Hydrostatic spindles - Precise, wear-free, with a high running smoothness The hydrostatic spindles from ZOLLERN impress with their very good concentricity and axial runout accuracy as well as the excellent damping, which makes it possible to achieve high surface qualities. The resulting heat is dissipated directly via the oil thanks to the constant oil circulation. This leads to a high thermal stability and consistently convincing technical properties. The constant separation of bearing surfaces by a thin film of oil guarantees freedom from wear and therefore a calculative unlimited service life. Features The ZOLLERN bearing clearance compensator works without susceptible capillaries or controllers Dimensions according to customer requirements Optional delivery of complete hydraulic system and control Optional: Composite casting bearing with special emergency running properties Advantages Calculative unlimited service life Concentricity and axial runout accuracy up to < 0.1 µm attainable Very good damping properties Thermally stable High level of running smoothness, no vibrations from rolling elements
