This double row angular contact ball bearing carries the internal bore of 45.0 mm, outside diameter of 85.0 mm, and width of 30.2 mm, with a net mass of 0.611 kg. It belongs to the X-life design line, offering increased load carrying capacity within the standard envelope dimensions. The cage is a solid plastic TVH type, and the C2 designation indicates a radial internal clearance below normal, tightening axial and radial play in the arrangement. The double row angular contact design takes up axial loads from both directions within a single bearing, together with radial loads, and locates a shaft with defined axial position. The reduced internal clearance of C2 suits applications where minimal axial play is required, while the plastic TVH cage supports smooth ball guidance at speed. Limiting speed is rated at 8300 1/min, with a reference speed of 8400 1/min, giving the operating thresholds for the given bore and clearance class.
