NOTE: If coolant temperature can fluctuate below 70°F
during low ambient conditions, then an oil sump heater/
thermostat should be installed to ensure proper oil
temperature is maintained.
CAUTION: Do not stand on water pipes.
Remove and reinstall,using sealer, all pipe plugs not
previously removed.
Prior to placing the bearings into operation check for cooling
pipe leaks by placing the cooling water system into operation
at normal operating pressure and flow rate. If a leak is detected,
remove and reinstall the coolant pipes with pipe sealant, and
check again.
When using air as the cooling medium, connect an inlet to each
pipe on one side of the bearing and an outlet to the pipes on the
other side Adjust flow to rate specified on construction drawing
or to suit conditions.

LUBRICATION AND OPERATION
Since the satisfactory operation of the pillow block depends
almost entirely on the oil film being maintained between the
shaft and bearing liner surface, the use of a high quality oil from
a reputable manufacturer is recommended. Use a high grade
straight mineral oil with rust and oxidation (R & O) inhibitors and
anti-foam agents. Check construction drawings or equipment
instruction manual for proper oil. Oil viscosity is determined
by the equipment manufacturer and normally specified on
the construction drawing. Information regarding qualities and
properties of specific oils should be referred to the lubricant
manufacturer.
If bearings do not have circulating oil, fill pillow block with oil to
top of center circle in the oil gauge.
After placing into operation remove inspection covers and check
to make sure oil rings are bringing up oil. Operation should be
checked frequently during the first few days.
IMPORTANT: Check and re-torque plunger screw to the
specified torque after 24 hours or initial start-up and then
check periodically as required.

If noise develops, check alignment of housing, plunger screw
and all operating parts. Check all points and re-torque bolts
and plunger screws after several days operation. Maintain oil
level between top and midpoint of the oil level gauge at all times
while unit is in operation. Oil will leak out of the shaft seals if the
bearings are overfilled with oil.
NOTE: Bearings should NOT be stored outdoors before
installation. For extended or outdoor storage, contact
equipment manufacturer for special storage instructions.
NOTE: Bearings (and shafts) allowed to set idle for extended
periods after being run MUST be protected against
corrosion. If the unit can not be run for several minutes at
least once a week, consult equipment manufacturer for
special lubrication instructions.
