This spherical roller bearing accommodates angular misalignment and combined radial and axial loads through its two rows of barrel-shaped rollers on a common spherical raceway. The tapered bore, taper 1:12, allows mounting directly on a tapered shaft seat or with the use of an adapter or withdrawal sleeve, giving a defined, adjustable fit. Main dimensions follow DIN 635-2: 120.0 mm bore, 215.0 mm outside diameter, 76.0 mm width, net mass 10.913 kg. Limiting speed is 3000 1/min, reference speed 1910 1/min. The polymer cage (TVPB) guides the rollers with low friction and reduced weight, suiting operation under moderate to elevated speeds within the stated limits. Radial internal clearance is CN (normal, Group N), matching standard shaft and housing fits without additional clearance selection. The E1 design provides an optimized internal geometry for increased load carrying capacity, while the K bore type confirms the tapered bore execution. Relubrication follows the standard feature, suitable for periodic grease or oil replenishment during service.
