Strict working conditions and market conditions, therefore, in the bearing environment, “heavy load + shock load”, “light load + high-speed rotation”, “heavy load + low-speed rotation” are very harsh conditions for bearings. a lot of. Therefore, users want bearings with robustness, durability and high reliability that can withstand these harsh operating conditions. In order to meet these needs of users, we have been combining material technology, lubrication technology, analysis technology and more advanced bearing design technology to contribute to improving mine site production efficiency and reducing maintenance costs for customers in harsh environments.
