Turntable bearing is a kind of bearing that can bear the combined load bearing axial load, radial load and overturning moment at the same time. It is a precision bearing with special structure including support, rotation, transmission and fixing. 

Rotary table bearing negative preload with the basic design of preload to ensure high bearing rigidity and rotation accuracy; under normal circumstances, the inner and outer ring turntable bearings with mounting holes, lubricating holes and sealing structure for precision working conditions Turbine bearing has the advantages of compact structure, high rotation precision, easy installation and maintenance, etc. The rotary bearing mainly includes YRT turntable bearing, ZKLDF turntable bearing and crossed roller bearing. The three series of bearings have the same installation dimensions, internal structure differences, similar performance.
