In the steel industry, bearings can be found in a vast range of plants and equipment that is used in both upstream and downstream processes: from the storage yard for raw materials to the steelmaking, rolling and refining processes. The operational environment for these bearings is unique to steelmaking, comprising steel dust, water and heat. In addition, the bearings may have to cope with heavy loads and vibration shock, operational speeds ranging from extremely slow to extremely high, coupled with rapid acceleration and deceleration. This makes for a demanding operational environment that is not found in other applications.
NSK aims to make a positive contribution to improving operational stability and productivity, issues that are crucial to the steel industry. NSK achieves this by applying high-level bearing design technologies and on-going planning, development and R&D from many different perspectives, including bearing technologies of materials, lubrication and analysis. NSK responds to the need for high added-value products and an environmentally friendly approach in the steel industry.

Bearing Solutions for Metals Industry
In the dynamic steelmaking environment, rolling is a typical process. In the rolling process, red-hot steel is squeezed between rollers, making it longer and thinner. This is a crucial process that greatly influences the quality of the final product. On both sides of the main rollers, four-row tapered roller bearings are generally used to cope with the heavy loads and the exposure to cooling water and mill scale.
NSK has worked to provide solutions to these conditions. We have worked to increase the life expectancy of the four-row tapered roller bearings. In the 1970's the company developed, as a world first, Sealed-Clean™ Four-Row Tapered Roller Bearings, complete with oil-sealing equipment to prevent the intrusion of water and mill scale. This greatly extended the life of roller bearings.
Subsequently, NSK released special greases for the Sealed- Clean™ bearings. In the 1990's the company substantially improved the load rating of bearings through an internal design improvement, and it also developed new scale-resistant materials. In recent years NSK has also developed new materials with resistance to cooling water processes.
Whether your bearings are suffering from contamination and over consumption of grease in your roll neck applications, excessive loads and heat in your continuous castor, or if you're just looking for a fresh approach to achieving maximum bearing uptime, Think NSK for the solution.
