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. Any failure of any of these machines will greatly affect the production at the mining site, and the recent increase in 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, DKB has always integrated material technology, lubrication technology, analytical technology and more advanced bearing design technology to contribute to improving the production efficiency of mining sites in harsh environments and reducing maintenance costs for customers.
