This spherical roller bearing accommodates radial loads while compensating for shaft misalignment, with a spherical raceway on the outer ring allowing two rows of rollers to self-align relative to the housing. The 23088-BEA-XL-MB1-R50-130 has a bore diameter of 440.0 mm, an outside diameter of 650.0 mm, and a width of 157.0 mm, with a net mass of 176.5 kg. The symmetric design features two outer ribs with a rib washer, machined bronze cage MB1, and a Z-type bore. Limiting speed is rated at 1030.0 1/min, with a reference speed of 610.0 1/min. The MB1 cage design supports stable roller guidance at the stated speed range, and the symmetric roller profile distributes load evenly across both rows under misalignment conditions. Standard relubrication feature allows grease replenishment through the bearing during service without disassembly. The Z-type bore suits mounting directly on a cylindrical shaft, and the construction is suited to applications requiring radial load capacity combined with tolerance for shaft deflection or housing misalignment.
