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 race. Main dimensions follow DIN 635-2: bore diameter 85.0 mm, outside diameter 180.0 mm, width 60.0 mm, mass 7.115 kg. The bore is tapered at a ratio of 1:12 (bore type K), allowing mounting on a straight or tapered shaft seat with an adapter or withdrawal sleeve and control of the fit through axial drive-up. Limiting speed is 4100 1/min, reference speed 3200 1/min, and the cage is a polyamide type (JPA). Radial internal clearance corresponds to CN (Group N), suiting standard shaft and housing fits without added preload. The E1 design provides an optimized internal geometry for roller-raceway contact. Relubrication is standard, so the bearing can be regreased through the housing during service. The tapered bore simplifies mounting and dismounting where a shaft may deflect under load, since the self-aligning outer raceway compensates for such misalignment without generating additional internal stress.
