The general operation process of the rotary table bearing with teeth on the inner ring and outer ring is to mill a notch on the outer ring of the bearing, and install steel ball rolling bodies from the notch. This design scheme is only applicable to the host equipment whose bearing seat rotates horizontally, and the rotating direction is only suitable for one rotating direction, either the bearing rotates clockwise or the bearing rotates counterclockwise, which is greatly limited in the rotating direction. The inner and outer ferrules independently developed and produced by Luoyang East Axis Research Department and Design and Production Department are toothed, and the bearings are vertical and horizontal and can bear radial and axial loads. The bearings with multi-directional loads have been successfully produced and delivered smoothly, and have won high evaluation and recognition from host customers. Now they have been put into use.
Since the 20th century, the development of Luoyang East Axis has focused on greatly improving the output and technical level, increasing the market share of supporting bearings for key mainframes, and marching into the high-end bearing markets such as high-precision turntable bearings, high-power wind power bearings, precision CNC machine spindle bearings, and special bearings for industrial intelligent robots. RU445G/RU445X is the bearing model produced by Luoyang east shaft. the specific parameters of RU445 bearing are introduced as follows
Luoyang east axis RB11020 type bearing, the product specification is 110*135*12, the bearing weight is 0.4kg, the volume of the bearing is relatively small compared with the turntable type bearing, the bearing height is 12mm, it belongs to thin-wall series bearing, and the radial basic rated load is 24.1KN, which bears a larger load than the angular contact bearing with the same size and precision. The internal rolling bodies are cross-arranged cylindrical rollers, which are also called equal cross-section bearings. And the ferrule adopts quenching heat treatment process. The material has high surface hardness, wear resistance and corrosion resistance. Guarantee for one year.
Because of its small size, this type of bearing is usually sealed by vacuum packaging, which plays a role in preventing moisture and corrosion. Compared with other mechanical products, RB12012 bearing parts have the characteristics of simple structure and regular shape, and the processing equipment is mostly professional equipment, which has high production efficiency, easy adjustment and simple operation, and is convenient for realizing mechanized and automated on-line production. The machining precision and surface quality are high. Although the structure of rolling bearing parts is simple, the application occasions are uncertain and the required precision is different. In order to meet most application requirements, the machining accuracy and surface quality of bearings are strict, and many accuracy requirements should be based on micrometer. There are many processing procedures and a long production cycle. In order to obtain the required processing quality, many surfaces of rolling bearings are processed several times. In order to prevent deformation, aging treatment procedures need to be added after some procedures. Therefore, a set of bearings needs at least 20 procedures from feeding to assembly, with a production cycle of about 20 days.

Usage characteristics: the divided inner ring (or outer ring) is fixed with the cross roller collar after the rollers and spacer are installed, so as to prevent mutual separation, so the operation is simple when installing the cross roller collar. The mutual friction between the rollers is eliminated by the spacer, and the rollers are prevented from falling sideways, so that a stable rotating torque can be obtained. Because the rollers are arranged crosswise, only one set of crossed roller bearings can bear loads in all directions, and the rigidity is increased by 3-4 times compared with the traditional model.

The installation of this series of bearings is relatively simple, which is particularly convenient for maintenance. The inner roller, spacer or retainer are fixed with the inner ring, which makes it easy to disassemble and install. With the use of the internal bearing retainer, the grinding force between scattered rollers is reduced, and the noise is also reduced a lot.
