Super Large Integral Bearing Forgings Rolled Off The Production Line at IRAETA


Recently, the super-large integral bearing forgings with a diameter of 11.5 meters provided by IRAETA have successfully rolled off the production line, and have passed the certification and customers acceptance of CCS. This forging set a new record for the world's super-large integral bearing forgings.

With continuous breakthroughs in manufacturing technology of China, equipment accessories are developing in the direction of large-scale and high-end. Moreover, bearings are mechanical products and are improtant basic parts. Therefore, in addition to dimensional accuracy, factors affecting bearing performance are the materials and processing techniques used in the production process of the body.

In the past, such large-scale bearing forgings mostly used segmented welding, which not only had a long processing cycle and high cost, but also had weak material structure and performance at the weld position. This time, the bearing forgings provided by IRAETA to customers adopt the integral rolling process. On the one hand, it can make its internal structure more dense and streamlined more complete, and it can also make full use of the performance potential of metal materials, thereby effectively improving the service life and mechanical properties of the workpiece; on the other hand, it can greatly shorten the delivery time and effectively assist customers to achieve early production.

Currently, IRAETA continues to deepen cooperation with scientific research institutions, and is committed to promoting the development and application of various advanced technologies and materials. Cao Xuzhong, Executive President of IRAETA, said: The off-line of the bearing forgings fills the domestic gap in this field and increases the space for designers to think about.
