QUICK DECISION
Where this configuration fits.
Check before ordering
The drawing gives 125 mm clamping length and 284 mm overall length. An 80 mm clamp is not the specified body match.
Consider another model
Compare GDK80-24Z/2.2 if the machine uses an 80 mm clamp; confirm all other dimensions rather than adapting by name alone.

INSTALLATION CHECKS
Match the whole assembly.
Start with the exact GDK85-24Z/2.2D configuration. 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.
- Check the water circuit and the connector details shown in the drawing.
- Select the documented winding and keep its voltage and current together.
