In recent years, the paper industry has been developing paper machines at high speeds and wide widths to improve production efficiency. In addition, to reduce downtime caused by unexpected failures, bearings used in paper machines are required to have higher reliability. The bearings used in the drying rollers of papermaking machinery are exposed to high temperatures due to the passage of high-temperature steam through the rollers. For this reason, bearings may experience early peeling due to insufficient formation of lubricating oil film, creep caused by long-term high-temperature use and aging, as well as increased fitting stress caused by temperature difference between the shaft and inner ring, leading to damage such as cracks in the bearing inner ring. Especially, cracks in the inner ring will cause major accidents leading to production stoppage.

The pulp and paper industry relies on critical process machinery, which typically operates under harsh conditions, resulting in significantly shortened bearing life. Reliability is crucial, as it not only provides extensive industry knowledge but also offers a wide range of products and services for various application equipment, helping to improve production efficiency and reduce maintenance costs. To ensure production efficiency and profit margins, pulp and paper enterprises need to pay attention to the correct selection of bearings, install them correctly, lubricate them, carefully monitor and maintain them, and achieve greater machine utilization.

By adopting improved heat treatment processes, we can meet the needs of the pulp and paper industry. Industrial papermaking is based on knowledge and experience, with expertise in heavy industry applications. We provide bearing technology and services to pulp and paper customers in the pulp and paper application fields.
