MODEL SELECTION
Is this spindle right for your machine?
Check before ordering
The 258.5 mm overall length differs from the 2.2 kW base version. The same power rating or GDF46 family name does not mean the mounting dimensions match.
Compare alternatives
Compare the 2.2 kW base model if more rated output is needed; compare the housing-mount model only when the mounting arrangement can change.

- 220 V · 5.6 A
- 380 V · 3 A
INSTALLATION CHECKS
Match the whole assembly.
Start with the exact GDF46-18Z/1.5 configuration (base mount). Compare the mounting drawing, nose clearance and connection locations with the existing installation. Check the collet, nut clearance and usable clamp area before reusing tooling or supports.
- Allow unobstructed cooling airflow and confirm any fan wiring.
- Match the drive to the selected winding’s voltage and current.
