Lubricating
vibrator
Martin Engineering M3910-04/19
Read entire section before beginning work. Allow vibrator to
cool to ambient temperature before working on it.
All vibrators are lubricated at the factory.
Use only prescribed grease in vibrator. If a different grease is
used, vibrator can be damaged and warranty will be void.
Use only prescribed amount of grease to lubricate vibrator.
Too much grease will cause bearings to overheat and result in
premature bearing failure.
1. See Table V for lubrication schedule and amount of grease required for
your vibrator.
For 3600 rpm machines operating continuously or for long
periods of time, reduce lubrication time and amount as shown
in step 2. Failure to do so could run bearings dry and destroy
unit.
2. If motor housing temperatures exceed 194°F (90°C), cut lubrication time
and amount in half for every 18°F (10°C) increment that meets or exceeds
194°F (90°C). For example, if MM9-1440 motor housing temperature is
204°F (96°C), use 4.5 grams of grease per bearing every 1000 hours.
(Maximum bearing temperature allowed is 248°F [120°C].) For motor
housing temperatures above 212°F (100°C), consult Martin Engineering
or a representative.
Kluber grease may be purchased from Martin Engineering by
calling 800-544-2947.
3. For MM9, MM12, and MM18 model vibrators, lubricate frame size 35
and larger vibrators with Kluber Staburags NBU 8EP grease only.
For MM36 and MB36 model vibrators, lubricate frame size 35 and
larger vibrators with Isoflex NBU 15 grease only. Lubricate as follows:
a. Clean vibrator case around grease fitting.
b. Insert grease gun onto grease fitting. Add grease.
