Ring oil lubricated: This system utilizes
slinger rings running in, or near the bearings
to pick oil up from the bearing housing oil
reservoir and deposit it on the shaft. The oil
then is transferred to the bearings by means
of channeling and/or catch-drip type
devices. If it is required, heat exchangers or
fans can be added to these type units to
maintain acceptable lube oil temperatures.
See Figures 4 & 5.
Units equipped with constant level oilers
are adjusted at the factory to the proper
level prior to shipment. However, the level
should be checked prior to operation. The oil
level mark is either cast into the housing, or
marked on an oil level tag which is attached
to the housing. If the tag is missing, refer to
factory supplied documentation. This oil
level dimension is from the shaft centerline
to the level of the oil in the bearing housing,
which also correlates to the top of the star
nuts. If it is necessary to adjust the star nuts,
loosen and adjust to the proper height, and
secure the bottom jam nut. Fill the bearing
housing reservoirs to the required oil level.
Fill oil bottle and position them on the star
nuts and secure with thumb screws.
Oil mist: With this type of lubrication system
the oil reservoir is separate from the pump.
The bearings are lubricated by an oil vapor
that is forced through the bearings. This type
of system will run cooler than most as there
is a small film of oil on the bearings
