This spherical roller bearing accommodates shaft misalignment through its two rows of rollers running on a common sphered outer raceway. It features a tapered bore with a taper of 1:12, coded K, allowing mounting on a tapered shaft seat or with an adapter sleeve. Main dimensions follow DIN 635-2: bore diameter 45.0 mm, outside diameter 85.0 mm, width 23.0 mm, net mass 0.56 kg. The E1 design provides an optimized internal geometry and roller guidance, and the JPA cage guides the rollers within the bearing. With radial internal clearance in class CN (Group N), the bearing runs with standard clearance suited to normal fits and operating temperatures. Limiting speed is 10100 1/min and reference speed 5600 1/min, giving the thermally and mechanically permissible speed limits for this size. The tapered bore permits adjustment of the fit and clearance during mounting, compensating for shaft deflection and misalignment. Relubrication follows the standard feature, meaning no special lubrication grooves or holes are provided beyond the standard configuration.
