Pneumatic rotary table

horizontalairaerostatic

Aerostatic rotary tables The aerostatic rotary tables from ZOLLERN impress with their durability and a high concentricity and axial runout accuracy. The freedom from friction at low speeds prevents slip stick and allows maximum positioning accuracy. For aerostatic rotary tables, moving parts and housing are separated from each other by an air gap, independent of the load or sliding speed. There is no direct contact. Sliding bodies or the like are not required. Features Combined radial-axial bearing Bearing surfaces with special synthetic resin sliding layer for the best possible emergency running properties Advantages Concentricity and axial runout accuracy up to < 0.2 µm 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
