This spherical roller bearing accommodates shaft misalignment through its two rows of rollers running on a common sphered outer raceway, allowing angular deflection while carrying combined radial and axial loads. Main dimensions follow DIN 635-2, with a bore of 40.0 mm, outside diameter of 90.0 mm, and width of 33.0 mm; net mass is 0.997 kg. The tapered bore, taper 1:12 (K), enables mounting on tapered seats or with sleeves, giving controlled interference fit and adjustable internal clearance during installation. Limiting speed is 7600 1/min, reference speed 5500 1/min. Radial internal clearance corresponds to C3 (Group 3), suited for applications where thermal expansion or interference fit reduces the initial clearance, keeping operating clearance within the normal range. The E1 design and JPA cage reduce internal friction and support stable roller guidance at the stated speeds, while the standard relubrication feature allows grease replenishment during service without dismounting the bearing.
