The YRT1030 turntable bearing consists of a thrust/centre seat, a thrust/centre shaft ring, a thrust washer, two needle roller cage assemblies and a set of centripetal cylindrical rollers. The seat ring and shaft ring have uniform mounting screw holes. This type of bearing has high axial and radial load carrying capacity. High tilt stiffness and extremely high accuracy. Suitable for rotary table, chucks and iron heads as well as bearing arrangements for measurement and experimentation. This type of bearing also has high requirements for the matching equipment parts. When installing, it is necessary to control the tightening torque of the mounting screws.
