This spherical roller bearing carries radial loads and accommodates shaft misalignment through its two rows of barrel-shaped rollers running on a common spherical raceway in the outer ring, which features symmetric two-piece outer ribs (design E1A). Bore diameter is 100.0 mm, outside diameter 180.0 mm, width 46.0 mm, and net mass is 4.843 kg. The bearing has a tapered bore (K) for mounting on an adapter or withdrawal sleeve, a machined brass cage (M), and radial internal clearance C4 (Group 4). Limiting speed is 4550.0 1/min, reference speed 3150.0 1/min. The tapered bore with K designation allows mounting with an adapter sleeve, simplifying axial positioning and enabling adjustment of the fit on the shaft. The C4 clearance compensates for the tighter fit resulting from mounting on a tapered seat, maintaining proper operating clearance once installed. The machined brass cage (M) guides the rollers reliably at the given speed range, while the symmetric outer ring rib design supports even load distribution across both roller rows under misalignment. Relubrication follows the standard feature for this series.
