10.3 Replacing rolling bearings
Rolling bearings
When ordering rolling bearings, in addition to the bearing identification code, the
supplementary specifying code is also necessary for the bearing version. Both of these codes are
stamped on the lubricant plate and specified in the motor documentation, or can also be taken
from the installed bearings.
Always replace the rolling bearings with the identical bearings.
10.4 Rolling bearings
If insulated rolling bearings are fitted, use insulated rolling bearings of the same type as spare
parts. This will prevent any bearing damage being caused by bearing currents.
10.5 Groups of parts
A distinction is made between the following groups of parts:
Spare parts
Spare parts are machine parts that can be ordered during the production time - and for a
further 5 years after discontinuation of production. These parts should be replaced only by
authorized service or modification partners.
Repair parts
Repair parts are machine parts that can only be supplied during the active production of
the machine (until the product discontinuation). Repair parts are parts used for the repair
or modification of the current products. These parts should be replaced only by authorized
service or modification partners.
Standardized parts
Standardized parts are machine parts that can be commercially obtained with the
necessary dimensions, materials and surface finish. A detailed list can be found in Chapter
"Standardized parts".
Other parts
Other parts are small parts required to complete the exploded drawing. These parts cannot
be supplied as individual spare or repair parts. Delivery as assembled units, for example as
complete terminal box, is possible on request.
