YRT 50 Rotary Table Bearing For Machining Center Axial Turntable

The YRT50 turntable bearing consists of a thrust/centre seat, a thrust/centre shaft ring, a thrust washer, two needle roller cage assemblies and a set of centripetal cylindrical rollers. The seat ring and shaft ring have uniform mounting screw holes. This type of bearing has high axial and radial load carrying capacity. High tilt stiffness and extremely high accuracy. Suitable for rotary table, chucks and iron heads as well as bearing arrangements for measurement and experimentation.

YRT turntable bearing is a type of rotating mechanism with outer ring rotation and inner ring support. It is mainly divided into three series: YRT type, YRTS type and YRTM type. These three series bearings have the same installation size, internal structure difference, and similar performance. YRT series bearings are composed of three rows of rollers (as shown on the right). Two rows of axial rollers ensure stable axial load-carrying capacity. One row of radial rollers ensures that the bearings can withstand radial forces and tilting moments. They are suitable for axial load carrying. The slewing mechanism.

The YRT50 turntable bearing consists of a thrust/centre seat, a thrust/centre shaft ring, a thrust washer, two needle roller cage assemblies and a set of centripetal cylindrical rollers. The seat ring and shaft ring have uniform mounting screw holes. This type of bearing has high axial and radial load carrying capacity. High tilt stiffness and extremely high accuracy. Suitable for rotary table, chucks and iron heads as well as bearing arrangements for measurement and experimentation. This type of bearing also has high requirements for the matching equipment parts. When installing, it is necessary to control the tightening torque of the mounting screws.
