The Application of ZWA Paper-making Bearings
Top Chinese Paper-making Bearings
ZWA will continue to develop highly reliable bearings that will lead to further productivity improvements in the papermaking industry, and it will continue to contribute to the development of the industry.
Current Situatuin of Chinese Paper-making Bearings
The characteristics of modern paper machine are: high speed, wide width, continuous, professional. In recent years, Chinese paper market is booming. But domestic paper machine and imported paper machine, has always been occupied by imported brand bearings, domestic bearings are difficult to shake up the position of imported bearings, from the host supporting to terminal maintenance, almost reached a consensus that “imported bearings must be used”. From pulp to finished paper of the whole production line, it is almost difficult to see the figure of domestic bearings. The annual output and consumption of bearings in China have long been ranked first in the world, but it is difficult to get the first place in some really important industries.
Technical Requirements for Paper-making Bearings
Paper production line requires continuous production, especially professional corrugated paper machine, copper sheet paper machine, culture paper machine and so on is a very huge production line, each roller is often hundreds, a production line used bearings is a large number of models, From the wet end of the forming roller, vacuum roller, drive roller, to press section at the center of the squeezing roller, boots, controllable high roller, roller and cadre’s moving roller, cylinder, guide roller and molding department of sizing, calender roller, paper roller, as well as a multitude of guide roller, the working condition of the function of the roller and alone is varied, the bearing is used in the multifarious, and once the bearing appear problem, It will affect the operation of the whole production line, and even cause abnormal shutdown, with huge loss. Therefore, paper machine bearings have always been the world of imported bearings, because imported brand bearings do have very stable quality and life.
