There are many types of metallurgical equipment, not only the equipment required by the raw material plant, but also the equipment required from the upstream process to the downstream process such as the steelmaking process, the steel rolling process, and the leveling process. These equipments are equipped with various bearings. These bearings are used under "iron powder", "water", and "hot" conditions unique to metallurgical equipment, and must meet the requirements of "heavy load + vibration and shock", "from ultra-low speed to high speed + rapid acceleration and deceleration", etc. Conditions, used in the very harsh working conditions it holds. "Stable operation and improvement of production efficiency" can be described as the proposition of a representative industry in the field of metallurgical equipment.

In the steel industry, bearings are used in harsh working conditions. In addition to bearing fine iron powder, moisture, and high temperature, they also need to bear high loads, shock loads, strong vibrations, and periodic rapid acceleration and rapid deceleration. Bearings generally require long life and reliability high. Few industries can compare with the harsh working conditions of steel and other metal plants. Temperature and speed limit. Heavy and continuous impact load. Grinding dust, corrosive chemicals and high humidity. The combined effect of these conditions reduces the performance of the equipment, resulting in unplanned shutdowns, and it is difficult to carry out effective equipment maintenance.

The types of bearings used in the metallurgical industry are: deep groove ball bearings, angular contact ball bearings, thrust ball bearings, needle roller bearings (needle roller bearings), thrust roller bearings, spherical roller bearings, tapered roller bearings, Cylindrical roller bearings, vertical self-aligning bearings with seat, outer spherical bearings with seat, bearings for metallurgical equipment.
