This spherical roller bearing accommodates radial loads together with shaft misalignment through its symmetric roller and raceway geometry, featuring two outer ribs with a rib washer. Bore diameter is 300.0 mm, outside diameter 500.0 mm, width 160.0 mm, and net mass reaches 121.095 kg. The tapered bore (K) allows mounting on an adapter or withdrawal sleeve, while the machined brass cage (MB1) guides the rollers under load. Limiting speed is rated at 1300.0 1/min, with a reference speed of 720.0 1/min. Radial internal clearance falls within group CN (Group N), suitable for standard fit conditions without additional preload requirements. The tapered bore design (K) permits controlled adjustment of clearance during mounting on a shaft, compensating for shaft deflection and misalignment typical of heavy radial loading. Relubrication follows the standard feature, meaning grease replenishment is carried out through the standard arrangement without a dedicated relubrication device. The symmetric outer ring design with ribs and rib washer supports axial guidance of the rollers, contributing to stable running under combined radial and moderate axial loading.
