Located in the Wafangdian, the bearing capital city of China, Dalian Huayang Jinggong Bearing Manufacturing Co. Ltd. was established in 2004. It is a modernized high-tech enterprise, incorporating technical research, manufacturing and service. It has become a large-scale bearing company with the yearly production of hundreds of millions of RMB after all these years of unremitting efforts, with the registered trademark being HYJG.
During which we learn after 10 years unremitting effort, incorporating all the good qualities of the famous brands and we developed our HYJG brand four row cylindrical roller bearings specialized for rolling mills, the high-speed, low-noise, low-vibration single row cylindrical roller bearings specialized for motor, the long-life, high-speed tapered rollers and plain bearings for Metallurgical industry. The size ranges from the inner diameter being 120mm to the outside diameter being 1600mm, the accuracy class reaching P4, the vibration value is over Z2, the noise level is over V2.
Testing Center
The company has set up the QC center, introduced high precision measuring equipments like two pcs German contour instrument and surface roughness measuring instrument, French Carbon fiber measuring ruler, magnaflux, ultrasonic flaw-detecting machine, metallographic microscope and one-meter length measuring machine to identify each batch products, and establish records of product information so that it is easy to read the supplier of the raw materials, and the related main technical index and the actual observation records during the process of production of each product.
The company introduced 33 leading CNC machines and 7 raceways super finishing machines, among which five of them are 4 axis linkage,the dimension discreteness can be controlled under 0.005m, the accuracy class can reach P4 so that it is able to produce logarithmic curve of raceways and convexity in ribs. In our CNC machines, we specially applied grinding control system to prevent burning. Bearing life can increase double because we can reduce deteriorated layer and increased Ra to 0.04um.,reducing friction by super finishing.
