NOTICE
Damage to the bearing caused by excessive forces
Avoid axial forces when installing on the motor.
Note
Dimension z12 applies for standard assignment of the coupling. If a special assignment is
required, consult the appropriate special dimension drawing.
Note
Reduce assembling force
Lightly grease or oil the gear ring tooth flanks of the flexible element 1557 or the hub.
The following are permitted:
• Mineral-oil based oils or greases
• Silicon-based lubricants
• Vaseline
Note
The force required to join the coupling halves is released after mounting. Therefore, there is
no danger of excessive axial load on the bearings.
Note
The contact surfaces between adapter and motor must always be sealed using a suitable
sealing compound.
