This single row angular contact ball bearing carries a 40° contact angle design with a solid brass cage (MP), bore diameter 120.0 mm, outside diameter 215.0 mm and width 40.0 mm. Net mass is 6.071 kg. The X-life design provides increased load rating within standard boundary dimensions. Limiting speed is 5200 1/min, reference speed 3700 1/min. The single row arrangement takes combined radial and axial load in one direction, so a mating bearing is required for the opposite axial direction. The solid brass cage gives stable ball guidance and reliable performance at higher speeds, which supports operation close to the stated limiting speed. The bearing is supplied open, without integrated sealing, so lubrication and contamination protection must be provided by the housing design.
