There are many kinds of metallurgical equipment, not only for raw materials, but also for steelmaking, steel rolling and equal-process. These devices are fitted with various bearings. These bearings are used in metallurgical equipment is special "iron", "water" and "hot" conditions, but also to meet the "heavy load + vibration impact", "from ultra-low speed to high speed + rapid acceleration and deceleration" conditions of use, in its holding conditions are very harsh conditions of use.

"Stable operation, improve production efficiency", in the field of metallurgical equipment can be said to be the representative of the industry positioning. With this proposition as its goal, NSK has not only made contributions to the height of bearing design technology, but also from various perspectives of bearing material technology, lubrication technology, analysis technology and daily development to corresponding measures and research. Therefore, NSK company has long been committed to solving the problem of long life and high reliability of bearings, which is an eternal topic.

NSK has a wide range of bearings for metallurgical equipment, including ISO specifications, from standard bearings to development of products such as high-function bearings. In addition, we also need to take appropriate measures to provide new solutions for the recent high value-added products and environmental protection products in the metallurgical industry.

NSK's performance and innovative technology

The combination of heating plate and strip rolling process is a representative process in dynamic metallurgy equipment, and it is also the most important process affecting the final product quality. Two ends of the main roller, mainly using four row tapered roller bearings. Bearing conditions of use, in metallurgical equipment also has a certain representative, not only need heavy load, but also in the use of harsh conditions of cooling water and foreign matter (iron powder) erosion.

Since many years, NSK has been committed to the research and development of four row tapered roller bearings with long life. In the 1970s, the world was the first to develop a "sealed four-row tapered roller bearing" to prevent the invasion of water and foreign substances. Later, in the 1990s, the sealed type bearing with special grease was introduced. At the same time, the internal design of the bearing was improved, the rated load was greatly increased, and the powerful capacity of new materials of iron oxide was developed. In recent years, corrosion resistance of new materials to foreign matter (iron) and cooling water has also been developed.

In the future, NSK will continue to take the customer's affection and the enterprise's trust as the goal, advances together with the customer.
