This spherical roller bearing accommodates angular misalignment and radial loads through its two rows of rollers guided on a common sphered outer ring raceway. The tapered bore, taper 1:12, allows mounting directly on a tapered shaft seat or with an adapter sleeve, giving a defined interference fit across the 140.0 mm bore. Outside diameter is 250.0 mm, width 68.0 mm, and net mass 13.688 kg. Limiting speed is rated at 3150.0 1/min, with a reference speed of 2250.0 1/min. The E1 design provides an optimized internal geometry for load distribution across the roller sets, and the K bore code confirms the tapered bore execution. The bearing is fitted with a JPA cage and runs with CN (Group N) radial internal clearance, suitable for standard fit and temperature conditions without added preload from mounting. Standard relubrication feature allows in-service greasing to maintain lubricant film under continuous operation. The self-aligning capability of the double row roller arrangement compensates for shaft deflection and housing misalignment, making this execution suitable where a tapered bore mounting is required together with a defined internal clearance class.
