This spherical roller bearing carries radial loads while tolerating angular misalignment between shaft and housing, using two rows of rollers running on a common spherical raceway in the outer ring. Bore diameter is 70 mm, outside diameter 125 mm, width 31 mm, net mass 1.6 kg. Limiting speed reaches 6700 1/min, reference speed 3950 1/min. The E1 design gives an optimized internal geometry for higher load carrying capacity, and the cage is a pressed steel JPA type. The bore is cylindrical (bore type Z), and C3 internal clearance compensates for thermal expansion during operation as well as shaft deflection under load, making the bearing tolerant of moderate misalignment. The standard relubrication feature permits re-greasing through the bearing during service, which supports longer intervals between maintenance.
