This angular contact ball bearing transfers combined radial and axial loads through a double row of balls arranged with a defined contact angle, allowing load transmission in both axial directions. The design includes a filling slot for ball insertion, which permits a higher ball count per row. Bore diameter is 70.0 mm, outside diameter 150.0 mm, width 63.5 mm, and net mass is 4.646 kg. The bearing is fitted with a steel sheet metal cage (J). Limiting speed is rated at 4750 1/min, with a reference speed of 4500 1/min. The double-row arrangement provides rigid axial guidance in both directions from a single bearing, reducing the need for a paired setup. The filling-slot design increases the number of rolling elements, raising radial load capacity within the given envelope size. The steel sheet metal cage keeps the assembly light while maintaining ball spacing at the stated speed ratings. Its bore and outside diameter make it a direct fit for shaft and housing dimensions matching 70.0 mm and 150.0 mm respectively, at the given width of 63.5 mm.
