Magnetic  Bearing

          A magnetic bearing is a type of bearing that uses a magnetic force to support machinery parts without having any actual contact with the part itself while the machine is turned on. The magnetic force is strong enough that it lifts the small piece of the machine and allows it to move while it is suspended in the air. This eliminates the friction between the piece and the machine itself.

          SKF is a leading global supplier of engineered products, customer solutions and services to the industrial and automotive marketplaces. Our solutions vary from high value-added mechatronics systems that simplify motion and process control, to the right bearing or seal that meets the demands of a specific application. SKF also offers sophisticated simulated design and virtual testing competencies that yield better products and improved productivity for our customers. SKF was founded in 1907, and from the very beginning focused intensively on quality, technical development and marketing. The result of our efforts in research and development has been a continuously growing number of innovations that have created new standards and new products in the bearing world. Glo bally, SKF has over 80 manufacturing sites, and sales companies in 70 countries supported by more than 10,000 distributors and dealers.

          SKF Magnetic Bearings has supplied thrust bearings from 130 to 24,500 N (30 to 5,500 lbf), for shaft diameters ranging from 9 to 130 mm (3/8 to 5 inches). These are installed on machines that have rotational speeds ranging from 1,800 to 100,000 rpm. SKF also supplies canned thrust bearing designs for hermetically sealed applications and thrust bearings for high temperature applications up to 220°C (428°F).The thrust bearings shown above are 17,000 N capacity (3,800 lbf) for a 12,000 rpm turbocompressor with a 120 mm shaft.
