PARAMAX 9000 Operation Manual
9.4 Maintenance of Motor Bearings
These maintenance instructions apply to Sumitomo motors.
The respective operating instructions apply if brake motors, servo motors, direct current motors or
vector motors or motors from other manufacturers are used.
Bearing types and maintenance methods differ depending on the sizes. For this please note the rating
plate and bearing type as in Tab. 24.
Type of bearing

Tab. 24
Maintaining Sealed Bearings
As sealed bearings are filled in advance with high quality lubricant, they do not have to be topped
up when commissioning. Under normal operating conditions we recommend replacing the bearings
during dismantling or maintenance every three - five years for continuous running or after 20,000
operating hours.
Using CM Class Bearings
Using "MULTEMP SRL (Kyodo Yushi)"
Under extreme operating conditions, replace bearings at shorter intervals.
With externally cooled motors where the service life of the fan motor bearing is 15,000 - 20,000 hours
we recommend replacing the fan every 15,000 hours.
Maintaining open Bearings
Re-lubrication intervals and amounts
Check the bearing number on the rating plate and top up the lubrication as shown in Table 25.
Tab. 25
Initial Amount: Top up amount after dismantling and cleaning the bearing. Pour about 1/3 of the
quantity directly into the bearing and the rest of it into the internal space.
Top Up Amount: The amount of grease that is poured into the bearing after each interval.
Even if the bearings are not to run continuously they must be re-lubricated at least every three years.
If the unit is not used for some time it must be lubricated again immediately After it is Started Up again.
