Mining machinery field

Mining machinery and construction machinery are active in many areas, such as mountainous areas and desert areas, which are far away from the ordinary life of human beings. Sometimes they even work 2000 meters underground. There are many kinds of such machines, ranging from mineral crushing machinery to cutting machinery, screening machinery, loading machinery, conveying machinery, etc., which are continuously running 24 hours a day. No matter which kind of machinery breaks down, it will have a great impact on the production of the mining site. Moreover, due to the recent large-scale machinery, maintenance work has become very difficult.            Therefore, in the use environment of bearings, "heavy load + impact load", "light load + high-speed rotation", "heavy load + low-speed rotation" and so on are very harsh conditions for bearings. Therefore, the bearings that users desire are the products with strong, durable and high reliability which can resist these bad working conditions.            In order to meet these needs of users, we have been integrating our core technology, i.e. material technology, lubrication technology, analytical technology and the most advanced bearing design technology, and devoted ourselves to related research and development. As a result, the goal of providing products that surpass the previous bearing's "long life and high ultimate speed" level has been achieved, which contributes to the improvement of production efficiency and the reduction of maintenance cost in mining site under harsh environment for customers. In addition, NSK provides new solutions to meet environmental requirements.
