Bearing of high-precision rolling mill series of bearing bush has reached grade P5

recently, the multi specification high-precision rolling mill series bearings processed by the bearing bush transmission company for an iron and steel metallurgical enterprise are being produced in succession, and the accuracy has reached grade P5, meeting the special requirements of customers for structure and so on. The customer has put forward a total of four specifications of new products, which are mainly used in H-beam and high-speed wire rod mills. Structure

recently, the multi specification high-precision rolling mill series bearings processed by the bearing company for an iron and steel metallurgical enterprise are being produced in succession, and the accuracy has reached P5 level, meeting the special requirements of the customer for structure and so on

the customer has put forward four new product requirements in total, which are mainly applied to H-beam and high-speed wire rod mill. The structure is specially customized, and the bearing width is twice that of conventional products, which makes it more difficult to turn the zigzag rod in process design. In particular, for the inner diameter and raceway processes, the width and height that are too wide have far exceeded the grinding range of ordinary grinding machines. Therefore, the company has adopted special processing methods and customized special fulcrum to ensure that the raceway contour shape meets the design requirements, and the bearing inner diameter taper, perpendicularity and other rotation accuracy indicators have reached the P5 level requirements. "With years of processing experience and advanced equipment, the parallelism of bearing end face is controlled at 0.005mm, and the dimension dispersion is controlled at 0.0. The main cost lies in the service life of 5mm, which lays a good foundation for the processing, positioning and inspection of subsequent processes without experiments for a long time. At the same time, it also provides customers with a more accurate installation and positioning benchmark." Wang Feng, director of the engineering department in charge of technical quality of the bearing company, said

the order quantity of this batch of products is over 100 sets, the delivery time is short, and the production cycle is very tight. "Our steel series bearings account for a large proportion this month, which has brought great inconvenience to people. This batch of products is the focus of production. We work together to catch up with them." Yuzhonglong, deputy director of the logistics department in charge of order scheduling, said that at the end of September, the company rushed out a batch of urgently needed bearings for customers, and the rest of the products will be delivered in the near future
