5.2.4 Bearing operating temperatures
The maximum operating temperatures for anti-friction
bearings will differ from unit to unit. In general,
bearing frames using Timken bearings can run 40
o
C
(100
o
F) higher above ambient. This should be no
cause for alarm. However, continuously rising
temperatures, or an abrupt temperature rise, is
indicative of possible trouble. These symptoms
require immediate stopping of the pump and a
thorough investigation to determine the cause of the
trouble.

5.2.5 Selection of grease lubricants
The bearings are to be lubricated with a premium
quality lithium based NGLI # 2 grease suitable for
antifriction bearing use. The grease should have a
viscosity range of 150 to 220 cSt (mm
2
/sec) at 40
o
C
(100
o
F) and Timken load rating of 16 kg (35 lb.)
minimum. The grease should contain rust and
oxidation inhibitors and extreme pressure additives
Others greases meeting the above requirements may
also be used.
