This spherical roller bearing accommodates angular misalignment and combined radial and axial loads through its two rows of rollers guided by a common sphered raceway in the outer ring. Main dimensions follow DIN 635-2, with a bore diameter of 180.0 mm, an outside diameter of 250.0 mm, and a width of 52.0 mm. Net mass is 7.535 kg. The tapered bore, taper 1:12 (bore type K), allows mounting on a tapered seat or with a sleeve, giving controlled adjustment of internal clearance during fitting. Limiting speed is 3200.0 1/min, with a reference speed of 1850.0 1/min. The bearing has a machined brass cage (MB), suited to higher speeds and providing stable roller guidance. Radial internal clearance corresponds to CN (Group N), the normal clearance range. The relubrication feature (S) allows grease replenishment during operation without dismounting the bearing. The tapered bore and self-aligning design suit applications where shaft deflection or housing misalignment must be compensated without loss of load-carrying capacity.
