This angular contact ball bearing carries axial loads acting in two directions through a paired arrangement of contact angle raceways, giving the assembly high axial rigidity at a defined position on the shaft. Bore diameter is 30.0 mm, outside diameter 80.0 mm, width 56.0 mm, and net mass is 1.466 kg. The bearing is fitted with 2Z shielding on both sides, protecting the raceway and ball complement from external contamination. The double-row design and the 2Z shielding make this bearing suitable for applications requiring precise axial positioning combined with a closed bearing arrangement that reduces the need for external protective covers. Its geometry allows it to take up axial forces from both directions while maintaining defined running accuracy, and the integrated shields keep the internal grease fill in place, supporting maintenance-reduced operation once mounted.
