Mounted bearings are pre-lubricated at our factory and are
ready for operation.
LubRIcATIoN
Lubrication of bearings is determined by operating conditions
and environment. Lubricate standard bearings with a LIThIuM
based grease. Greasing intervals are shown on the next page
using the following symbol:
Frequency (50 hours)
gREAsINg INTERvALs
Bearings in extreme environments will require more frequent
greasing intervals.
gREAsE fILL AMouNTs
It is preferred that experience dictate fill amounts due to wide
variances in applications, greasing equipment and operat-
ing conditions. In most cases, it is best to lubricate in small
amounts, under low pressure, until a thin bead of fresh grease
is visible at the seal lip area.
5.10 gREAsINg
Care should be taken when greasing bearings to avoid overfill-
ing. Overfilling can lead to excessive heat and/or unseating of
the seals Grease should be introduced in small amounts and
under light pressure. Whenever possible, the bearing should be
rotated slowly while grease is added to ensure equal distribution
throughout the raceways.
The chipper models described in this manual have several
bearings that require greasing. Refer to the figures on the next
page for greasing locations and intervals.
The use of pneumatic grease equipment is not recommend-
ed unless low pressure is assured.
WARNINg
Polyuria and lithium based greases are not compatible. Mix-
ing the two grease types may lead to premature failure of
the chipper.
