From July 17 to 20, 2025, APIE2025 Asia Pacific International Intelligent Equipment Expo and the 27th China Qingdao International Industrial Automation Technology and Equipment Exhibition will be held in Qingdao International Convention and Exhibition Center (Hongdao Pavilion)!
As a professional brand in the field of hydraulic seals, Qingdao Ruichen Sealing Technology Co., Ltd. will bring a full range of industrial sealing products and technical solutions to make a wonderful appearance. Focus on display: six major categories of products such as hydraulic seals, high-pressure seals, rotary seals, turning seals, pan-seals, and high-performance sealing materials.
Commonly used hydraulic seals include U-rings, Y-rings, V-rings, Step seals, Gley rings, guide and dustproof rings, O-rings, star rings, retaining rings, etc. Commonly used sealing materials include rubber, polyurethane, engineering plastics, etc., which are used in various hydraulic systems such as hydraulic cylinders, valves, accumulators, pumps and motors.
High-Pressure and Ultra-High-Pressure Seals
Containing a number of the latest national patent technologies, the independently developed high-pressure seals have the characteristics of high life, low friction, and excellent sealing. The maximum working pressure of the dynamic seal is 720MPa, which can be used for water pressure sealing. The product is used for hydraulic nuts, plunger pumps, isostatic presses, homogenizers, etc. It is the leader of high-pressure and ultra-high-pressure seals in China.
Contains a number of the latest national patent technologies, independently developed high-pressure and high-speed rotary seals. The maximum linear speed can reach 40m/s, of which the high-speed rotary seal has a pressure resistance of up to 3.5MPA, and the low-speed rotary seal has a pressure resistance of up to 100MPA. And oil-free lubrication can be achieved. The product is used for Roots blowers, centrifuges, hydraulic pumps, air compressors, vacuum pumps, chemical pumps, etc.
Ruichen Seals turning seals, with more than 260 pre-stored cross-sectional types, can quickly produce rubber, polyurethane, and engineering plastic seals of any specifications and cross-sections. No mold is required, and the fastest delivery is 1 hour. The maximum processing diameter of the turning seal is 2600mm.
It is made of a PTFE sealing ring with a stainless steel spring embedded in it. It is a high-performance seal developed for high temperature, corrosion, poor lubrication, low friction and other application environments to meet the increasingly demanding and diverse needs of industrial applications. Such as food and drug machinery, petrochemical equipment, pumps and valves, pressure vessels, aerospace equipment, etc.
High-Performance Sealing Materials
Various modified PTFE composite materials; various polyurethanes, rubber tubes and rods; nylon, polyoxymethylene, ultra-high molecular weight polyethylene, polyetheretherketone and other engineering plastics. It is the basic material for turning seals and can replace imported similar products.
Whether you are an equipment manufacturer, a person in charge of technical procurement, a terminal equipment user or an industrial automation practitioner, you are welcome to visit the Ruichen booth to discuss the forefront of sealing technology with us and talk about new trends in the industry!
