Company Profile

"Hebei Jiuyuan Sealing Technology Co., Ltd. was founded in 1988, specializing in the production of hydraulic cylinder seals. It is a comprehensive strength enterprise integrating development, production, sales and services. It passed ISO quality system certification in 2002 and obtained the (National Industrial Product Production License) products are widely used in electromechanical industries such as metallurgy, mining, electric power, automobiles, engineering machinery, light industry, chemical industry, water conservancy, etc., and have done a lot of work for the introduction of localization of electromechanical equipment seals in China. Gain the trust of our customers.



Our company has a high-quality R&D, production, and sales service team. With decades of accumulated experience, we can independently develop, design, and produce various types of hydraulic cylinder seals, sealing rings, U-rings, and Y-rings. , V-shaped, special-shaped parts, oil seals, mining seals, Grain rings, guide belts, special seals, dust rings, etc., and work closely with customers according to the different operating conditions of the cylinder to provide mature and high-quality sealing solutions . The company uses CNC machine tools, fully automatic injection molding machines, vacuum flat plate vulcanizers, imported moldless turning machine tools and other advanced production equipment to improve production efficiency and the inherent quality of products. It has invested a lot of resources to establish a seal performance laboratory and has advanced inspection , testing equipment, everything from raw materials to product performance can be controlled through experimental data. The actual use conditions of the oil cylinder are simulated through the oil cylinder test bench to conduct product performance tests. The process is constantly updated and product formulas are optimized so that the products can meet the sealing requirements of different hydraulic fields.

The product involves a construction machinery factory. The XCMG Group's bench life test proved that: the reciprocating stroke is 520km, the reversal is 400,000 times, the operation is normal and there is no leakage, and the sealing effect reaches the standards of similar foreign products. It has become the XCMG Group, Beiqi Foton, Shantui, China Heavy Long-term partners of large enterprises such as Steam, Yuye Group, and China Coal Group. Keeping pace with the times and forging ahead in scientific and technological innovation is our company's development policy to become a pioneer in the industry.



The company adheres to the corporate purpose of "earning trust with product quality and taking honest cooperation as the basic concept" to provide customers with high-quality sealing products and thoughtful and timely after-sales services. "
