YRTSM series rotary table bearing

Compared with YRT series rotary table bearing, YRTSM series bearing is one kind of high-speed turnable bearing. The limit speed of YRTSM bearing is much higher than that of YRT bearings while the friction torque of YRTSM series rotary table bearing is lower, more even and stable. YRTSM series rotary table bearings can carry combined axial and radial loads, and have the advantages of high tilt rigidity and high precision. Therefore, it is widely used in high-precision CNC equipments,and measurement equipment.

YRTSM series rotary table bearing is the measuring system bearings with SRM measuring electronics for incremental, magneto-resistive angular measurement. YRTSM measuring system bearings allow accurate and reliable angle measurement directly on the machine tool spindle, thereby achieving extremely high machining quality and high machine tool utilization.
