A YRTM type bearing must have a variety of properties depending on the environment in which it is used.
1. The rotational speed of the host equipment progress, need to use (below 200 ºC) quasi high temperature bearing steel (usually using in SUJ2 steel on the basis of progress of Si content, add V and Nb methods to achieve the purpose of the softening resistance and stable size);
2. For corrosion applications, the machine tool needs to develop stainless bearing steel;
3. Host for ordinary occasions. In order to simplify the process, high frequency hardening bearing steel and short time carburizing bearing steel should be developed

4. High-temperature bearing steel should be developed to meet the needs of aerospace equipment.

YRTM series bearings require high cleanliness of bearing steel
In particular, reducing the oxygen content in steel can significantly extend the life of the bearing. Oxygen content drops from 28ppm to 5ppm, exhaustion life can extend 1 number level.
In order to extend the life of bearing steel, people have been committed to the development and application of refining technology for many years to reduce the oxygen content in steel. Through unremitting efforts. At present, LYDZC can control the minimum oxygen content in bearing steel at about 10ppm.
