In the steel industry, QJ228 Bearing can be found in a vast range of plant and equipment that is used in both upstream and downstream processes: from the storage yard for raw materials to the steelmaking, rolling and refining processes. All kinds of bearings are used in this plant and equipment.
The operational environment for these bearings is unique to steelmaking, comprising steel dust, water and heat. In addition, the QJ228 Bearing may have to cope with heavy loads and vibration shock, operational speeds ranging from extremely slow through to high, coupled with rapid acceleration and deceleration. This makes for a demanding operational environment that is not found in other applications.
QJ228 Bearing aims to make a positive contribution to improving operational stability and productivity. These are issues crucial to the steel industry, which is representative of the industry which manufactures production equipment. QJ228 Bearing achieves this aim by
