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

(100

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

/sec) at 40

(100

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.
