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 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. Heating temperature for open bearings is 110℃.
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.
