ZOLLERN offers hydrostatically mounted spindles, rotary tables, guides and bearing components for applications where freedom from wear, a high level of precision and running smoothness are required.
For hydrostatic bearings, moving parts and housing are separated from each other by an oil film, independent of the load or sliding speed. There is no direct contact. Sliding bodies or the like are not used.
With the patented running clearance throttle, ZOLLERN has developed a unique and variable restrictor system, which is directly integrated into the hydrostatic bearing. External regulators, capillaries, hydraulic orifices or multiple pump circuits, as required by other hydrostatic bearing systems, are not required. In addition, there is no need to adjust the throttle system during commissioning. The optimal pocket pressure is therefore always set, regardless of the production tolerances.
The ZOLLERN clearance compensator ensures optimum pocket pressure in the spindle unit. It is integrated into the fully hydrostatic bearing part of the spindle and the optimum pocket pressure is automatically set within the manufacturing tolerances. The patented clearance compensator is a self-regulating system with fast control behaviour and high rigidity. It is used in spindles as well as in hydrostatic rotary tables and linear guides.
