Magnetic Fluid Dust Seal "Exclusion Seal"
Perfect for semiconductors, LCDs, and clean environments! Magnetic fluid dust seal with perfect sealing effect.
The basic principle of the "Exclusion Seal" consists of a unit that forms a magnetic circuit, made up of permanent magnets, with N and S poles, and ball pieces for the two magnetic poles. By passing a magnetic shaft through this magnetic circuit unit, the magnetic flux concentrates in the radial gap between the shaft and the ball pieces. When a magnetic fluid is filled in that gap, a liquid O-ring seal is formed. Applying this technology, it is now used not only in OA and FA equipment but also in various robotic transport systems in clean rooms. The perfect sealing effect has achieved an ultra-clean environment. 【What is a magnetic fluid?】 - A magnetic fluid is a colloidal liquid in which magnetic nanoparticles of about 10 nanometers are dispersed in a liquid. - Even in the presence of an external magnetic field, there is no separation or aggregation of the particles and the base liquid. *For more details, please refer to the catalog or feel free to contact us.
