This spherical roller bearing accommodates radial loads together with angular misalignment between shaft and housing, made possible by its two rows of rollers running on a common sphered outer ring raceway. The tapered bore, taper 1:12 (bore type K), allows mounting directly on a tapered shaft seat or with an adapter/withdrawal sleeve, giving a controlled interference fit rather than a straight bore fit. Main dimensions follow DIN 635-2: bore diameter 80.0 mm, outside diameter 140.0 mm, width 33.0 mm, net mass 2.022 kg. The polyamide cage (JPA) combined with the E1 design supports operation at the limiting speed of 6200 1/min and reference speed of 3550 1/min. Radial internal clearance C4 (Group 4) is above normal, compensating for the interference generated by the tapered bore mounting and for thermal expansion during operation, keeping the bearing from running too tight once fitted and preloaded. Being an open bearing with standard relubrication feature, it requires external sealing and periodic grease replenishment through the housing, and is suited to applications where shaft deflection or alignment error must be tolerated without inducing edge loading on the rollers.
