CAT No.N004E-11000Magnetic Fluid Seal1Typical con figurations Multi-axial (two or three shafts) Reciprocating (bellows seal)PressurizedThe NOK group produces the full range of vacuum seal components including O-rings,bellows, bearing lubrication grease and magnetic fluids (see diagram).This enables us to tailor our products to the precise design requirements of individual clients.Welded metal bellows (Eagle Industry)NOK NOK CORPORATION NKL NOK KLÜBER CO.,LTDDesign specifications tailored to client requirements2Magnetic fluid seals from Eagle Industry are employed in a wide range of industrial applications includingmanufacturing (typically semiconductors, LCD panels, solar panels and LED devices) as well as industrial machinery, analyzers and clean robots. Our high-performance and high-reliability seals have been adopted throughout the world.Uses of the magnetic fluid sealEssentially, magnetic fluid is a liquid that is attracted to magnets—in other words, a magnetized liquid.Magnetic fluid consists of three components:(1) magnetic particles, (2) surfactant and (3) a base liquid.The performance of a magnetic fluid seal is largely dependent on the properties of the magnetic fluid.Without surfactant, the very small magnetite (Fe 3O 4) particles (approximately 0.01μm) tend to separate and settle and do not remain evenly mixed with the base liquid. The surfactant envelops the magnetic particles and causes them to oppose one another within the base liquid. This prevents settlement and maintains a uniform distribution of particles (see diagram below).Eagle Industry boasts an extensive understanding of the many parameters of magnetic fluids including particle size, surfactant structure, molecular weight and particle absorption, base liquid purity, surfactant compatibility and dispersion characteristics. These parameters are carefully tailored to produce optimized magnetic fluids for different applications.Base liquids are designed and manufactured within the NOK group.One of the major strengths of Eagle Industry magnetic fluids is that all of the constituent components are designed and manufactured within the NOK group. Our products offers superior high-temperature durability, corrosion resistance, plasma resistance and very low-temperature outgassing performance compared to competitors' products.Magnetic fluid seals from Eagle Industry utilize magnetic fluids that have passed a stringent final qualitytesting process prior to delivery.SpikingWhen a magnet is brought close to magnetic fluid, the magnetic fluid attempts to orient itself with the magnetic force lines. This actsin opposition to interfacial tension, resulting in the phenomenon known asspiking (see photograph).3What is magnetic fluid?4Magnetic fluid selection table* Eagle Industry will be happy to recommend the best process setup and magnetic fluid for your particular operating environment and objectives.

The sealing action is provided by a sealing skin called the liquid O ring that is formed by the magnetic fluid.Magnetic fluid seals have superior longevity to solid seals as well as lower torque due to the absence of abrasion. However they are not suitable for use with liquids such as water.A magnetic fluid vacuum seal is a special type of magnetic fluid seal used to keep a vacuum.Magnetic fluid vacuum seals are used for delivering rotational power to vacuum chambers, typically in electronic manufacturing systems (such as semiconductors) and analysis equipment.Since pressure resistance of one atmosphere(101.3 kPa) cannot be achieved via a single stage, a multi-stage design is used. Where the pressure differential exceeds the resistance of a stage, gas passes through the magnetic fluid, which then repairs itself. As this process occurs at successive stages, the pressure is apportioned between the stages, creating an equilibrium that maintains theStart of evacuationInitial state Fluid5What is a magnetic fluid seal?About magnetic fluid vacuum sealsMagnetic fluid is a colloidal liquid consisting of nano-sized magnetic particles distributed through a liquid body. As the name suggests, magnetic fluid is attracted to magnetic bodies.Magnetic fluid was originally developed in 1965 by S. S. Papell from NASA (National Aeronautics and Space Administration) as a rocket fuel propulsion technology for weightless environments(1). Subsequent modifications and enhancements have seen magnetic fluids adopted in a wide range of applications from the everyday to the cutting-edge.A magnetic fluid seal is a type of seal that utilizes magnetic fluid.Dust seals and vacuum (or hydraulic) seals generate minimal levels of dust, friction and contamination and provide excellent heat and plasma resistance. As such, they are extensively used in clean production environments, typically for manufacturing semiconductors, LCD panels, solar panels and LED components.19841988 1990 19961999 2002 2009NOK Corporation launches research on in-house production of magnetic fluid products.Commences production and distribution of dust seals.Commences production and distribution of vacuum seals.Develops magnetic fluid 3551 featuring low vapor pressure and high heat resistance.

A dust seal consists of a magnet, two pole pieces and a shaft, which form a magnetic circuit that holds magnetic fluid in the gaps between the shaftand the pole pieces.Fluid* Dimensions subject to change without notice.Dust seal10Quantity: 500μ3Scale increments: 5μ3Needle (outer x inner diameter):ø0.71×ø0.41mmNeedle length: 51mml Use and handling of dust seals[Option] Magnetic fluid syringe1. Dust seals and magnetic fluids should be stored in a cool location with low humidity and not in direct sunlight.2. Do not mix magnetic fluid with other liquids.3. Take care to avoid oil, grease and magnetic particle spills during use.4. Use a suitable solvent to remove any grease or oil on the shaft surface.5. Attach dust seals to housing using O-rings or adhesive to ensure a secure fit and a good seal.6. Extract magnetic fluid from the container using the magnetic fluid syringe (optional).Take care to prevent air from entering the syringe.Air can affect measurement accuracy, which in turn can compromise the performance of the dust seal. If the magnetic fluid does not draw easily into the syringe, try warming the container first.7. Apply magnetic fluid to the gaps between the shaft and the dust seal (or pole pieces).The correct quantities are indicated on the delivery drawings.8. Use a suitable solvent to clean the syringe.The magnetic fluid syringe (optional extra) provides a clean, easy, accurate and ef ficient means of applying the magnetic fluid.Rotating shaft seals based on the O-ring + vacuum grease design have a relativelyshort maintenance cycle, in the range of several weeks to a few months. Vac Guard ®was developed in response to industry calls for seals with similar performance but alonger life expectancy.The seal is formed with special shaped elastomer, using magnetic fluid as lubricant.The magnetic fluid is the same as that used in magnetic fluid vacuum seals, and hasbeen extensively used in vacuum environments already.Life expectancy: longer than O-ring seal Reduces preventative maintenance (extends MTBF) andcost of ownership.Low-dust design: generates less than 0.05% as muchdust as an O-ring seal (0.1 μm and larger)Low driving torque: 50% lower than O-ring sealFeatures11Vac Guard ®PATENT PENDINGShaft Special shaped elastomer Magnetic Fluid12Test conditions: 25, speed = 300 rpm, vacuum pressure = E-4PaRotation regime: CW for 2 min. rest for 5 sec CCW for 2 min. repeatedTable of dimensions (for reference)Comparison PropertiesNecessary 131.Solvents or other fluids (such as acetone,alcohol, water and oils) or contaminants (such as solids and dust particles) inside a magnetic fluid seal can impact on performance. Take care to protect the seals from contamination. To clean the exterior of the seal, use a clean room wiper impregnated with a small quantity of ethyl alcohol. Note that too much ethyl alcohol on the wiper can cause drips, which could contaminate the seal and affect performance. 2.Leak testing should be performed using an Heleak tester. Never use alcohol or solvents for leak tests. Solvents can contaminate the seal and affect performance.3.Do not exceed the rated pressure (98 kPafor vacuum seals, or for pressurized seals, the maximum pressure stated on the delivery specifications or delivery drawings).4.Magnetic fluid seals designed for inert gasesshould not be used with reactive gases.Reactive gases may affect performance and/ or cause damage to structural components.Similarly, seals designed for use with reactive gases should only be used with the gases listed on the delivery specifications or delivery drawings. Non-listed gases may have an adverse effect on magnetic fluid and sealing performance.5.Magnetic fluid seals must not be subjected toshock, such as being dropped or struck witha hammer, since sudden shock can causedamage to the internal bearings and structural components. If a seal is dropped, check carefully for signs of damage. A damaged seal should be replaced immediately. Remember that internal damage and deformation may not be externally visible.6.When attaching a seal to equipment, centerthe seal first and use a coupling mechanism to connect it. When a seal is poorly centered, load imbalance may affect performance.7.Water-cooled seals should be cooled using 1- 3 liters per minute of ordinary mains water or equivalent coolant at normal temperature, taking care to avoid condensation. Condensation on the seal can affect performance and prevent normal rotation.8.Keep seals away from magnets and magnetizeddevices such as speakers, since magnetism can affect sealing performance.9.When using a vacuum seal for the first time,or when generating a vacuum after a long period of non-use, there may be a slight initial increase in pressure. Also, starting torque and loss torque tends to increase with the length of time that the seal is unused or in storage. These phenomena are associated with partial pressure balance and segmentation of magnetic fluid. For best results, the seal should be acclimatized with at least 20 rotations prior to generating a vacuum.10.Where the chamber of a reactive gasvacuum seal is released to the environment,a cycle purge with N2 gas is recommendedin order to improve the consistency of sealing performance.11.Seals should not be stored in locations thatare humid, dusty, or subject to extremes of temperature. Ideally, seals should be kept in a clean room or other environment with temperature and humidity control. Do not open the vacuum packaging until ready to install the seal.Operating instructions1.Do not touch the product while in operation.2.Where a vacuum seal is suspected of causingabnormal pressure, stop the equipment and perform an He leak test. If the vacuum seal is found to be faulty, remove and replace immediately.3.In the event of bad rotation, stop the equipmentand turn the shaft by hand. If the rotation is found to be faulty, replace the seal.4.If the seal is dropped or otherwise subjectedto a strong external force, stop the device immediately and perform a leak test. Also turn the shaft by hand. If rotation is found to be faulty, replace the seal.Usage and handling tipsUsage and handling tips for magnetic fluid seals14。
