Assembly Instructions

Do not exert any forces onto the housing or into the bearings during assembly. Use of the threaded holes d6 in the shaft is recommended.

The use of a corresponding coupling is recommended to compensate for manufacturing-related shaft offsets and runout tolerances as well as for damping vibrations and shocks.
