This spherical roller bearing accommodates angular misalignment and radial loads through its two rows of rollers guided on a common sphered outer raceway. Main dimensions follow DIN 635-2: bore diameter 65.0 mm, outside diameter 140.0 mm, width 48.0 mm, net mass 3.495 kg. The bore is tapered (K, taper 1:12), allowing mounting on a tapered seat or adapter sleeve with a controlled interference fit. Limiting speed is 5000 1/min, reference speed 3800 1/min. The cage is a machined polyamide type (JPA), and radial internal clearance corresponds to the CN (Group N) range, suitable for standard fit conditions. The E1 design provides an optimized internal geometry for load distribution across the rollers. As the bearing is open (unsealed), relubrication follows the standard scheme, requiring external sealing and periodic grease or oil replenishment depending on the application's operating conditions.
