The rotary table bearing is a bearing that can simultaneously bear the combined load of axial load, radial load and overturning moment, etc. It is a precision bearing with a special structure that integrates support, rotation, transmission, and fixed functions. The turntable bearing basically adopts the design method of negative clearance with preload to ensure the high rigidity and rotation accuracy of the bearing; under normal circumstances, the inner and outer rings of the turntable bearing have mounting holes, lubricating oil holes and sealing structures, which are suitable for precise working conditions. Different installation and use requirements of various types of equipment; turntable bearings have the characteristics of compact structure, high rotation accuracy, easy installation and maintenance, etc. The turntable bearings mainly include YRT turntable bearings, ZKLDF turntable bearings and cross roller bearings. The three series bearings have the same installation size, internal structure is different, and performance is similar.

Application: It is widely used in precision rotary table vertical grinding machines, indexing heads, gear hobbing machines, gear milling machine workpiece shafts and other precision devices.
