There are many kinds of metallurgical equipment, including not only the equipment required by the raw material plant, but also the equipment required for steelmaking process, steel rolling process, leveling process and so on from upstream process to downstream process. These devices are equipped with various bearings. Under the special working conditions of "hot metal + hot metal" and "hot metal + hot metal", the bearing can be used under the conditions of "shock + hot metal" and "hot metal + hot metal".

"Stable operation and improving production efficiency" is a proposition of representative industries in the field of metallurgical equipment. Taking this proposition as the goal to make contributions, we not only promote the high degree of bearing design technology, but also promote the corresponding measures and R & D work every day from various internal angles such as bearing material technology, lubrication technology and analysis technology. Therefore, it has been committed to solving the problem of "long life and high reliability of bearings" for a long time.

It has a strong product lineup of bearings required by various metallurgical equipment, including various products from standard bearings of ISO specification to high-function special bearings independently developed. In addition, we also take corresponding measures and provide new solutions to the recent demand for high value-added products and environmental protection products in the metallurgical industry.

The rolling process of rolling the heated steel plate by rolling is also a representative process in the use of dynamic metallurgical equipment, and it is also an important process that has a great impact on the quality of the final product. Four row tapered roller bearings are mainly used at both ends of the main roll. The service conditions of bearings are also representative in metallurgical equipment. They not only need to bear heavy load, but also need to be used under the harsh working conditions of cooling water and foreign matter (iron powder) erosion.

Since a long time ago, we have been committed to the long-life research and development of this four row tapered roller bearing. In the 1970s, it took the lead in developing the "sealed four row tapered roller bearing" with oil seal to prevent water and foreign matters (iron powder) from invading, realizing the leap forward development of prolonging the service life of the bearing. Later, the special grease for the sealed bearing was introduced. In the 1990s, the internal design of the bearing was improved, its rated load was greatly increased, and a new material with strong resistance to iron oxide chips was developed. In recent years, new materials with good resistance to foreign matters (iron powder) and cooling water have also been developed.

In the future, we will continue to develop hand in hand with customers with the goal of becoming an enterprise deeply loved and trusted by customers.
