Product Description

Rotary table bearing 
     ZYS rotary table bearings are axial/radial cylindrical roller bearings, are composed of two thrust roller bearings and a radial cylindrical roller bearing with the combination of axial and radial preload. For the convenience of transportation and mounting, use two or three symmetrical fixing screws to fasten the two shaft washers in order to prevent collision between rolling elements and rings, and avoid bad influence on bearing accuracy. This kind of bearing can support great radial and axial pressure and overturning moment with high rigidity, so it is especially used for large rotary table and large turntable.
