Product
Product category:Hydraulic drive, control and process control engineering
Common hydraulic seals include U-cups, Y-rings, V-packings, Step seals and Glyd rings, guide rings and wipers, O-rings, X-rings, and backup rings. Widely used sealing materials encompass elastomers, polyurethane, and engineered plastics, deployed across hydraulic cylinders, valves, accumulators, pumps, and motors.
Product category:Hydraulic drive, control and process control engineering
Engineered with multiple patented innovations, our proprietary high-pressure rotary seals deliver breakthrough performance: maximum surface speed of 40 m/s, featuring 3.5 MPa pressure rating for high-speed variants and 100 MPa capability for low-speed applications. Designed for oil-free operation, these seals are deployed in Roots blowers, centrifuges, hydraulic pumps/motors, air compressors, vacuum pumps, and corrosion-resistant chemical pumps.
Product category:Hydraulic drive, control and process control engineering
Engineered with multiple patented technologies, our proprietary high-pressure seals deliver exceptional longevity, ultra-low friction, and superior sealing integrity. Dynamic seals withstand operating pressures up to 720 MPa with hydrostatic sealing capabilities. Deployed in hydraulic nuts, plunger pumps, isostatic presses, homogenizers, and intensifier systems, we stand as China's premier manufacturer of ultra-high-pressure sealing solutions.
Product category:Hydraulic drive, control and process control engineering
Ruichen Seals machined seals pre-stock over 260 cross-section profiles. Rapid production of any size/profile in rubber, polyurethane, engineering plastics. Without molds, 1-hour delivery fastest. Max. machining diameter: 2600 mm.
Product category:Hydraulic drive, control and process control engineering
A PTFE sealing ring encapsulating a stainless steel spring core, engineered for demanding applications involving high temperature, corrosion, poor lubrication, and low friction requirements. This high-performance seal addresses increasingly diverse industrial demands across food/pharmaceutical machinery, petrochemical equipment, pumps/valves, pressure vessels, and aerospace systems.
