YRT basic rotary table Bearings are designed with a radial full roller, two groups of axial needle Roller, cage assembly, an out ring, a L-section Inner ring and the second ring. the out ring and inner ring have fixing holes. Added preload after fitting simplified the unit construction,Shorten the work of fixing, Lowered the high on fixing. so this kind of bearing is particularly suitable for the situatin of High precision, high stiffness and the Union loads with low speed such as index tables and revolving milling heads.See Fig
*this kind of Bearing have axial and radial running precision for your chosen.
