Ruichen is at the forefront of the innovation of sealing technology. The independently developed high-pressure dust seals precisely anchor the dust-proof demands of moving parts, and use PTFE dust rings and O-rings to create excellent protection. When working, the O-ring applies a stable preload to compensate for the wear of the PTFE ring at all times, ensuring long-term stability of the seal; the dust ring uses anti-wear filling materials to strongly resist dust invasion. For example, in the joints of the hydraulic cylinders of construction machinery, facing the dust on the construction site, high-pressure dust seals effectively block dust intrusion and ensure smooth operation of the cylinder; the reciprocating swing link of the robotic arm of the automated production line, its dust seals protect precision parts from dust interference and maintain high-precision operations; and the spiral conveying device of the mining equipment, in the environment of ore dust, high-pressure dust seals ensure stable operation of the equipment, reduce potential faults, and extend the life of the equipment. Ruichen Sealing has been focusing on in-depth development for a long time. Relying on a professional team and cutting-edge facilities, it can not only customize high-performance sealing materials according to customer needs and independently control production quality, but also reserve rich and diverse materials such as polyoxymethylene, helping customers to overcome various sealing problems in one stop and work together to reach new heights in the industry.
