Shanghai Mingyuante Electromechanical Equipment Co., Ltd.

Shanghai Mingyuante Electromechanical Equipment Co., Ltd. is located in Shanghai, China, with superior geographical location and convenient transportation. Linqing Bearing Production, Liaocheng City, Shandong Province has its own bearing processing factory. It is a bearing manufacturer specializing in trade processing and production, and integrating domestic and foreign trade. The price advantage. Has an excellent team composed of professional and engineer staff.

The company specializes in trading all kinds of bearings; Single row deep groove ball bearings, outer spherical bearings, tapered roller bearings, diameters from 12 to 360mm, electronic products, auto parts wholesale, including metric and inch bearings. Production will be according to your requirements and samples.

We adhere to the principle of "high quality and low price, first-class service, honesty and common development", and cooperation with foreign customers. As a bearing manufacturer integrating sales, we adhere to the business philosophy of "quality first, service first, continuous improvement, innovation to satisfy customers", and take "zero defect, zero complaint" as the quality goal. Most bearing rings and rolling elements are made of special steel. The rings and rolling elements are made of high carbon chromium bearing steel (GCr15 and GCr15SiMn and ZGCr15 and ZGCr15SiMn), and the hardness of the parts is as follows:

The rings and rollers made of GCr15 and ZGCr15 are HRC61~65, and the steel balls are HRC62~66;

The rings and rollers made of GCr15SiMn and ZGCr15SiMn materials are HRC60~64, and the steel balls are HRC60~66.

Bearings made of high carbon steel chromium bearing steel are generally suitable for working temperatures of -40 to 130 degrees, and oil and grease lubrication is normal. It can meet the requirements of general machinery.

After high-carbon chromium bearing steel bearing parts are tempered at high temperature, the working temperature can be as high as 250 degrees.

With the advancement of smelting technology, different smelting methods can be used for high carbon chromium bearing steel, such as vacuum smelting technology, which can greatly change the inherent quality of the steel, especially the oxygen content in the steel and its non-metallic inclusions. Significantly reduced. The fatigue life of bearings made with this high carbon chromium bearing steel can be doubled.

According to a large number of experimental comparison data, GCr15, GCr15SiMn, ZGCr15, ZGCr15SiMn bearing steel obtained by different smelting methods are used to manufacture bearings. The company is equipped with modern production equipment and advanced testing instruments, including deep groove ball bearings, tapered roller bearings, spherical roller bearings, cylindrical roller bearings, wheel bearing units, to replace imported high-end products. Bearings have P0, P6, P5 or P4 precision and are widely used in complete sets of products in metallurgy, mining, petroleum, chemical, coal, cement, paper, wind power, heavy machinery, construction machinery, port machinery and other industries...Have self-support import and export rights, learn from foreign advanced bearing companies, and constantly strive to create high-quality bearings made in China. With the mission of revitalizing the national industry, the company injects vitality into the local economy and promotes the harmonious development of the company, society and nature. The company adheres to the business philosophy of "diligent development, sincere service, meticulous manufacturing, and brand strategy", and cooperates with domestic and foreign customers on the principle of honesty and fairness. The company takes meticulous quality control measures to improve products and services to provide high-quality products and services to customers around the world.
