GCr15 high precision rotary table bearing yrt50
YRT150 bearing is a slewing mechanism with outer ring rotation and inner ring support. It is mainly divided into three series of YRT, YRTS and YRTM. These three series of bearings have the same installation dimensions, differences in internal structure 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, and one row of radial rollers ensure that the bearing can withstand radial forces and overturning moments, suitable for axial load Swing mechanism.
Series introduction :YRT turntable bearings are composed of a thrust / radial race, a thrust / radial shaft ring, a thrust washer, two needle roller cage assemblies and a set of radial cylindrical rollers. The seat ring and the shaft ring have evenly distributed mounting screw holes. This type of bearing has high axial and radial load capacity. High tilt stiffness and extremely high accuracy. Suitable for rotary tables, chucks and iron cutters, as well as bearing arrangements for measurement and experimentation. This type of bearing also has higher requirements for the equipment parts that match it. Control the tightening torque of the mounting screws during installation.
