4.3.5 Checking and replacing the roller bearing and the spindle assembly
4.3.5.1 Checking and replacing the roller bearing with seat in the bearing block
In the spindle axes ELGA-BS-KF-70 /80 / 120 / 150, the bearing of the spindle module in the bearing block differs
depending on the size:
– ELGA-BS-KF-70 with two
deep-groove ball bearings
,
– ELGA-BS-KF-80 / 120 / 150 with two angular ball bearings .
The rolling behaviour of the roller bearing in the bearing block and the roller bearing on the spindle assembly must
be checked with each repair. If the rolling behaviour of one of the two roller bearings is no longer perfect, e.g. due to
increased scratching noises, both roller bearings must always be replaced.
1. Check the rolling behaviour of the roller bearing in the bearing block and
the roller bearing on the spindle assembly.

1. Drive the roller bearing out of the bearing block.

Ensure that the seat of the roller bearing is not damaged when it is pulled off
the spindle assembly.
