Reliable bearing systems for suction rolls – the key to efficient paper machine operation

In modern paper machines, the number of bearings can reach several hundred. Few realize that the performance of the entire paper machine can depend on each of these components, which may seem insignificant at first glance. Bearing support for rolls is not just about enabling rotation — it is the foundation of smooth and reliable operation under harsh industrial conditions. Poorly designed bearing systems can cause serious failures in the paper forming section, leading to costly production downtime. Properly selected bearings significantly increase the efficiency and durability of the entire system.

 

The suction roll in a paper machine plays a vital role in the dewatering process of the wet paper pulp. Its bearing system must withstand radial loads, exposure to water and dust, as well as high rotational speeds. The most used bearings are single- or double-row cylindrical roller bearings, valued for their high radial load capacity, and spherical roller bearings, appreciated for their self-aligning properties and ability to handle both axial and radial loads. Bearing housing is equally important, protecting against contaminants while enabling effective lubrication and heat dissipation.

 

At NG Engineering, we fully understand the critical importance of reliable components such as suction rolls and their bearing systems in industrial machine operation. That is why our solutions are based on extensive experience in machine design, precise bearing selection, sealing technology, and customized bearing housing all easily integrated with existing systems. Leveraging our expertise in machining, structural design, and advanced manufacturing techniques, we deliver equipment that enhances efficiency, minimizes failures, and directly contributes to reducing operational costs.
