In recent years, the paper industry has improved the production efficiency, paper machinery high-speed development. In addition, in order to reduce the downtime caused by unexpected faults, paper machinery bearings are required to have higher reliability.

NSK has a range of products to meet these needs, paper production lines are equipped with all parts of the NSK bearings. In particular, the application and development of NSK material and heat treatment technology, dry special bearing "TL(TC and long life bearing" and a group of material technology, design technology, manufacturing technology comprehensive ability development of "mechanical industry high performance standard bearing NSKHPS spherical roller bearing", in the paper industry support process plays an important role.

NSK s performance and innovative technology will continue to develop and improve the production efficiency in the future, which is closely related to the high reliability bearing, and always contributes to the development of paper industry.

TL bearings

Paper machine for the dry roller bearings, due to the high temperature steam through the roller, bearing in the high temperature environment. Therefore, the bearing will lack of separation due to the formation of lubricating film, and creep caused by long-term high-temperature use will also occur. The pressure of rising temperature of the shaft and inner ring will increase, leading to cracks in the inner ring of the bearing. In particular, cracks in the inner ring can cause major accidents, leading to production stoppages. As the measures to solve these problems, NSK through special material of carbon and nitrogen nitriding technology, developed the high hardness (TL) TC bearing long life of crack resistance and high hardness, high temperature resistant, crack resistance of reinforced material that TL bearings, in similar products, with the best reliability, can be used for drying, the hydraulic oil cylinder roller bearing application of papermaking machine a stable position in the market.
