Obecnie w przemyśle maszynowym spotykane są wielkogabarytowe stoły obrotowe. Takim typowym przykładem są tokarki karuzelowe w całym zakresie ich typów i wielkości. Oprócz tego stoły te stanowią, wyposażenie obrabiarek, np. wiertarko-frezarek.
The engineering industry uses different rotary tables in practice. They are used as parts of vertical lathes, or as equipment for other machine tools. The diameters of these tables can reach the size of up to several dozen meters and the load capacity of up to several dozen tonnes. The main element transferring the table load during operation is a large size thrust bearing. Ball or spherical roller bearings are most often used in the construction of rotary tables. When transferring large loads between rolling elements and raceways, there are high point surface pressures. This creates local deformations which have a negative effect on the accuracy of the work pieces. A hydraulic thrust bearing made of two steel bearing rings does not have such a disadvantage. The stationary lower ring is attached to the lathe body and the steel upper ring is lined with plastic to the rotary table. The principle of operation of the hydraulic bearing is that between these two rings oil is fed under pressure during operation. This creates a very thin layer of oil between the rings, which transfers the load and lubricates at the same time. The oil is fed continuously during machine operation and circulates in a closed circuit. This solution is cheap, simple in construction and has a long service life.
