This double row angular contact ball bearing has a bore diameter of 45.0 mm, an outside diameter of 100.0 mm, and a width of 39.7 mm, with a net mass of 1.36 kg. It is built to the X-life standard with a steel sheet metal cage (JH) and shields (2Z) on both sides. The limiting speed is 5500 1/min, with a reference speed of 6700 1/min. The double row angular contact design allows it to carry combined radial and axial loads in both directions, with a fixed relative position of the two rows contributing to defined internal geometry and stiffness under load. The steel sheet metal cage supports smooth ball guidance at the rated speeds, while the shields on both sides protect the bearing interior from external contamination, making regreasing intervals less critical during operation. The C3 internal clearance accommodates thermal expansion during operation, which should be considered when selecting the fit on the shaft and housing.
