics as is illustrated by the
chart below:
