Turntable bearings and crossed roller bearings are similar in function and structure, such as high rigidity, high precision, and high speed. More and more traditional designs have been abandoned in high-precision CNC machining equipment such as CNC indexing plates, vertical machining centers, vertical grinding machines, and high-precision crossed roller bearings and YRT rotary table bearings with better performance.
YRT rotary table bearing is also called a rotary table bearing or a slewing bearing. It is a bearing type similar to a three-row roller combination slewing bearing structure. Compared with the slewing bearing of the three-row roller combination structure, it has a small size and a high precision level. High rigidity, large load carrying capacity and resistance to damage. Mainly used in high-precision CNC rotary table, CNC indexing plate, vertical machining center, vertical grinding machine, radar, high-precision medical equipment.
Cross-roller bearings are also called cross-roller bearings. The rolling elements are generally arranged with a cylindrical roller or a tapered roller on a single raceway. The roller and the roller are separated by a retainer or a spacer. High rotation accuracy, large bearing capacity, small form factor and high rotational speed and rigidity have a wide range of applications. It is suitable for industrial robots, welding robots, medical equipment, etc., where the load is slightly smaller and the accuracy level is slightly lower.
YRT rotary table bearings and crossed roller bearings have the unsurpassed advantages of traditional bearings in all aspects.
In terms of structure, the YRT rotary table bearing and the cross-roller bearing structure are much simpler than the conventional bearings. By the arrangement of the cylindrical rolling bodies arranged in multiple rows, considerable axial and radial bearing capacity and overturning moment can be obtained, and the structure is relatively simple. Much, and the traditional bearings must be arranged through multiple sets of bearings in order to achieve the same effect, which brings great convenience in design and assembly and installation. YRT bearing three-row roller combination slewing bearing structure and cross-roller bearing single-row raceway structure, compared with the traditional bearing, occupying equipment space is much smaller, the assembly difficulty is also greatly reduced.
