Installing A Bearing
The bearings have sufficient grease for at least 24 hours of operation after start-up. The bearings will run
hotter than normal for the first few hours until the grease is worked out of the ball path and the bearings
have “run in”. Adding more grease during this period may increase the bearing temperature.
After the first regreasing, a small amount of grease should be added at each fitting every 500 hours of
operation.
Normal Bearing Temperature
Long bearing life is quite dependent on careful handling of a bearing when it is out of the housing and
during the installation procedure. Dirt and rough handling are prime enemies of precision bearings. Bear-
ings should be pressed, not “hammered” into place. If heat is used to facilitate the installation, a hot oil
bath is the best method. Bearings for grease lubrication should be hand-packed with grease to ensure
adequate lubrication at start-up.
NOTICE:
The shaft seals above each bearing should be oiled with a few drops of #30 oil before the
pump is started to ensure lubrication of the seal lip.
