In recent years, to improve production efficiency, paper machines have been evolving towards higher operating speeds and wider widths. Furthermore, to minimise downtime caused by unexpected failures, the bearings used in paper machines are required to offer greater reliability. The bearings used in the drying rolls of paper machinery are subjected to high temperatures, as high-temperature steam passes through the rolls. Consequently, bearings may suffer from premature separation due to insufficient lubricant film formation, creep caused by ageing under prolonged high-temperature operation, and increased fitting stress resulting from temperature differentials between the shaft and inner ring, leading to damage such as cracks in the inner ring. In particular, cracks in the inner ring can lead to major accidents resulting in production stoppages.

The pulp and paper industry relies on critical process machinery, which typically operate under harsh conditions; consequently, bearing service life is significantly reduced and reliability is of paramount importance. We possess not only 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 profitability, pulp and paper enterprises need to focus on the correct selection of bearings, as well as their proper installation, lubrication, careful monitoring and maintenance, thereby achieving maximum machine utilisation.

Utilising advanced heat treatment processes, we meet the specific demands of the pulp and paper industry. Drawing on our expertise in industrial pulp and paper production, we provide specialised technical solutions and services tailored to heavy-duty industrial applications, serving customers across the pulp and paper sector.
