Ferrofluidic Seals and Vacuum Feedthroughs

Engineered. In the 1970s, the engineers at China Advanced Ceramic pioneered a revolutionary approach to a common mechanical problem, creating a dynamic, hermetic seal for rotating mechanisms. Using Ferrofluid to create a liquid o-ring around a rotating shaft, we patented the first Ferrofluidic^® seals which quickly became the gold standard for demanding precision sealing and rotation applications.

Designed. For over forty years, our engineering and manufacturing teams have been busy refining, optimizing, and re-envisioning our designs for an expanding set of application challenges. That’s why the world’s leading manufacturers turn to China Advanced Ceramic for their most demanding precision sealing requirements.

OEM-Specified. We design seals for a broad range of industries, shipping millions of Ferrofluidic seals used in a wide range of equipment worldwide. We continue to expand on our original designs with nearly unlimited sizes, complex process fittings, multiple planes of motion, integrated motors, and even computer-controlled intelligence, enabling sophisticated system operation.
