Lubrication
Vibrators up to the housing size 120 have
ball bearings. These are lubricated for their
service life (permanent lubrication).
Roller housings are mounted from housing
size 130 up. These are lubricated with the
grease of the type KLUEBER Staburags
NBU 8 EP. This grease has the advantage
that the bearings are lubricated for a period
of at least 5000 operating hours (up to
3000 rpm). After this time the grease of the
bearings has to be replaced completely.
Vibrators with speeds above 3000 rpm are
to be lubricated regularly every 1000 oper-
ating hours.
The lubrication intervals must be consider-
ably shortened under more difficult operat-
ing conditions.
Service life of ball and roller bearings
When operating in a potentially explosive
dust atmosphere, the operator must regu-
larly check the condition of the bearings
and the duration of operation of the vibra-
tors.
Vibrators with damaged bearings or with
bearings whose service life has been
reached, must be sent immediately to
NetterVibration for replacement.
