Lubrication and Bearings
Bearing grease will lose its lubrication ability over time,
not suddenly. The lubricating ability of a grease (over
time) depends primarily on the type of grease, the size of
the bearing, the speed at which the bearing operates and
the severity of the operating conditions. Good results
can be obtained if the following recommendations are
used in your maintenance program.
The recommended lubrication interval for 1800-RPM
motor, up to and including NEMA frame 215T is every
12000 hours of operation. It is important to remember
that this recommendation is base of average use. Refer
to Table 2 for additional information.
Types of Grease
A high-grade ball or roller bearing grease should be
used. See Table 3 for Recommended Greases.

Lubrication Procedure
Be sure that the grease you are adding to the motor is
compatible with the grease already in the motor. Consult
your factory representative if a grease other than the
recommended type is to be used.
To avoid damage to motor bearings,
grease must be kept free of dirt.
With Grease Outlet Plug
1. Clean grease tting.
2. Remove grease outlet plug.
3. If motor is stopped, add the recommended amount
of grease. If motor is to be greased while running,
a slightly greater quantity of grease will have to
be added. Add grease slowly until new grease ap-
pears at shaft whole in the endplate or purge outlet
plug.
4. Re-install grease outlet plug.
