This spherical roller bearing accommodates shaft misalignment through its two rows of barrel-shaped rollers guided on a common sphered raceway in the outer ring. Main dimensions follow DIN 635-2: bore diameter 70.0 mm, outside diameter 150.0 mm, width 51.0 mm, net mass 4.0 kg. The bore is tapered 1:12 (bore type K), allowing mounting on a tapered shaft seat or with a sleeve for controlled clearance reduction. Limiting speed is 4800 1/min, reference speed 3700 1/min. The cage is a pressed steel design (JPA), and the E1 design denotes an optimized internal geometry for increased load rating. Radial internal clearance C3 (Group 3) compensates for the interference fit resulting from the tapered bore mounting and for thermal expansion during operation, maintaining proper operating clearance once the bearing is fitted. The tapered bore simplifies mounting and dismounting compared with a cylindrical bore, and allows adjustment of the fit along the shaft. Relubrication follows the standard feature, meaning the bearing is designed for lubrication through conventional means rather than an integrated relubrication device. The self-aligning capability of the spherical roller design makes it suitable where shaft deflection or housing misalignment must be tolerated without inducing edge loading on the rollers.
