Oil Lubrication
(Adapter Mount or Direct Mount)
USN bearings are specifically designed to handle either grease
or oil lubrication. Oil lubrication is normally required at high
speeds as well as high loads or whenever heat from an external
source is flowing into the bearing. Oil lubrication may be static
or circulating. With static oil, fill the bearing cavity with oil up to
the centerline of the lower roller. The dimension is identified as
"w" and is shown on Table 12. Mount an oil sight gauge in the
drilled and tapped drain hole on the side of the plummer block
for visual indication of this level. The oil level may drop or rise
during operation depending on the rotation of the bearing. Oil
should be added only when the bearing is not operating. Both
the static oil level and the running oil level should be marked on
the oil sight gauge and properly identified.
Prior to installation on the structure, if the application RPM is
greater than 20% of catalog maximum speed, excess grease
must be removed to the levels outlined previously. Removal of
excess grease must be done in a clean, protected environment.
For circulating oil, the flow rate and size of return drains are
shown in Table 12. Consult application engineering for ABB
MPT products for recommendations.
