Definition
Contactless bearing, in which the shaft is held in position by magnetic forces in the axial and radial directions (CIRP Dictionary of Production Engineering 2004).
Theory and Application
Basic Working Principles
The idea of suspending an object with magnetism was first conceived in the mid-1800s. For a long time, considered complex, costly, and commercially ineffective, magnetically levitated bearings have lately proven their effectiveness, reliability, and competitiveness in industry, where the number of their applications is rapidly growing. Magnetic bearings show a number of important advantages over conventional bearing technologies, such as lubricant- and contamination-free operation, suitability for high-speed and high-performance applications, and inherently built-in instrumentation facilities for system monitoring. This development has, in parallel, also called for a...
