This spherical roller bearing accommodates radial loads together with angular misalignment between shaft and housing, using two rows of rollers guided on a common sphered raceway in the outer ring. The bore is tapered at 1:12 (design K), allowing mounting on a tapered shaft seat or with a sleeve, main dimensions follow DIN 635-2. Bore diameter is 110.0 mm, outside diameter 180.0 mm, width 56.0 mm, mass 5.36 kg. Limiting speed is 3700 1/min, reference speed 2550 1/min. Design E1A, cage M (machined brass cage). Radial internal clearance is CN (Group N), suitable where shaft deflection or alignment error must be compensated without inducing excessive internal stress on the rollers. The tapered bore permits controlled clearance reduction during mounting, and standard relubrication feature supports periodic grease replenishment without dismounting the bearing from its housing.
