This spherical roller bearing accommodates radial loads together with axial loads in both directions, using a two-row roller arrangement with a symmetric design featuring two outer ribs and a rib washer (design BEA). Bore diameter is 320.0 mm, outside diameter 480.0 mm, width 121.0 mm, and net mass 75.58 kg. The bearing runs in a machined brass cage (MB1) with C4 radial internal clearance, giving increased internal clearance compared to standard to compensate for thermal expansion and interference fit mounting. Limiting speed is 1480 1/min, reference speed 920 1/min. The spherical outer raceway allows self-alignment, so the bearing tolerates shaft deflection and housing misalignment without added edge stress on the rollers. The C4 clearance class suits applications with tight fits on the shaft or housing, or with elevated operating temperatures, where a standard clearance would run too tight. Relubrication is standard, meaning the bearing is designed for periodic grease replenishment rather than sealed-for-life operation.
