This spherical roller bearing accommodates radial loads together with angular misalignment between shaft and housing, made possible by its two rows of rollers running on a common sphered outer ring raceway. The 22315-E1-XL-K has a tapered bore (taper 1:12), with bore diameter 75.0 mm, outside diameter 160.0 mm and width 55.0 mm, weighing 5.174 kg. Main dimensions follow DIN 635-2. The limiting speed is 4500 1/min, with a reference speed of 3550 1/min. The tapered bore allows mounting on a straight or tapered seat with an adapter or withdrawal sleeve, simplifying fitting and enabling control of the operating clearance during installation. Radial internal clearance is CN (Group N), and the polyamide cage (JPA) reduces mass and friction at the rolling contact. The E1 design provides increased load carrying capacity compared with earlier generations of the same envelope dimensions. Relubrication follows the standard feature, and the misalignment capability inherent to the spherical design permits operation under shaft deflection or housing misalignment.
