Subject field(s)
  • Conductivity and Superconductivity (Electricity)
CONT

Contact bearings will benefit from ever-tighter tolerances and more rugged materials. A revolutionary non-contact bearing, the electromagentic bearing, repulsively or attractively levitates moving parts in a magnetic or electric field, with zero friction; wear can often be practically eliminated by having such a bearing gently "land" apart after it stops moving. The new high-temperature superconductors will make such bearings smaller, stronger, and more precise; since they are often computer-controlled, nanocomputers will be helpful too.
