This spherical roller bearing accommodates two rows of rollers guided on a common sphered raceway in the outer ring, allowing angular misalignment between shaft and housing. Main dimensions follow DIN 635-2: bore 45.0 mm, outside diameter 85.0 mm, width 23.0 mm, mass 0.562 kg. Limiting speed is 10100 1/min, reference speed 5600 1/min. The E1 design uses an optimized internal geometry for increased load rating, the cage is a polyamide type (JPA), and the bore is cylindrical (Z). Radial internal clearance corresponds to CN (Group N), suitable for standard fit conditions without preload. The design tolerates shaft deflection and misalignment resulting from the self-aligning raceway geometry. No integrated seals are fitted, so relubrication follows the standard feature via grease or oil through the housing arrangement, and mounting requires external sealing if contamination protection is needed.
