Hydrostatic bearing systems – wear-free, precise, with high running smoothness. 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 ...
Bearings that interest us are in 3 categories: Hydrodynamic, Hydrostatic, and Roller. Hydrodynamic and the hydrostatic make use of a phenomenon called the Wedge Effect. This wedge effect is a self-generated pressure that is developed when a film of oil between a moving shaft and a collar or sleeve is forced through a wedge shaped passage.
W. Brian Rowe, in Principles of Modern Grinding Technology, 2009. Hydrostatic Slide-Ways. Hydrostatic bearings tend to be reserved for machines that require the highest accuracy (Rowe 1974).Hydrostatic bearings have the advantage of very low friction at low speeds and allow a work table to be positioned with extremely high accuracy.
