Direct-coupled and 1:5 taper drive
Hydrostatic Spindles with External Motor
The same hydrostatic bearing technology, driven by an external motor through a direct coupling or a 1:5 taper. Keeping the motor outside the spindle body isolates its heat from the bearings, which suits continuous duty. Ten models from 5 to 30 kW. Requires a hydraulic power unit.
