Carries combined radial and axial loads in both directions from a single row of balls in angular contact with the raceways, allowing the ring cross-section to be split for assembly. The QJ209-XL-MPA has a bore diameter of 45.0 mm, outside diameter of 85.0 mm, and width of 19.0 mm, with a net mass of 0.5 kg. It uses a solid brass cage (MPA) and belongs to the X-life design line. Limiting speed is 16200.0 1/min, reference speed 7000.0 1/min. The four-point contact geometry lets this bearing take up axial forces from either direction with a single row, so it can replace two separate angular contact bearings mounted back to back where axial space is limited. The solid brass cage gives stable ball guidance at the stated speed ratings and supports operation under the combined radial-axial loading the design is intended for.
