This spherical roller bearing accommodates radial loads together with angular misalignment between shaft and housing, transmitting them across two rows of rollers guided on a common sphered raceway in the outer ring. Bore diameter is 150.0 mm, outside diameter 270.0 mm, width 73.0 mm, and net mass 17.37 kg. The bearing has a tapered bore, taper 1:12 (K), design E1, with a JPA cage. Limiting speed is rated at 2900.0 1/min, reference speed at 2050.0 1/min. The tapered bore allows mounting directly on a tapered shaft seat or with the use of a sleeve, giving controlled adjustment of internal clearance during fitting. Radial internal clearance is C3, larger than normal, which compensates for interference fit and thermal expansion during operation. The design permits shaft deflection and misalignment without inducing additional internal stress, and the standard relubrication feature allows grease replenishment without dismounting the bearing.
