Antifriction bearing unit i.e. safety bearing unit, for use in magnetic bearing for supporting shaft of continuously variable transmission in e.g. lorry, has damping coating arranged radially on surface at outer side of bearing outer ring

摘要

The unit (1) has a bearing inner ring (2), and a bearing outer ring (3) arranged radially at an outer side of the inner ring. Rolling bodies (4) are positioned between the inner and outer rings. A decoupling element (8) is designed as a vibration absorber and arranged radially at an outer side of the outer ring. The decoupling element lies partially on a section of a casing surface of the outer ring, and a damping coating e.g. anti-corrosion coating or elastomer coating, is arranged radially on a surface at the outer side of the outer ring, where the surface extends in an axial direction.
