There are many kinds of metallurgical equipment, including not only the equipment needed by the raw material factory, but also the equipment needed from the upstream process to the downstream process, such as steelmaking process, steel rolling process and leveling process. These bearings are used under the special conditions of iron powder, water and heat of metallurgical equipment, so they need to meet the requirements of heavy load , vibration shock, from ultra-low speed to high-speed & rapid acceleration and deceleration. "Stable operation and improved production efficiency" can be described as a representative industry in the field of metallurgical equipment. ZYS is not only in bearing design technology, but also in various aspects such as bearing material technology, lubrication technology, and analytical technology.
