SKF Magnetic Bearings: Revolutionizing Industrial Machinery
SKF Magnetic Bearings: Revolutionizing Industrial Machinery
Magnetic bearings, a groundbreaking technology developed by SKF, have revolutionized the world of industrial machinery. Unlike conventional bearings that rely on physical contact, magnetic bearings levitate rotating shafts using electromagnetic forces, eliminating friction and wear. This innovative technology offers numerous advantages, making it an essential solution for various industries.
How Do Magnetic Bearings Work?
SKF magnetic bearings utilize electromagnetic principles to generate levitating forces. A series of electromagnets, strategically positioned around the rotating shaft, create a magnetic field that counteract the gravitational pull and centrifugal forces acting on the shaft. By actively controlling the current flowing through the electromagnets, the magnetic field adjusts to maintain the shaft perfectly centered, ensuring smooth, frictionless rotation.
