Rexroth IndraDyn A Application Notes
9-35
The bearing option for the coupling attachment (type code “R“) allows the
acceptance of higher circumferential radial forces, such as can result
from motor operation in connection with a coupling.
Advantages:
1. Couplings with a high rate of radial rigidity can be used.
2. High level of resistance to circumferential radial forces that can occur
during motor operation with a coupling.
Disadvantage:
A reduced maximum speed of the motor is available to it.
Tips for Selection
Determine bearing load
Observe
- radial force Fr, distance X
- axial force Fa
- mean speed nm
- period of use of motor
