Abstract

Rolling bearings and methods of making the same are disclosed. The rolling bearing may include an inner ring, an outer ring and rolling elements arranged radially or axially between the inner ring and the outer ring. A coating may be formed at least partially on the inner ring, and/or on the outer ring, and/or on the rolling elements, wherein the coating is formed predominantly from tungsten and is configured to prevent white etching cracks. The rolling bearing may be used in a wind turbine.
