Compensates for shaft misalignment and housing deflection through its two rows of balls running in a spherical outer ring raceway. This self-aligning ball bearing has a bore diameter of 40.0 mm, outside diameter of 90.0 mm, and width of 33.0 mm, with a net mass of 0.913 kg. It carries a glass-fibre reinforced plastic cage (TVH) and a cylindrical bore (Z). Limiting speed is rated at 7900 1/min, with a reference speed of 8700 1/min. Radial internal clearance corresponds to CN (Group N), the standard clearance group, suitable for general mounting conditions without additional preload requirements. The spherical outer ring design allows the bearing to accommodate angular misalignment between shaft and housing, making it suitable for applications where shaft deflection under load is expected. As an open bearing without integrated sealing, lubrication and protection against contamination must be provided externally, and relubrication intervals should be set according to operating speed and environment.
