Assembly Instruction

Assembly Instruction

Do not exert any forces onto the housing or into the bearings during assembly. Use of the threaded holes d7 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.
