Shrink disk connection

For non-positively transfer of the torques stated in the catalog in case of hollow-shaft gear units with shrink disk connection, observe the following peripheral conditions in addition to the information on the respective dimension sheet when dimensioning 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.
