Bearing temperatures may be up to 16 °C (30 °F)
higher than the housing temperature.

5.2.2
Grease
Do not fill the housing with oil when
greased bearings are used. The oil will leach the
grease out of the bearings and the life of the bearings
may be drastically reduced.
5.2.2.1
Grease for life
Double shielded or double sealed bearings
These bearings are packed with grease by the
bearing manufacturer and should not be relubricated.
The replacement interval for these bearings is greatly
affected by their operating temperature and speed.
Shielded bearings typically operate cooler.
5.2.3
Oil mist
The inlet port for all horizontal pumps is the plugged
½ in. NPT located at the top of the bearing housing.
A plugged ¼ in. NPT bottom drain is provided on the
bearing housing. See section 4.6.6.2, Piping
connection - Oil mist lubrication system. Do not allow
oil level to remain above the center of the bearing
housing sight glass window with purge mist (wet
sump) systems.
