This spherical roller bearing accommodates angular misalignment between shaft and housing while carrying radial loads along with axial loads in both directions. The bore is tapered at a ratio of 1:12, allowing mounting on a tapered shaft seat or with a sleeve, with a bore diameter of 55.0 mm, outside diameter of 120.0 mm, and width of 43.0 mm. Main dimensions follow DIN 635-2. Net mass is 2.301 kg. The limiting speed is 5800 1/min, with a reference speed of 4500 1/min. The bearing has radial internal clearance in group CN and is fitted with a JPA cage. Design E1 provides an optimized internal geometry for load distribution across the rollers. The tapered bore (bore type K) allows adjustment of internal clearance during mounting by controlling the drive-up onto the shaft or sleeve, which is useful where precise clearance setting is required after installation. Relubrication follows the standard configuration, with grease as the lubricant.
