Auto Vacuum Parts Vacuum Parts Bearings components/Vacuum Parts Ferrofluid sealed gearing is a product based on the ferrofluidics technology. When ferrofluid is injected into a gap in the presence of magnetic field, it can form a liquid barrier. The ferrofluid sealed gearing just takes advantage of the principle to build a liquid seal ring wherever required, to gain the effect of sealing. It may introduce rotatory motion into being used in the vacuum chamber or operating field with a differential pressure. Nowadays, the gearing has been widely applied to many fields including semi-conductor manufacture, liquid crystal manufacture, etc. and it has been a preferred sealing way.Sealing characteristic: 1.Implementation of a clean and high vacuum environment 2.Wide rotation speed limit form low speed to high speed 3.Operation with no abrasion and long lift 4.Application in various environments with high pressure, high temperature and corrosive gas. 5.Design various shapes of the ferrofluid according to customer' needsProduct catalogue: Shaft type: Solid Shaft(S), Hollow Shaft(K), Multiaxial Shaft(D) Housing type: Flange type(F), Bolt type(S), Nut type(M), Through hole type(T) Cooling Way: No Water Cooling(W), Water Cooling(F)
