Rotary seals are one of the product types that Ruichen Sealing, as a professional seal manufacturer, can provide you with different sealing materials and seals. We focus on the research and development and production of high-speed, high-pressure, and extreme-condition resistant rotary seals, serving wind turbine main shafts, pump and valve transmissions, food machinery, and aerospace fields. The company has passed the ISO 9001 international quality system certification, has more than 40 patented technologies, and has cooperated with Qingdao University of Science and Technology to establish a rotary seal test platform (supporting 5000rpm+ high-speed testing). With advanced CNC processing equipment and mold-free production technology, we provide high-precision and long-life rotary seals to global customers, with "zero leakage and low friction" as the core advantage, becoming the industry's technical benchmark.
Rotary seals include 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 products are used in Roots blowers, centrifuges, hydraulic pumps, air compressors, vacuum pumps, chemical pumps, etc.
