Compensates for shaft misalignment thanks to a spherical outer ring seated in a matching housing, while the inner ring is machined for a standard fit on the shaft. Bore diameter is 45.0 mm, outside diameter 85.0 mm, width 19.0 mm, and net mass 0.37 kg. Sealing on both sides is of the NPP type, integrated into the outer ring. This deep groove ball bearing suits mounting locations where shaft deflection or housing bore misalignment cannot be fully avoided, since the spherical outer ring surface allows the bearing to self-align without inducing additional internal stress. The NPP seals on both sides restrict lubricant loss and limit ingress of dust and moisture, so the bearing can operate with reduced maintenance attention once the initial grease fill is in place.
