This self-aligning ball bearing carries two rows of balls running on a common spherical raceway in the outer ring, allowing the outer ring axis to swivel relative to the inner ring and compensate for shaft misalignment or housing bore deviation. Bore diameter is 80.0 mm, outside diameter 140.0 mm, width 33.0 mm, and the unit weighs 2.01 kg. Radial internal clearance is CN (Group N), the cage is a glass-fibre reinforced polyamide cage (TVH), and the bore type is cylindrical (Z). Limiting speed is 5300 1/min, with a reference speed of 5400 1/min. The spherical raceway design lets the bearing accommodate angular misalignment between shaft and housing without generating additional internal stress, making it suitable for applications where shaft deflection or mounting inaccuracy is expected. The TVH plastic cage offers low friction and smooth ball guidance at the given speed ratings, while the CN clearance provides standard internal play for typical operating conditions. As supplied, the bearing is open and requires lubrication and sealing arrangements to be provided in the housing.
