There are many kinds of metallurgical equipment, including not only the equipment required by the raw material plant, but also the equipment required for the steelmaking process, steel rolling process, leveling process, etc. from the upstream process to the downstream process. These devices 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 operating conditions of "heavy load+vibration and impact", "from super low speed to high speed+rapid acceleration and deceleration", and are used under the very bad working conditions.

"Stable operation and improvement of production efficiency" is a proposition of representative industry in the field of metallurgical equipment. Make contributions to this proposition, not only in terms of high bearing design technology, but also in terms of bearing material technology, lubrication technology, analytical technology and other internal aspects, to promote the corresponding measures and research and development every day. For this reason, we have been committed to solving the problem of "high reliability of bearing with long service life" for a long time.

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

The rolling process of rolling the heated steel plate 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. The two ends of the main roll mainly use four row tapered roller bearings. 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 severe working conditions of cooling water and foreign matters (iron powder) erosion.

Since a long time ago, we have been committed to the research and development of this kind of four row tapered roller bearing. In the 1970s, it took the lead in developing the "sealed four row tapered roller bearing" with the function of preventing water and foreign matter (iron powder) from invading the oil seal, realizing a leap forward development in extending the service life of the bearing. Later, the special lubricating grease for this sealed bearing was introduced. In the 1990s, the internal design of this bearing was improved, its rated load was greatly increased, and new materials with strong resistance to oxidized iron filings were 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 our customers with the goal of becoming an enterprise deeply loved and trusted by our customers.
