Maintenance
7.1 Maintenance
Note
The shaft should rotate so that the new grease can be distributed throughout the bearing.
The bearing temperature rises sharply at first, then drops to the normal value again after the
excess grease has been displaced out of the bearing.

7.1.6
Cleaning
Cleaning the greasing channels and used grease chambers
The used grease collects outside each bearing in the used grease chamber of the outer
bearing cap. Remove the used grease when you replace a bearing.
NOTICE
You have to separate the active parts of the bearings to replace the grease that is in the
greasing channel.
Cleaning the cooling air passages
Regularly clean the cooling air passages through which the ambient air flows (e.g. using dry
compressed air).
NOTICE
The frequency of the cleaning intervals depends on the local degree of pollution.
Particularly when cleaning using compressed air, make sure you use suitable extraction
equipment and wear protective gear (safety goggles, respiratory filter, etc.).
