In the field of steel and non-ferrous metal processing, hot and cold rolling mills operate continuously at high speeds, enduring extreme working environments and immense combined loads. In this critical process, a core component silently supports the stability and efficiency of the entire rolling process – the rolling mill bearing.

As a key load-bearing component connecting the rolls and the mill stand, rolling mill bearings must withstand enormous radial pressure and axial impact simultaneously. Their performance directly determines the reliability, accuracy, and service life of the rolling mill. Currently, the industry mainly uses two major technical approaches: oil film bearings and rolling bearings.  Rolling bearings, due to their high rigidity, ease of maintenance, and energy-saving characteristics, are increasingly widely used in modern high-speed, high-precision rolling mills.

Jingcheng Technology has been deeply rooted in the industry for decades, focusing on the research and development and manufacturing of high-performance rolling mill rolling bearings. We deeply understand the special requirements of bearings under different rolling conditions and have specifically launched three series of products to comprehensively cover mainstream application needs.

Our four-row tapered roller bearings are the preferred solution for backup rolls in hot strip mills. Their optimized raceway design and internal clearance control effectively distribute complex loads, ensuring stable performance under high temperature and heavy load conditions. Four-row cylindrical roller bearings are known for their excellent radial load capacity, especially suitable for the precise guidance of work rolls in cold rolling mills, providing a solid guarantee for strip shape control. The self-aligning roller bearing series, with its self-aligning characteristics, can compensate for installation misalignment errors and plays an irreplaceable role in various auxiliary parts of rolling mills.

Every set of Jingcheng rolling mill bearings embodies our deep understanding of material science, heat treatment processes, and precision manufacturing technology. From the selection of special bearing steel to the precise control of multi-stage heat treatment, and then to nano-level precision grinding, we have built a full-process quality control system to ensure that every bearing can provide long-lasting service under demanding conditions.

Choosing professional rolling mill bearings means choosing a guarantee for continuous production. Jingcheng Technology not only provides products but also offers customers a full-cycle service solution including selection consultation, installation guidance, and condition monitoring. We believe that superior rolling mill bearings should be the "invisible yet robust force" within rolling mill equipment, silently protecting during every rolling process and imprinting precision quality on every inch of sheet metal.

Facing the future trend of high-efficiency and intelligent development in the rolling industry, Jingcheng Technology will continue to innovate, dedicating itself to providing global customers with more reliable and longer-lasting rolling mill bearing solutions, and working together with you to promote the improvement of fundamental capabilities in the manufacturing industry.
