LUBRICATION INSTRUCTIONS
OPERATION IN PRESENCE OF DUST, WATER OR
CORROSION VAPORS
This bearing is factory lubricated with No. 2 consistency lithium
complex base grease which is suitable for most applications.
However, extra protection is necessary if bearing is subjected
to excessive moisture, dust, or corrosive vapor. In these cases,
bearing should contain as much grease as speed will permit (a
full bearing with consequent slight leakage through the seal is
the best protection against contaminant entry).
In extremely dirty environments, the bearing should be purged
daily to flush out contaminants. For added protection, it is
advisable to shroud the bearing from falling material.
HIGH SPEED OPERATION
At higher operation speeds, too much grease may cause
overheating. In these cases, the amount of lubrication can
only be determined by experience. If excess grease causes
overheating, remove grease fittings and run for ten minutes. This
will allow excess grease to escape. Then wipe off excess grease
and replace grease fittings.
In higher speed applications, a small amount of grease at
frequent intervals is preferable to a large amount at infrequent
intervals. However, the proper volume and interval of lubrication
can best be determined by experience.
AVERAGE OPERATIONS
The following table is a general guide for normal operating
conditions. However, some situations may require a change in
lubricating periods as dictated by experience. If the bearing is
exposed to unusual operating conditions, consult a reputable
grease manufacturer.

OPERATING TEMPERATURE
Abnormal bearing temperatures may indicate insufficient
lubrication. If the housing is too hot to touch for more than a few
seconds, check the temperature by applying a thermometer at
the top of the pillow block with the thermometer tip surrounded
by putty.

Because the thermometer reading will be approximately 10°F
lower than the actual bearing temperature, add ten degrees to the
reading and compare to the temperature rating of your grease.
If the bearing temperature reading is consistent and operating
within the recommended limits of your grease, the bearing is
operating satisfactorily. The recommended maximum operating
temperature for S-2000 Spherical Roller Bearings is 200 °F.
STORAGE OR SPECIAL SHUT DOWN
If equipment will be idle for some time, before shutting down, add
grease to the bearing until grease purges from the seals. This
will ensure protection of the bearing, particularly when exposed
to severe environmental conditions. After storage or idle period,
add fresh grease to the bearing before starting.
