YRT rotary table/ turntable bearings are axial and radial combined cylindrical roller bearings, which are fixed by a bidirectional thrust bearing and a centripetal-guided bearing. They can support radial loads, axial loads from both directions and tilting moments free from clearance. For the convenience of transportation and fixing, two or three symmetrical screws are fastened to the two rings in order to prevent rollers and rings generating collisions which influence bearing accuracy.
