2. Babbitt (alloy) - Wikipedia

   en.wikipedia.org/wiki/Babbitt_(alloy)

   Babbitt metal or bearing metal is any of several alloys used for the bearing surface in a plain bearing. The original Babbitt alloy was invented in 1839 by Isaac Babbitt [1] in Taunton, Massachusetts, United States. He disclosed one of his alloy recipes but kept others as trade secrets. [2] Other formulations were developed later. [3]

3. Ferrofluidic seal - Wikipedia

   en.wikipedia.org/wiki/Ferrofluidic_seal

   The ball bearings provide two functions: maintaining the shaft's centering within the seal gap and supporting external loads. The bearings are the only mechanical wear items, as the dynamic seal is formed with a series of rings of ultra-low vapor pressure, oil-based liquid, held magnetically between the rotor and stator. As the ferrofluid ...

4. Magnetic levitation - Wikipedia

   en.wikipedia.org/wiki/Magnetic_levitation

   Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used. Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces. [2]

5. Magnetic bearing - Wikipedia

   en.wikipedia.org/wiki/Magnetic_bearing

   A magnetic bearing. A magnetic bearing is a type of bearing that supports a load using magnetic levitation. Magnetic bearings support moving parts without physical contact. For instance, they are able to levitate a rotating shaft and permit relative motion with very low friction and no mechanical wear. Magnetic bearings support the highest ...

6. Magnetic alloy - Wikipedia

   en.wikipedia.org/wiki/Magnetic_alloy

   A magnetic alloy is a combination of various metals from the periodic table such as ferrite that exhibits magnetic properties such as ferromagnetism. Typically the alloy contains one of the three main magnetic elements (which appear on the Bethe-Slater curve ): iron (Fe) , nickel (Ni) , or cobalt (Co) .
