Grease for
initial lubrication
The initial
amount of grease is determined by adjusting the full pack volume
for the operating speed and temperature. If the operating temperature
is above 180°F(80°C), the bearing should be packed with
25% of the full pack amount regardless of speed. For temperatures
below 180°F(80°C), the following chart should be used.
Speed in this
case is expressed as dn (shaft diameter x rpm). The proper initial
grease pack percentage for various dn ranges is shown below.
