This spherical roller bearing accommodates radial loads along with axial loads in both directions, using two rows of rollers set on a spherical outer ring raceway. Bore diameter is 180.0 mm, outside diameter 280.0 mm, width 74.0 mm, and net mass 16.473 kg. Limiting speed is rated at 2600.0 1/min, with a reference speed of 1760.0 1/min. The design is E1A, with a solid brass cage designated M and radial internal clearance in Group N (CN). The spherical outer ring raceway allows the bearing to compensate for shaft misalignment and deflection, making it suitable where precise shaft-housing alignment cannot be guaranteed. The CN clearance corresponds to standard operating conditions, and the cylindrical bore (type Z) permits straightforward mounting without the need for tapered sleeves. Standard relubrication features allow grease replenishment during service to maintain lubrication over the operating life of the bearing.
