This spherical roller bearing carries radial loads together with axial loads in both directions and accommodates shaft misalignment thanks to its two-row symmetric roller design with a rib washer arrangement (BEA). Bore diameter is 280.0 mm, outside diameter 500.0 mm, width 176.0 mm, and net mass is 142.855 kg. The limiting speed reaches 1280.0 1/min, with a reference speed of 630.0 1/min. The tapered bore (K) allows mounting with an adapter or withdrawal sleeve, giving precise control over the internal clearance during fitting. The C3 radial internal clearance compensates for temperature-related expansion and interference fit effects during operation, making the bearing suitable for applications where shaft deflection or alignment error must be tolerated. The MB1 machined brass cage provides stability at the stated speed range and supports reliable roller guidance under load. Standard relubrication feature allows in-service lubrication without disassembly, maintaining consistent grease distribution across the raceways throughout the operating life of the bearing.
