Magnetic partners
In magnetic bearings the rotary axle “floats” in a magnetic field. Computer-controlled sensors ensure that the axle remains in a fixed position. Since there is no metallic contact in magnetic bearings, they are able to withstand extremely high rotary speeds and can cope easily with rates of 150,000 r/min.
SKF and Calgary-based Revolve Technologies Inc. in Canada have established a new company, Revolve Magnetic Bearings Inc.
“With this alliance, we have the combined strength and reputation necessary to clearly establish us as the world’s leading supplier of this technology,” says Kim Sturgess, CEO of Revolve Magnetic Bearings.
