Shrink disk connection

To non-positively transfer the torques specified in the catalog in hollow-shaft gear units with a shrink-disk connection, observe the following boundary conditions in addition to the information given in the respective dimension sheet when designing the customer shaft:

• Surface roughness R_z ≤ 16 µm
• Elastic limit of the customer shaft material R_e and/or Rp_0.2 ≥ 305 N/mm²
• Design of the customer shaft as solid shaft

If the customer shaft is designed as a hollow shaft, contact SEW‑EURODRIVE.
