Alternate Lubrication Procedure:
Stop rotating equipment. Add one half the recommended amount shown in Table V. Start the bearing
and run for a few minutes. Stop the bearing and add the

second half of the recommended amount. A temperature rise after lubrication, sometimes 30°F (17°C), is
normal. Bearing should operate at temperatures less
than 200°F (94°C) and should not exceed 250° (121°C)
for intermittent operation. For lubrication guidelines,
see Table VI.
Note: Table VI are general recommendations. Experi-
ence and testing may be required for specic applica-

Expansion Bearing Applications:
Before installation, make certain proper expansion is
accounted for. Expansion units should be placed in a
location where relative movement between the bear-

applications using expansion type units, the xed unit
(non-expansion unit) is placed at the drive end of the
shaft. Use Table VIII to review the total available bearing
expansion. If the application requires additional expansion, consult Application Engineering.
NOTICE: One expansion unit is to be used in conjunc-
tion with one non-expansion unit for applications using
adapter lock units. Failure to utilize one expansion and
one non-expansion unit is likely to result in reduced
bearing performance.
