 NKE
offers its SQ77 electrically insulated rolling bearings, which feature
a built-in electrical insulation, which provides reliable protection
against current discharge and the resulting electrical corrosion.
Typical applications include electric motors, generators and other
electrical machines. They are available in three versions: the SQ77
series, with an oxide ceramic insulation layer on the outer ring; the
SQ77E series with an insulation layer on the inner ring and the hybrid
bearings of the SQ77B series which feature ceramic rolling elements
with theoretically infinite insulation resistance.
