Jining Jingyi Bearing Co., Ltd

Jining Jingyi Bearing Co., Ltd. is a state-owned enterprise, Shandong Jining bearing factory reformed into a state-owned joint-stock enterprise. It was established in 1970 and is a professional needle bearing manufacturer of the former Ministry of mechanical and electrical engineering. The company covers an area of more than 50000 square meters, with more than 380 employees, 40% of whom are middle and senior technicians. Is specialized in the production of needle bearings and precision cylindrical roller bearings of China's "artisan" enterprises. The company has formed a business philosophy of "market-oriented, business-oriented, comprehensive production, technology and quality promotion". The management and control mechanism of the enterprise with simple and efficient, clear functions, clear objectives and quick response has been established, and the operation and management mode with the characteristics of lean bearing has been established and formed. The company mainly produces needle bearing, precision cylindrical roller bearing, thrust bearing, combined bearing, non-standard bearing, bearing race, etc., with more than 1800 specifications and an annual output of 25 million sets. Based on the advantages of "specialized, refined, special, new and excellent" enterprises, the products are designed and produced with international advanced technology and standards, with first-class domestic production equipment and advanced and complete imported and domestic precision testing equipment. The product quality is stable and reliable, ranking the advanced level in China, and some products replace the import.

National standard for bearings

The standard was established earlier. The quality grade of bearing can be determined by measuring the vibration acceleration value when the bearing rotates. It can be divided into three quality grades: Z1, Z2 and Z3 from low to high. At present, the domestic bearing manufacturers are still using the vibration acceleration value to measure the quality of the bearing, which simply reflects the fatigue life of the bearingwhich simply reflects the fatigue life of the bearingwhich simply reflects the fatigue life of the bearingwhich simply reflects the fatigue life of the bearingwhich simply reflects the fatigue life of the bearingwhich simply reflects the fatigue life of the bearing1

Publicity on the cooperation of Bote precision suppliers in 2020

Ordinary bearing rings and rolling elements are made of high carbon chromium bearing steel or carburized steel. The data used for the frame mainly include: the surface roughness of stamping steel, nylon, brass and other processing is determined according to the bearing accuracy and bearing size. The higher the accuracy is, the smaller the surface roughness is, the larger the straight diameter is, and the greater the surface roughness is. As for the fine and ordinary, they are returned separately
