Best fit
For a ER20 installation with air-cooled and 24,000 rpm rated. Mounting requirements: Ø80 mm · 269.5 mm overall · 125 mm clamp. Compare these dimensions with the machine before choosing.

GDF SPINDLE · MANUAL
The ER20 version in this 80 mm air-cooled group is rated at 2.2 kW and 24,000 rpm. Keep its B designation when discussing the order.
QUICK DECISION
For a ER20 installation with air-cooled and 24,000 rpm rated. Mounting requirements: Ø80 mm · 269.5 mm overall · 125 mm clamp. Compare these dimensions with the machine before choosing.
Check the 125 mm clamping length and 269.5 mm overall length. These dimensions differ from the ER16 configuration.
Compare GDF80-24Z/2.2 for ER16 tooling; compare GDZ-23 when the machine uses water cooling.
