This spherical roller bearing accommodates shaft misalignment through its two rows of barrel-shaped rollers running on a common spherical raceway in the outer ring. Bore diameter is 80.0 mm, outside diameter 170.0 mm, width 39.0 mm, and net mass 4.419 kg. The limiting speed is rated at 5700 1/min, with a reference speed of 4050 1/min. The bearing features a cylindrical bore (bore type Z), a JPA cage, and design E1 with optimized internal geometry for reduced friction and heat generation. Radial internal clearance corresponds to C3 (Group 3), providing greater clearance than standard to compensate for thermal expansion and interference fits during operation. This clearance class makes the bearing suitable for applications where shaft deflection or housing misalignment must be tolerated without loss of running accuracy. Relubrication follows the standard feature, allowing periodic grease replenishment through conventional means during service intervals.
