PRECAUTION
Damages to the motor bearings
If the motor shaft is knocked, the bearings may be damaged.
If belts are used for the transmission of the torque or a gear with radial load, make sure that the admissible radial
load is not exceeded on the motor shaft. The specific data for the admissible radial loads for each size of motor
can be found in the Table 17 description of the bearings given in previous sections.
PRECAUTION
Damages to the motor bearings
If the maximum value of the admissible radial load is exceeded, the shaft may break and the bearings may seize
up due to fatigue. The customer is responsible for making sure that the tension of the transmission belts does
not exceed the established limits.
