compared with YRT types rotary table bearing, YRTSM types bearing is one kind of high speed turnable bearings. the limit speed of YRTSM bearing is much higher than that of YRT bearings while the friction torque of YRTSM types rotary table bearing is lower, more even and stable. YRTSM types 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.
turntable bearings are usually mounted directly onto a structure, and the rotating component is mounted on the inner or outer ring of the bearing. this allows the entire structure to rotate smoothly. turntable bearings are equipped with sealing arrangements to protect the internal components from contaminants, ensuring smooth operation and extending the bearing lifespan.
YRTM rotary table bearings are low friction, ready-to-fit, greased bearing units with high accuracy for very high speeds, high axial and radial loads and high demands on tilting rigidity. Axial-radial bearings with angular measuring system YRTM and YRTSM correspond in mechanical terms to series YRT and YRTS but are additionally fitted with an angular measuring system.
