This single row angular contact ball bearing carries balls positioned at a fixed contact angle within a solid brass cage (MP), guided by the X-life design for optimised internal geometry. Bore diameter is 100.0 mm, outside diameter 180.0 mm, width 34.0 mm, and net mass is 3.575 kg. Limiting speed reaches 6300 1/min, with a reference speed of 4250 1/min. The single-row angular contact design allows the bearing to take up axial loads in one direction combined with radial loads, and it is typically arranged in pairs or sets where two-directional axial loading is required. The solid brass cage provides stable ball guidance and strength at elevated speeds, supporting operation up to the stated limiting speed. As supplied without integrated sealing, lubrication must be provided externally and matched to the operating speed and load conditions.
