Company Overview

Dalian HuaYang JingGong Bearing Manufacturing Co.,ltd.

Who is Dalian Huayang Jinggong Bearing Manufacture Co.,Ltd.?

Dalian Huayang Jinggong Bearing Manufacturing Co. Ltd. is a modern high-tech enterprise located in Wafangdian, China - also known as the bearing capital of the country. Established in 2004, the company specializes in technical research, manufacturing, and service of bearings. With years of relentless effort and commitment to quality, we have become a large-scale bearing manufacturer with an annual production value in the millions of RMB. Our registered trademark is HYJG.

After a decade of continuous improvement, we have incorporated the best qualities of famous brands to develop our own HYJG brand. Our range of products includes four-row cylindrical roller bearings for rolling mills, high-speed, low-noise, low-vibration single-row cylindrical roller bearings for motors, and long-life, high-speed tapered rollers and plain bearings for the metallurgical industry. Our products come in sizes ranging from 120mm to 1600mm in inner diameter, with an accuracy class reaching P4, vibration value exceeding Z2, and noise level exceeding V2.

How Do We Ensure Precision and Quality?

At Dalian Huayang Jinggong Bearing Manufacturing Co. Ltd., we are committed to providing the best quality products and services to our customers. Our team of experts is dedicated to continuous innovation and development to ensure that we remain at the forefront of the industry. Contact us today to learn more about our products and how we can help you with your bearing needs.

The company has established a quality control center and has introduced high-precision measuring equipment such as two German contour instruments, a surface roughness measuring instrument, a French carbon fiber measuring ruler, magnaflux, an ultrasonic flaw-detecting machine, a metallographic microscope, and a one-meter length measuring machine. These tools allow us to identify each batch of products and establish records of product information that includes the supplier of the raw materials, the related main technical index, and actual observation records during the production process.

We have also introduced 33 leading CNC machines and 7 raceway super-finishing machines, including five 4-axis linkage machines. The dimension discreteness can be controlled under 0.005m, and the accuracy class can reach P4, allowing us to produce logarithmic curves of raceways and convexity in ribs. We have also applied a grinding control system to prevent burning in our CNC machines, which can double bearing life by reducing the deteriorated layer and increasing Ra to 0.04um, reducing friction through super-finishing.

Overall, these advanced technologies and quality control measures allow us to produce high-quality products with precision and accuracy, ensuring customer satisfaction and long-term success in the industry.

How is HYJG Bearing Production?

Dalian Huayang Jinggong Bearing Manufacturing Co., Ltd has had its own nitrogen protection bath bainite heat treatment production line since 2008. Nitrogen protection is used to eliminate the decarburized layer, and a special heat treatment is utilized to make the bearing structure more stable, achieving an HRC level within a variance of plus or minus one degree.

In order to improve the heat treatment quality of products, the company introduced a nitrogen protected salt bath bainite quenching continuous production line in 2008! Nitrogen protection is used to reduce decarburization layer and salt bath quenching, which can make the heat treatment structure of the workpiece more stable, and the hardness can reach HRC plus or minus 1 degree.
