Pulp & Paper

In recent years, in order to improve production efficiency, paper machines have been evolving towards higher operating speeds and wider web widths. Furthermore, to minimise downtime caused by unexpected faults, the reliability requirements for bearings used in paper machines have become increasingly stringent. The bearings used in the drying rolls of paper-making machinery are subjected to high temperatures, as high-temperature steam flows through the interior of the rolls. Consequently, bearings may suffer premature film separation due to an insufficient lubricating oil film, or experience creep caused by ageing from prolonged exposure to high temperatures. Furthermore, temperature differentials between the shaft and the inner ring can lead to increased fitting stresses, resulting in damage such as cracks in the bearing inner ring. In particular, cracks in the inner ring can trigger major accidents leading to production stoppages.

The pulp and paper industry relies on critical process machinery, which typically operates under harsh conditions; consequently, bearing service life is significantly reduced, making reliability of the utmost importance. We not only possess in-depth industry knowledge but also offer a wide range of products and services tailored to various application equipment, helping to improve production efficiency and reduce maintenance costs. To ensure production efficiency and profit margins, pulp and paper companies need to focus on the correct selection of bearings, as well as their proper installation, lubrication, and meticulous monitoring and maintenance, thereby achieving maximum equipment utilisation.
