NOTE: Do not tighten plunger screw on accompanying
base loaded bearing until cap loaded bearing has been
installed and hold-down removed.
Base Loaded Bearings: Tighten plunger screw to
recommended torque given in Table 2 and tighten locknut.
IMPORTANT: Check and re-torque plunger screw to the
specified torque after 24 hours of initial start-up and
then check and re-torque periodically as required.
13. Install Grommet and grommet washer. Snug up grommet
nut, not tight. If unit is to be cooled, connect flexible hose
to water pipe in pillow block and to supply and drain lines.
Use care to prevent kinks or sharp bends in flexible hose.
A valve should be placed ahead of inlet and a sight drain
should be used at outlet, if possible. Adjust coolant flow to
suit conditions. Under average conditions very little coolant
is required.
CAUTION: The water pressure should never exceed 120
p.s.i.
14. The oil level gauge may be located any distance from the
pillow block by the use of a coupling and pipe of the desired
length. The extended pipe must be supported so that it
remains straight and perfectly level. Use a spirit level–do
not guess. Use pipe sealer on all connections.
15. Remove all pipe plugs and flush liner bore and housing
thoroughly with solvent or cleaner. Reinstall pipe plugs using
pipe sealer. Tighten securely.
16. Each housing base has predrilled holes for doweling bearing
to base plate.
LUBRICATION and OPERATION
Since the satisfactory operation of the pillow block depends
almost entirely on the oil film being maintained between the shaft
and liner bearing surface, it is recommended that a high grade
straight mineral oil with rust and oxidation (R & O) inhibitors and
anti-foam agents be used. Check equipment specifications
for specific recommendations of oil viscosity by equipment
manufacturer. Oil viscosity is determined by the equipment
manufacturer and normally specified on the construction
drawing.

Fill the pillow block with oil to the top of the 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. After
some running of base loaded bearings only, loosen plunger
screw 1/4 turn, then retighten as specified. This will allow the
liner to align with the shaft. For cap loaded bearings, follow
installation procedure. If noise develops, check alignment of
housing, plunger screw and all operating parts. Check all points
and make sure all screws and nuts are tightened after several
days operation. Maintain oil level above bottom of center
circle at all times while unit is in operation.

Oil Maintenance Schedule
Drain, flush, and refill with oil after 2 to 3 weeks of initial break-
in operation. Since the satisfactory operation of the bearing
depends entirely on an oil film being maintained between the
shaft and the bearing liner surface, it is recommended that an oil
analysis be performed at these regular intervals.
•
Every 3 months for 24 hour/day service
•
Every 6 months for 8 hour/day service
Acceptability of oil should be referred to the lubricant manufacturer.
If oil quality is acceptable then repeat this procedure in three
month intervals. Visually check oil for contamination between oil
analysis checks. Oil service life depends upon several factors
such as ambient conditions, operating temperature and frequency
of bearing starts and stops. It is recommended that the oil be
changed at least once per year for unfiltered static applications.
Removing contaminants through the use of either the OLF-2 (Oil
Level and Filtration) unit, Cool Lube 2, or a circulating oil system
can extend oil service life. Consult equipment manufacturer for
more information.
NOTE: The MINIMUM oil temperature at start-up is 70ºF.
Oil film temperature in liner during operation should not exceed
180ºF. If in doubt, consult equipment manufacturer.
Any question on installation, maintenance, or arrangement
of coolant connection inlets and outlets should be referred
to the original equipment manufacturer.
