Paper-Making Machinery
In recent years, to improve production efficiency, paper machines have been evolving toward higher operating speeds and wider widths. Additionally, to minimize downtime caused by unexpected failures, bearings used in paper machines are required to offer higher reliability. Bearings used in the drying rolls of paper machines are subjected to high-temperature environments because high-temperature steam passes through the rolls. Consequently, these bearings are susceptible to premature failure due to insufficient lubrication film formation, creep caused by prolonged exposure to high temperatures, and increased fitting stress resulting from temperature differentials between the shaft and inner ring, which can lead to cracks in the inner ring. In particular, inner ring cracks can cause major accidents that result in production shutdowns.
The pulp and paper industry relies on critical process machinery, which typically operate under harsh conditions. Consequently, bearing service life is significantly shortened, and reliability is of the utmost importance. With deep industry knowledge and a wide range of products and services tailored to various application equipment, we help improve production efficiency and reduce maintenance costs. To ensure production efficiency and profitability, pulp and paper companies must focus on the correct selection of bearings, as well as proper installation, lubrication, careful monitoring, and maintenance to achieve maximum machine utilization.
Utilizing advanced heat treatment processes, we meet the specific demands of the pulp and paper industry. Drawing on expertise rooted in knowledge and experience, we provide bearing technology and services tailored to heavy industrial applications, serving pulp and paper customers across the sector.
