Temperatures up to 160
F (71
C) are considered
normal for bearings, and they can operate safely to
at least 180
F (82
C).
Checking bearing temperatures by hand is inaccu-
rate. Bearing temperatures can be measured ac-
curately by placing a contact-type thermometer
against the housing. Record this temperature for
future reference.
A sudden increase in bearing temperature is a
warning that the bearings are at the point of failing
to operate properly. Make certain that the bearing
lubricant is of the proper viscosity and at the cor-
rect level (see
LUBRICATION
in
MAINTENANCE
AND REPAIR
). Bearing overheating can also be
caused by shaft misalignment and/or excessive vi-
bration.
When pumps are first started, the bearings may
seem to run at temperatures above normal. Con-
tinued operation should bring the temperatures
down to normal levels.
