This four-point contact bearing carries radial and axial loads in both directions, making it suitable for single-row support of shafts where two-directional axial guidance is needed without a second bearing. The QJ208-XL-MPA has a bore diameter of 40.0 mm, outside diameter of 80.0 mm, and width of 18.0 mm, with a net mass of 440.0 g. It is fitted with a solid brass cage (MPA) and belongs to the X-life series, offering a limiting speed of 17500.0 1/min and a reference speed of 7500.0 1/min. The split inner ring design allows the bearing to accept combined loads while keeping a compact axial footprint compared to a two-bearing arrangement. The solid brass cage guides the balls securely at higher speeds and supports stable operation up to the stated limiting speed, while the reference speed value reflects typical thermal running conditions under standard lubrication.
