8.2.4. LUBRICATION INTERVALS FOR HIGH
TEMPERATURE
ATTENTION
Lubrication intervals and amount of
grease given in the tables below
should only be taken as advisory
information. For relubrication, follow
the intervals and grease amounts
indicated on the identification
nameplate.
Lubrication intervals for horizontal mounted ribbed
cooled and tube cooled motors (50Hz and 60Hz)
operating at an ambient temperature range -20ºC
up to +55ºC are present in the Table 8-9:
