MODEL SELECTION
Is this spindle right for your machine?
Check before ordering
The spindle uses ER20 tooling, but the original drawing gives conflicting nose-thread dimensions. Confirm the thread before ordering a matching nut or other threaded hardware.

INSTALLATION CHECKS
Match the whole assembly.
Start with the exact GDK100-24Z/3.2 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.
- Match the drive to the selected winding’s voltage and current.

MODEL QUESTIONS
Before you order.
What tooling and mounting does GDK100-24Z/3.2 need?
This configuration combines ER20 tooling, 24,000 rpm rated and Ø100 mm · 295 mm overall · 140 mm clamp. Keep the complete code when comparing drawings.
What should I include in a replacement inquiry?
Include the existing nameplate, mounting dimensions, required ER20 tooling, drive details and cooling arrangement. GDK100-12-24Z/2.2-4.4 has a documented speed range and duty-dependent curve; it is not the same output configuration.
