Electric Vibrator Lubrication Cont.
The lubrication frequency is every 2000 hours of operation unless specified otherwise in the
table. There is an exception - 3600 rpm electric vibrators operating continuously or for long
periods of time should be lubricated in ½ the time specified using ½ the grease volume
specified. For all other vibrators, follow the table except when the operating temperature
exceeds 90°C. If the operating temperature exceeds 90°C, reduce the lubrication frequency and
lubrication volume by 50% for every 10°C increment above 90°C. If the electric vibrator
operating temperature exceeds 100°C, contact Italvibras USA by phone at 815-872-1350. The
electric vibrator should never operate above 120°C.
When adding grease through the grease fitting, make sure to clean the fitting so as not to
introduce dirt into the bearing. Add the specified amount of grease. Experiment with your
grease gun to determine how many grams are introduced with each pump. Never over-grease
a bearing since this will damage the bearing and cause high operating temperature.
Always use the correct grease. Never mix greases. Use Kluber NBU 15 grease in all MVSI 36
electric vibrators. All other electric vibrators are lubricated with Kluber NBU 8EP grease. Kluber
grease may be purchased direct from Kluber Lubrication by calling 800-447-2238. Italvibras
USA also stocks the Kluber grease.
