The hydrostatic rotary tables from ZOLLERN impress with their durability and a high concentricity and axial runout accuracy. Thanks to the ZOLLERN bearing clearance compensator, the optimal pocket pressure is set automatically and independently of production tolerances. The freedom from friction at low speeds prevents slip stick and therefore allows maximum positioning accuracy. Features Hydrostatic radial-axial bearing The ZOLLERN bearing clearance compensator works without susceptible capillaries or controllers Delivery with complete hydraulic system and control system optional Axial-composite casting bearing with special emergency running properties Advantages Calculative unlimited service life No ball reversal jump due to rolling element deflections when the direction of rotation is reversed Friction-free at low speeds, therefore maximum positioning accuracy; no stick-slip effect Concentricity and axial runout accuracy < 0.5 µm
