YRTM 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.

YRTM integrated angle measurement system series:

Based on the YRT turntable bearing standard series, an angle measurement system is integrated to achieve accurate angle measurement. The highest accuracy can reach 1 arc second, which is very suitable for applications with high requirements for angular positioning accuracy.

YRTM 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.
