DMA2 & DM1 Mounting & Maintenance Instructions
Motors with sealed bearings and no re-lubrication system require no
maintenance other than checking for noise & temperature during their lifetime.
Sizes 280 up to and including 400, has been provided with a permanent lubrication system
containing a grease valve. The lubrication must take place when the machine is running.
The old grease is ejected from the grease valve thus maintaining the correct level and
avoiding overfilling which would be harmful.
7.5.
Replacement of ball or roller-bearings
When a bearing has to be replaced, the old bearing has to be removed from the shaft with
proper tools in order not to damage the shaft. Thereupon the bearing location on the shaft
has to be cleaned and checked thoroughly.
To fit a new bearing correctly, heat to 80 – 90 degrees centigrade with an electric
induction heater, then slip quickly onto the shaft up to the stop. In the case of a roller
bearing only fit the inner race in this manner.
A suitable sleeve may be used to help by tapping gently to seat the bearing home. Note
that under no circumstances must a bearing be driven home cold with excess force. We
must also stress that pressure must not be applied to the outer race of a ball bearing.
Do not mount the end shield until the bearing has cooled down.
