This spherical roller bearing accommodates angular misalignment between shaft and housing through its two rows of barrel-shaped rollers running on a common spherical outer raceway. Main dimensions follow DIN 635-2: bore 55.0 mm, outside diameter 100.0 mm, width 25.0 mm, net mass 0.805 kg. The bore is tapered at 1:12 (bore type K), allowing mounting on a tapered seat or with a sleeve. Limiting speed is 9000 1/min, reference speed 4650 1/min. Design E1 features an optimized internal geometry for higher load rating, and the cage is a pressed steel type designated JPA. Radial internal clearance is CN (Group N), suitable where standard operating clearance is required. The tapered bore simplifies mounting and allows clearance adjustment during fitting, making the bearing tolerant of shaft deflection and slight misalignment. No integrated seals are provided, so relubrication follows a standard grease or oil regime depending on operating conditions and housing design.
