This spherical roller bearing carries a 120.0 mm bore, 180.0 mm outside diameter and 46.0 mm width, with a netto mass of 4.026 kg. The E1A design uses a solid brass cage (M) and cylindrical bore (Z), rated for a limiting speed of 3950.0 1/min and a reference speed of 2800.0 1/min. Radial internal clearance is set to C2 (Group 2), tighter than standard clearance. The spherical raceway geometry allows the bearing to accommodate shaft misalignment and deflection under radial load. Tighter C2 clearance suits applications where operating temperature and fit conditions would otherwise open up clearance beyond the intended range. Relubrication follows the standard feature, so grease replenishment through the housing is possible without dismantling the bearing.
