YRT bearings (rotary table bearings) are axial and radial combined cylindrical roller bearings, including two thrust needle roller bearings and a radial cylindrical roller bearing with the combination of axial and radial pre-load.YRT bearings offer advantages such as high axial and radial load capacity, high tilted rigidity and high precision. The rotary table bearings are especially suitable for precision machine tools, rotary worktables or as indexing plates on other types of precision machines. Other possible uses may include measuring instruments and test equipment on rotary table configurations
