This spherical roller bearing accommodates angular misalignment and combined radial and axial loads thanks to its two rows of rollers running on a common spherical raceway in the outer ring. It features a tapered bore with 1:12 taper (bore type K), bore diameter 25.0 mm, outside diameter 52.0 mm, width 18.0 mm, and net mass 0.168 kg. The limiting speed is 14400 1/min, with a reference speed of 9200 1/min. Design E1 provides an optimized internal geometry and roller guidance for reduced friction and heat generation. The cage is of JPA type, machined and pin-type, guided on the rollers. The tapered bore allows mounting on an adapter sleeve or directly on a tapered shaft seat, simplifying fitting and enabling radial internal clearance adjustment during installation. Radial internal clearance corresponds to CN (Group N), suitable for standard fit and load conditions. Main dimensions comply with DIN 635-2, ensuring dimensional interchangeability with other bearings of the same series. Relubrication follows the standard feature, allowing grease replenishment through the bearing during service without disassembly.
