Most of the places where mining machinery and engineering machinery are active are mining sites far away from human ordinary life, such as mountainous and desert areas, and sometimes 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., which operate continuously 24 hours a day. No matter what kind of machinery fails, it will have a great impact on the production of 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 the bearing, "heavy load + impact load", "light load + high-speed rotation", "heavy load + low-speed rotation" and many other very harsh conditions for the bearing. Therefore, the bearing desired by users is a product with firmness, durability and high reliability that can resist these harsh working conditions.

In order to meet these needs of users, BLS has always integrated its core technologies, namely material technology, lubrication technology and analysis technology with the most advanced bearing design technology, and is committed to relevant research and development. As a result, the goal of providing products that can greatly exceed the level of "long life and high limit speed" of the previous bearings is realized, which contributes to improving the production efficiency of the mining site and reducing the maintenance cost for customers under harsh environment. In addition, BLS also provides new solutions corresponding to environmental protection requirements.

Mining machinery and engineering machinery are operating at mining sites all over the world. The bearings used in these equipment mainly use ISO standard bearings on the premise of considering the convenience of maintenance. Therefore, BLS has developed standard bearings with BLS high performance to contribute to the mining machinery and construction machinery industry.
