Problems needing attention in using MTO-122 bearing;
(1) the possible fractal characteristics of the structure of 1)MTO-122 turntable bearings and the possible resolution-dependent characteristics of specific metallographic observation: the quantitative analysis results of the bearing steel structure may be strongly dependent on quenching heat treatment process, which should be paid more attention when carrying out quantitative analysis of the fracture surface structure of bearing materials and storing and processing digital image files of bearing measurement;
(2) Limitations of non-quantitative research on the organizational structure of bearing material assemblies: Although qualitative research on bearing organization is fashionable and can meet the needs of engineering fittings of bearing materials, scientific analysis and research on materials always need scientific quantitative measurement of the geometric shape of bearing organization and error analysis of the obtained quantitative analysis results (random error, systematic error and gross error);
(3) Material bearing MTO-122 bearing organizational structure section or limitations of appearance observation, etc. It is easy for people to misinterpret the performance of section bearings or turntable bearings.
MTO-122
Turntable bearing
MTO series turntable bearings are divided into two types: cylindrical cross roller bearings and tapered cross roller bearings. Generally, the price of cylindrical crossed roller bearings is lower than that of tapered crossed roller bearings, which is suitable for turntable applications with relatively low rotating speed. However, the tapered cross roller bearing adopts the pure rolling design of tapered roller, which has the advantages of high running precision, strong rotating speed capability, reduced shaft length and processing cost, etc. Cross roller bearings are suitable for various types of vertical or horizontal boring machines, as well as vertical mills, vertical lathes and large gear milling machines.

The MTO-122 turntable bearing is a thin-walled bearing family composed of seven open series and five sealed series. There are three types of open series: radial contact type, angular contact type and point contact type. Advantages of thin-walled turntable bearing: the turntable bearing realizes extremely thin bearing section, and also realizes miniaturization and lightweight of products. The variety of products expands its application range.
Features of bearing: In order to obtain low friction torque, high rigidity and good rotary precision, steel balls with small outer diameter are used. The use of hollow shaft ensures light weight and wiring space. The 6700 and 6800 series of this model have various dust cover forms, flanged forms, stainless steel forms, wide forms, etc.
Main uses of MTO series bearings: stepping motor, medical equipment, office equipment, testing instrument, speed reducer, speed changer, robot, optics, imaging equipment and rotary encoder.
It has high precision, very quiet and strong bearing capacity. The bearing ring can be, and the cross section of the bearing is mostly square. In these series, the cross section remains unchanged even with larger shaft diameters and bearing holes. It is this characteristic that distinguishes thin-walled ring bearings in the standard ISO series from traditional bearings. Therefore, it is possible to choose a larger bearing and use a bearing with stronger load-carrying capacity without changing the shaft diameter. Turntable bearings can be designed to be extremely light and require little space.
