Mining machinery

Where mining machinery and engineering machinery are active, most of them are mining sites far away from ordinary human life, such as mountain areas and desert areas. Sometimes they even work 2000 meters underground. There are many kinds of such machinery, from mineral crushing machinery to cutting machinery, screening machinery, loading machinery, conveying machinery, etc., all of which operate continuously 24 hours a day. The failure of any of these machines will have a great impact on the production at the mining site. Moreover, due to the recent large-scale machinery, the maintenance operation has become very difficult.

Therefore, in terms of the service environment of bearings, there are many very harsh conditions for bearings, such as "heavy load+impact load", "light load+high-speed rotation", and "heavy load+low-speed rotation". Therefore, the bearings that users desire are products with robustness, durability and high reliability that can withstand these harsh working conditions.

In order to meet these needs of users, we have been integrating our core technologies, namely material technology, lubrication technology, analysis technology, with the most advanced bearing design technology, and committed to relevant research and development. As a result, the goal of providing products that greatly exceed the "long life and high limit speed" level of the previous bearings has been achieved, contributing to improving the production efficiency of mining sites in harsh environments and reducing maintenance costs for customers. In addition, NSK also provides new solutions corresponding to environmental requirements.
