The places where mining machinery and construction machinery are active are mostly mining sites far away from ordinary human life, such as mountainous areas and desert areas, and sometimes even work at 2,000 meters underground. There are many kinds of such machinery, ranging from mineral crushing machinery to cutting machinery, screening machinery, loading machinery, conveying machinery, etc., all of which are continuously operated 24 hours a day. The failure of any of these machines will greatly affect the production at the mining site, and the recent increase in the size of the machines has made maintenance work very difficult.

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

In order to meet these needs of users, it has been integrating its own core technologies, namely material technology, lubrication technology, analytical technology and advanced bearing design technology, and is committed to related research and development. As a result, the goal of providing products with a "long life and high limit rotational speed" that greatly exceeds the conventional bearings has been achieved, contributing to improving the productivity of mining sites in harsh environments and reducing maintenance costs for customers. In addition, new solutions for environmental protection requirements are also provided.
