This spherical roller bearing accommodates two rows of rollers guided on a common sphered outer ring raceway, allowing angular misalignment between shaft and housing. Main dimensions follow DIN 635-2: bore 120.0 mm, outside diameter 180.0 mm, width 46.0 mm, net mass 3.827 kg. The E1 design provides an optimized internal geometry for load distribution, the cage is a glass-fiber reinforced polyamide cage (TVPB), and radial internal clearance corresponds to CN (Group N). Limiting speed reaches 3950 1/min, with a reference speed of 2800 1/min under standard lubrication conditions. The CN clearance combined with the E1 internal design suits applications where shaft deflection or housing misalignment must be tolerated without loss of load capacity. The TVPB cage design supports smooth roller guidance and grease retention under standard relubrication practice, while the Z bore type indicates a cylindrical bore for direct mounting.
