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 other processes from upstream to downstream. These equipment are equipped with various bearings. These bearings are used under the special "iron powder", "water" and "hot" working conditions of metallurgical equipment, and also meet the service conditions of "heavy load + vibration impact", "from ultra-low speed to high speed + rapid acceleration and deceleration", and are used under very severe working conditions.

"Stable operation and improvement of 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 corresponding measures and research and development every day in terms of high bearing design technology, but also from various internal angles such as bearing material technology, lubrication technology and analysis technology. For this reason, 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 ISO standard bearings to independently developed high-function special bearings. In addition, we have taken corresponding measures to provide new solutions to the recent demands of the metallurgical industry for high value-added products and environmentally friendly products.

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 final products. 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 loads, 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 research and development of long-life four row tapered roller bearings. 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 a leap forward development in extending 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.
