This spherical roller bearing accommodates angular misalignment and radial loads through its two rows of rollers running on a common sphered outer raceway. It features a tapered bore (taper 1:12), bore diameter 110.0 mm, outside diameter 180.0 mm, and width 56.0 mm, with a net mass of 5.357 kg. Design E1A defines the internal geometry, and the cage is executed in version M. Limiting speed is rated at 3700 1/min, with a reference speed of 2550 1/min. Internal clearance is set to C3 (Group 3), providing additional radial play to compensate for interference fit on the tapered bore and for thermal expansion during operation. Bore type K allows mounting on a tapered seat, either directly or with an adapter or withdrawal sleeve, simplifying installation and dismounting. Relubrication is standard, so the bearing can be replenished with grease through its housing arrangement during service without disassembly.
