•
Motors with a reinforced bearing may be operated only with a
permanent radial load (see Fig. 9-50). The bearings could be
damaged by resulting sliding friction
Motors with a reinforced bearing must be operated as a minimum with the
following radial loads.
Frame size
130
160
180
225
Minimum radial load
[kN]
1
1,5
2
Fig. 9-50:
Minimum radial load with reinforced bearing
The high-speed bearing (type code option "H") permits very high speeds
due to a deep-groove ball bearing with an accordingly low-weight
construction.
Advantage:
•
Very high speeds are possible
Disadvantage:
•
Can only be used with low radial load
•
Use in motor frame sizes 100…130 only
•
with horizontal motor installation position, and
•
without shaft sealing ring at the output shaft
Bearing for coupling connection (type code option “R”) allows for
absorption of higher rotating radial forces which can occur when the
motor is operated in connection with a coupling.
Advantages:
•
Couplings with higher radial stiffness can be used.
•
High resistance to rotating radial forces which may occur when the
motor is operated with coupling
Disadvantage:
•
The available maximum motor speed is reduced
