This spherical roller bearing carries radial loads and accommodates shaft misalignment through its two rows of barrel-shaped rollers running on a spherical outer raceway with symmetric outer ribs. Bore diameter is 70.0 mm, outside diameter 150.0 mm, width 51.0 mm, and net mass 4.266 kg. The design is E1A with a machined M cage, cylindrical bore (Z), and CN radial internal clearance. Limiting speed is rated at 4800 1/min, with a reference speed of 3700 1/min. The CN clearance combined with the machined cage suits applications where shaft deflection or housing misalignment must be tolerated without loss of running accuracy. Standard relubrication feature allows grease replenishment through the bearing during service, supporting continuous operation at the stated speed ratings. The symmetric outer rib design aids roller guidance and load distribution across both rows under radial loading conditions.
