This spherical roller bearing accommodates radial loads together with axial loads acting in both directions and compensates for shaft misalignment thanks to its two rows of rollers running on a common spherical outer ring raceway. Main dimensions follow DIN 635-2, with a bore diameter of 120.0 mm, outside diameter of 180.0 mm and width of 46.0 mm; net mass is 4.04 kg. The limiting speed is 3950 1/min and the reference speed is 2800 1/min. The design designation is E1A, with cylindrical bore type Z. The bearing is supplied with normal radial internal clearance (CN, Group N) and a machined cage designated M, giving stable roller guidance at the stated speed range. Its self-aligning design makes it suitable for applications where shaft deflection or housing misalignment must be tolerated without affecting load distribution across the rollers. Standard relubrication provision allows grease to be replenished during service without dismounting the bearing.
