Product description

Rotary table bearing YRT
It is defined as the combination of double-row axial and single-row radial roller turntable bearing.

YRT turntable bearing is a kind of structure with outer ring spinning and inner ring supporting, mainly divided into YRT, YRTS and YRTM three series. The three series of bearing have the same installation size and similar performance, but their internal structures are different. YRT series of bearings are all composed of three rows of rollers (Like the picture on the right), of which double-row axial rollers can ensure the stability of the axial bearing capacity, and the rest single row radial roller can ensure radial force and overturning moment effect, which is suitable for axial bearing slewing mechanism.
YRT turntable bearing is mainly used for NC machine tool manufacturing industry, as the core component, domestic demand for YRT series bearings mainly depend on import, domestic YRT accuracy parameter standard of turntable bearing also will be subject to international manufacturers. Since entering the 21st century, especially as the startup of country "high-grade CNC machine tools and basic manufacturing equipment" special project, greatly promoting the development of the machinery and equipment industry, the development process of the" high-speed, precision, composite, intelligent" machine tool has been further accelerated. There will be new development opportunities and challenges for turntable bearing.

Product Application:
YRT bearings are suitable for the axial and radial bearing. The characteristics of high rigidity and precision, makes it very suitable for rotary table, chuck, iron cutting tools and the bearing configuration in the measurement and experiment. This type of bearing has higher requirements for the parts of the equipment. Tightening torque of the screw needs to be under control when installed. YRT bearings are mainly used in high precision NC rotary table, dividing head, military radar, aviation, aerospace, and the fields requiring high precious during measurement and test.
