MODEL SELECTION
Is this spindle right for your machine?
Check before ordering
The spindle winding uses 220 V. The 24 V DC fan and sensor connections are separate auxiliary circuits; they are not alternative spindle supply voltages.
Compare alternatives
For a machine built around BT30 tooling and a water circuit, compare the GDL120-30-24Z/5.5. Changing the taper also changes the installation and tool-change requirements.

INSTALLATION CHECKS
Match the whole assembly.
Match the ISO20 toolholder, mounting pattern, side clearances and signal wiring. A similar power rating does not establish interchangeability.
- Confirm pneumatic requirements and the release/clamp sequence for your machine.
- Verify fan and sensor wiring separately from the spindle winding.
- Use the dimensional PDF for installation checks. Include the exact configuration in requests for additional drawings.

MODEL QUESTIONS
Before you order.
Is 24,000 rpm the rated speed?
No. The drawing lists 18,000 rpm at 300 Hz as the rated point and 24,000 rpm at 400 Hz as the maximum.
Can the spindle run from the 24 V auxiliary supply?
No. The 24 V DC connections serve the fan and sensors. The spindle winding is specified for 220 V.
