In recent years, in order to improve the production efficiency of the paper industry, paper machines are developing towards high speed and wide width. In addition, in order to reduce the downtime caused by unexpected failures, the bearings used in paper machines are required to have higher reliability.

It has a series of products that can meet these needs, and all parts of the paper production line are equipped with bearings. In particular, "TL (Tough&Long life) bearing", a special bearing for the drying department developed by the applied material heat treatment technology, and "self-aligning roller bearing", which integrates the comprehensive capabilities of material technology, design technology and manufacturing technology, play an important role in supporting the paper industry.

In the future, we will continue to develop high reliability bearings closely related to improving production efficiency, and always contribute to the development of the paper industry.

The bearings used in the drying roll of paper machine should be in a high temperature environment because of the high temperature steam passing through the roll. For this reason, the bearing will cause early peeling due to insufficient formation of lubricating oil film, creep due to aging under long-term high temperature, and the temperature difference between the shaft and the inner race will increase the fitting stress, resulting in cracks on the inner race of the bearing. In particular, cracks in the inner ring will cause major accidents leading to production stoppage. As a countermeasure to these problems, through special carbonitriding treatment of materials, a high hardness and long life "TL (Tough&Long life) bearing" with improved inner ring crack resistance and dimensional stability at high temperatures has been developed. This TL bearing has good reliability among similar products. As a special bearing for the hydraulic cylinder roll of the drying section, it has established stability in the market.
