YRT Turntable Bearing feature:

YRT turntable bearings are a kind of slewing mechanism that rotates on the outer ring and are supported by the inner ring. They are mainly divided into three series: YRT, YRTS and YRTM. These three series of bearings have the same installation dimensions, internal structure differences and similar performance. The YRT series bearings are composed of three rows of rollers. Two rows of axial rollers ensure stable axial load carrying capacity. The rows of radial rollers ensure that the bearings can withstand radial forces and overturning moments. They are suitable for axially loaded rotary mechanisms. YRT turntable bearings are mainly used in CNC machine tool manufacturing.

The YRT turntable bearing consists of 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 high accuracy. Suitable for rotary tables, chucks and milling heads 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.

YRT Turntable Bearing application:

It is widely used in precision devices such as precision rotary table CNC turntable, vertical grinder, indexing head, gear hobbing machine, milling machine workpiece shaft, etc.
