Unbolt the grease collection chambers at the intervals shown on the notice plate with
the motor stopped, and remove the used bearing grease. If this is not done, the
grease will clog and the bearings will overheat.
WARNING
Rotor can fall out
If the machine is in a vertical position, the rotor can fall out while work is being
performed on the locating bearing. This can result in death, serious injury or material
damage.
Support or relieve the rotor when carrying out work with the machine in a vertical
position.
Grease types
For the standard operating range, a grease for temperatures down to -20 °C is normally used
for the initial greasing of rolling bearings. If the machine has been ordered for use in the
extended temperature range of below -20 °C, the permissible type of grease is indicated on
the lubricant plate.
Note
Grease quantity control
The grease quantity control only operates correctly if the specified greases are used. This is
specified on plates attached to the machine.
9.1.9.5 Cleaning
Cleaning the grease ducts and spent grease chambers
The spent grease collects outside each bearing in the spent grease chamber of the outer
bearing cap. When replacing bearings, remove the spent grease.
Note
Dismantle the bearing cartridges to replace the grease in the lubrication duct.
