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.
