GDK100-12-24Z/2.2-4.4
A water-cooled ER20 spindle with a 12,000–24,000 rpm operating range. Read the 2.2–4.4 code alongside the original power curve; the higher value is not a continuous-power promise.

Is this spindle right for your machine?
Check before ordering
The curve distinguishes S1 and S6-20% duty at TA20°C. It shows 269–380 V curve endpoints over 400–800 Hz; these are not separate winding choices.
Compare alternatives
For a fixed 24,000 rpm point and a smaller 80 mm body, compare GDZ-23. Confirm that its power, interface and installation suit the intended work.

Read the operating conditions.
The rated output is 2.2 kW. The drawing lists 6.8 A, 12 kg, a 100 mm body and 295 mm overall length. Additional power on the curve depends on the stated duty conditions.

Power curve: S1 and S6-20% at TA20°C are distinct duty conditions. The 2.2–4.4 model code and 269–380 V curve endpoints do not establish continuous 4.4 kW output or separate winding options.
INSTALLATION CHECKS
Match the whole assembly.
Compare the complete power-versus-speed curve, duty cycle, clamp dimensions and drive capability. Do not select the replacement from the 4.4 value in the code alone.
- The higher curve output is duty-dependent; do not use it as continuous rated power.
- Curve voltage endpoints do not establish selectable winding configurations. Also check the air-sealing connection shown in the drawing.
- Use the dimensional PDF and original power curve for installation checks.

MODEL QUESTIONS
Before you order.
Is this a 4.4 kW continuous spindle?
The rated output is 2.2 kW. The curve separates S1 and S6-20% conditions at TA20°C, so the higher output must retain its duty conditions.
Are 269 V and 380 V two winding options?
No. They are endpoints on the documented drive curve. Confirm the electrical configuration rather than treating each endpoint as an order option.
