The places where mining machinery and engineering machinery are active are mostly mining sites away from ordinary human life such as mountains and deserts. Therefore, in terms of the bearing environment, “heavy load + impact load”, “light load + high-speed rotation”, "Heavy load + low speed rotation" and the like are very demanding conditions for bearings. Therefore, the bearings that the user desires are products that are resistant to the harshness, durability, and reliability of these harsh conditions. In order to meet these needs of users, we have always integrated our core technologies, namely material technology, lubrication technology, analytical technology and advanced bearing design technology, and committed to relevant research and development.
