Turn the shafts at least once a year to avoid permanent standstill marks. If the bearings are stored for a
longer period of time, the grease service life of the bearings will be reduced (ageing). It is advisable to check
the condition of the grease on open bearings once a year. If there is any sign of de-oiling or contamination of
the grease, the grease must be replaced. Closed bearings (ZZ 2RS) must be replaced > 48 months after a
storage period.
11. Spare parts
With the exception of standard, commercially available and equivalent parts (e.g. roller bearings),
only original spare parts (see spare parts list) may be used; this applies in particular to seals and
connecting parts.
The following information is required when ordering spare parts:
Spare part designation
Motor type
Motor number
12. Disposal
The applicable national regulations must be observed when disposing of the machines. Electric motors are
regarded as components and therefore do not fall under the German Waste Electrical and Electronic Equip-
ment Act or the WEEE2 Directive.
Please also note that oils and greases are disposed of in accordance with the Waste Oil Ordinance. They
must not be contaminated with solvents, cold cleaners and paint residues.
The individual materials should be separated before recycling. The most important components are grey cast
iron (enclosure), steel (shaft, stator and rotor plates, small parts), aluminium (rotor), copper (windings) and
plastics (insulation materials such as polyamide, polypropylene, etc.). Electronic components such as circuit
boards (inverters, encoders, etc.) are processed separately.
