The places where mining machinery and construction machinery are active are mostly mining sites far away from ordinary human life such as mountainous and desert areas, and sometimes even work at 2,000 meters underground. There are many types of this kind of machinery, from mineral crushing machinery to cutting machinery, screening machinery, loading machinery, conveying machinery, etc., all of which operate continuously 24 hours a day.

Any failure of any of these machines will have a great impact on the production at the mining site. In addition, due to the recent increase in the size of the machines, maintenance operations have become very difficult.

Therefore, in the bearing environment, "heavy load + impact load", "light load + high-speed rotation", "heavy load + low-speed rotation", etc., have many very harsh conditions for the bearing. 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 always integrated our core technology, namely material technology, lubrication technology, analysis technology and bearing design technology, and devote ourselves to related research and development. As a result, the goal of providing products that greatly exceed the level of "long life and high limit speed" of previous bearings has been achieved, contributing to improving the production efficiency of mining sites under harsh environments and reducing maintenance costs for customers. In addition, Provide new solutions corresponding to environmental protection requirements.
