Patent number: 11067129Abstract: A rolling bearing having an inner raceway and an outer raceway and a plurality of rolling elements arranged therebetween. The rolling bearing is media-lubricated or oil-free lubricated. The lubricant forms an elasto-hydrodynamic lubricant film between the rolling elements and the raceways. At first use of the rolling bearing, at least one surface of the rolling bearing is coated with a protective fluid, preferably an oil-based preservative fluid. Also, a refrigerant compressor having such a rolling bearing.Type: GrantFiled: September 18, 2019Date of Patent: July 20, 2021Assignee: Aktiebolaget SKFInventors: Hans Wallin, Rudolf Hauleitner, Guillermo Enrique Morales Espejel
