How It Works<br />
A temperature switch is embedded in a DODGE Pillow<br />
Block. The switch is custom designed for the<br />
DODGE bearing. When the temperature of the bearing<br />
exceeds a predetermined value, the switch<br />
closes an alarm circuit. The optional alarm monitor<br />
consists of a warning light and high pitched buzzer<br />
which draws attention to the overheated condition.<br />
The monitor can be positioned based on the users<br />
specification.<br />

How It Works<br />
When powered by a DC power supply of 18 to 28<br />
volts, the accelerometer generates a signal between<br />
+5 and –5 volts which is representative of the vibration<br />
seen by the sensor. This signal then can be analyzed<br />
for any change in the amplitude of the various<br />
frequencies to assist in the identification of potential<br />
problems. The accelerometer is mounted on the inside<br />
of a protective cast enclosure.<br />

SPECIFICATION<br />
INCH<br />
DODGE Unitized Spherical Bearings, including S-2000,<br />
SN-2000 and <strong>UNISPHERE</strong> <strong>II</strong> bearings, are general purpose<br />
high capacity double row spherical roller bearings.<br />
All are mounted in single piece precision machined housings.<br />
Bearings are mounted to shafts by means of set<br />
screw collars, with 65 degree set screw spacing for maximum<br />
clamping force. Dodge Imperial bearings are<br />
mounted by use of tapered adapter sleeves.<br />
ASTM A48 Class 30 cast iron is the standard material<br />
used in S-2000 housings, Imperial flange housings and<br />
<strong>UNISPHERE</strong> <strong>II</strong> flanged housings. The standard material<br />
used in <strong>UNISPHERE</strong> <strong>II</strong>, Imperial and SN-2000 pillow<br />
blocks is ductile iron (ASTM A536 Grade 65-45-12) with<br />
65,000 p.s.i. tensile strength. Housing designs are available<br />
for survival in extreme harsh environments,<br />
through the use of special finishes and stainless hardware.<br />
Housings are available in a variety of standard configurations,<br />
including pillow blocks, flanges, piloted flanges and<br />
take-up bearings. Rubbing lip seals are standard on all<br />
units. Metal labyrinth seals are available as an option on<br />
S-2000 and SN-2000 bearings.<br />
