Papermaking machinery

In recent years, the paper industry to improve the production efficiency, the paper machine is high high speed wide development. In addition, in order to reduce the downtime due to unexpected failure, the paper mill bearing is required to have a higher reliability.
NSK has a series of products to meet these needs, the various parts of the paper production line machine is equipped with NSK bearing. In particular, the application of NSK materials and heat treatment technology development of drying special bearing "TL (TC & long life bearings" and a set of material technology, design technology, manufacturing technology of comprehensive ability development of the "machinery industry with high performance standard bearing NSKHPS spherical roller bearings", charged with the support of papermaking industry plays an important role in the process of.
NSK in the future will continue to develop and improve production efficiency is closely related to high reliability bearings, and always contribute to the development of the paper industry.
Performance and innovative technology of NSK
TL bearing
Paper machinery for the drying roller bearings, as a result of high-temperature steam through the roller, the bearing to be in a high temperature environment. Therefore, the bearings will be due to the lubricating oil film formed due to the lack of abruption, will also occur for long-term high temperature use aging caused by creep, and the shaft and the inner ring of the temperature rise with the stress increases so that the bearing inner ring crack. In particular, the cracks in the inner ring will cause a major accident causing production shutdown. As a countermeasure to these problems, NSK through the material of special carbon and nitrogen nitriding processing, developed to enhance the inner resistance to cracking and at high temperatures with the dimensional stability of high hardness (TC & long life bearings for long life "TL". This TL bearing, in similar products, with the best reliability, as the drying of the hydraulic cylinder roller bearings, to establish a stable position in the market.
