Safety Information and Precautions
Oil Mist Lubrication I-M Manual
Oil Installation and
Maintenance
Installation
The motor bearings will receive a light coat of oil for
testing at the factory and for subsequent shipping.
Upon receipt of the motor, the oil-mist system must
be connected.
For motors labeled Provisions Only for Oil Mist
Lubrication or Oil Mist Ready, purge all oil and/or
grease from the bearings.
Remove the oil inlet and oil outlet pipe plugs from
the bearing brackets, caps, or remove the extension
tubes from the drive end and non-drive ends of the
motor.
Install the specified reclassifier to the top
connection.
Connect the oil recovery trap to the bottom opening.
Oil Supply
The lubricating oil should be rust- and oxidation-
inhibited, stray-mist suppressed, and manufactured in
accordance with established commercial standards
and practices.
The viscosity shall be ISO VG 68 or higher, per the
latest revision of ASTM D 2422.
The flash point shall be 350° F (177° C) or above.
The pour point shall be -15° F (-26° C) or above.
See Table 1 on page 3 for oil recommendations.
The oil type and misting unit must be compatible.
Storage
Motors that are labeled Provisions Only for Oil Mist
Lubrication have bearings that are packed with
grease. The storage procedures are the same as
those for motors with grease-lubricated anti-friction
bearings.
Motors that are labeled Oil Mist Ready have
bearings that are protected for temporary storage
by a corrosion inhibitor. ff extended storage (greater
then 3 months) or if stored outdoors, the units
should be connected to the oil mist system while in
storage.
If this is not possible, at three-month intervals, the
grease level should be checked and refilled as
required.
At each three-month check the shaft should be
rotated by hand five revolutions minimum to re-
distribute the bearing grease.
The bearing grease must be removed at the time of
connection to the oil mist system.
