YRT series turntable bearing with a set of radial roller, two groups of thrust roller cage full components of composite structure design, an outer ring, a l-shaped inner ring and the inner ring, inner and outer ring with mounting holes, and before delivery or addition of pre-load, not only simplify the structure of the components, reduced the workload of installation, reducing the high requirements for installation.Therefore, for low-speed and short-time operation occasions with high precision, high rigidity and bearing joint load requirements, such as dividing table and rotary milling head, it is extremely suitable to choose YRT series rotary table bearing.

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.
