5.2 Maintenance
The service life of the bearings and sealing elements can differ greatly depending on the operating
conditions, (e.g. operating mode, temperature, speed and load).
In the case of trouble-free operation, we generally recommend the following maintenance
procedures:
• Replacement of the bearings after 20,000 running hours (the bearings are designed for a
calculated service life of 20,000 running hours)
• Replacement of the shaft-sealing ring after approximately 5,000 running hours, if present and
if no leaks have been detected during previous inspections
• Re-lubrication DA 280.W:

High temperature greases only are recommended for initial lubrication and re-lubrication, e.g.
Asonic HQ 72-102 / FAG L 237.
If an optional brake is fitted, it is essential that it is replaced when its wear limits are reached.
The maintenance work is to be undertaken by Baumüller or a specialist organization authorized by
Baumüller.
Caution!
The specifications of the technical instructions TAM 00697 must be followed during
maintenance and servicing on motors which are used for safety-oriented applications.
6 Disposal
The motor must be disposed of in accordance with the relevant national and local regulations
within the framework of the normal recycling process.
The encoder electronics (if provided) must be disposed of in the proper manner as electronic
scrap.
