This spherical roller bearing accommodates radial loads combined with angular misalignment between shaft and housing, transmitting load through two rows of rollers guided on a common sphered outer raceway. It has a tapered bore (K, taper 1:12) for mounting on an adapter or directly on a tapered shaft seat, bore diameter 100.0 mm, outside diameter 165.0 mm, width 52.0 mm, net mass 4.262 kg. Limiting speed is 4000 1/min, reference speed 2750 1/min. The design is E1A, with a machined M cage. Radial internal clearance is CN (Group N), the standard clearance group, suitable for normal operating conditions without additional preload requirements. The tapered bore allows compensation for shaft tolerances and simplifies mounting and dismounting compared with a cylindrical bore, while the sphered raceway design permits the bearing to tolerate shaft deflection and housing misalignment during operation. Relubrication is standard, meaning the bearing is designed for periodic grease or oil replenishment through the housing.
