Mounting
Transmission elements
• Fit or remove transmission elements only using suitable equipment.
• For fitting the transmission elements use the center hole in the shaft.
• Avoid impacts and shocks.
• In case of a belt drive, tension the belt in a controlled manner according to manufacturer information.
• Be sure to carry out mounting in a manner free from distortion.
• Compensate minor inaccuracies by suitable flexible couplings.
Fastening
• Use screws with a minimum property class of 8.8.
• Observe prescribed tightening torques.
• Secure against unintended loosening.
• For alternating loads, we recommend applying anaerobic curing adhesive between flange and mounting
surface.
Gearbox with hollow shaft and shrink disc
NOTICE
▶ Never disassemble the new shrink disc.
▶ Thoroughly clean and degrease hollow shaft bore and machine shaft!
▶ Do not tighten clamping screws before the machine shaft has been inserted, the hollow shaft may
undergo plastic deformation.
▶ Cover the shrink disc during operation so that it is secured against contact by implementing suitable
measures (e.g. cover).

1. Check machine shaft
- Diameter in fit tolerance h6
- Material yield point Re ≥ 360 MPa
- E-module approx. 210000 MPa
- Surface roughness R
- Concentricity (to prevent unnecessary additional forces caused by tensioning)
2. Thoroughly clean and degrease the contact surfaces of the hollow shaft bore and machine shaft.
3. Slightly loosen clamping screws (2) one after the other, do not unscrew.
4. Push gearbox onto machine shaft.
5. Slightly tighten clamping screws manually.
6. Tighten clamping screws (2) one after the other (approx. 5) in several passes, with rising torque, evenly
until the indicated screw‐tightening torque is reached at all screws.
