Machine requirements
For machines that use ER20 tooling and water cooling. Check that your drive supports 24,000 rpm rated and that the mounting dimensions fit: Ø80 mm · 284 mm overall · 135 mm clamp.

GDK SPINDLE · MANUAL
An 80 mm water-cooled ER20 spindle at 2.2 kW and 24,000 rpm. The drawing provides a 135 mm clamping length for mounting checks.
MODEL SELECTION
For machines that use ER20 tooling and water cooling. Check that your drive supports 24,000 rpm rated and that the mounting dimensions fit: Ø80 mm · 284 mm overall · 135 mm clamp.
Allow for the 284 mm overall length and check the 0.1–0.2 MPa air-seal connection as well as the water circuit.
GDZ-23 uses the same nominal body diameter and ER20 interface but has a shorter documented assembly.
