This spherical roller bearing carries radial loads together with axial loads in both directions, allowing the two rows of rollers to compensate for shaft misalignment. It has a bore diameter of 150.0 mm, outside diameter of 320.0 mm, and width of 108.0 mm, with a net mass of 40.448 kg. The tapered bore, taper 1:12, bore type K, permits mounting on a tapered shaft seat or with a sleeve, giving controlled interference fit during installation. Main dimensions follow DIN 635-2. Limiting speed is 2290.0 1/min, reference speed 1520.0 1/min. The design E1 profile increases load carrying capacity within the same envelope dimensions, and the JPA cage guides the rollers under the increased radial internal clearance of group C3, which compensates for the tighter fit resulting from mounting on the tapered bore. This clearance class suits applications where operating temperature and interference fit reduce the initial internal clearance, keeping the bearing free of excessive preload once mounted. Relubrication is standard, so the bearing accepts periodic replenishment of grease through its relubrication feature during service.
