This spherical roller bearing accommodates radial loads with angular misalignment between shaft and housing, made possible by its two rows of rollers running on a common sphered outer raceway. Main dimensions follow DIN 635-2: bore 55.0 mm, outside diameter 120.0 mm, width 43.0 mm, net mass 2.301 kg. The tapered bore (K, taper 1:12) allows mounting on a tapered shaft seat or with an adapter/withdrawal sleeve, giving a defined interference fit without the need for a stepped shaft. Limiting speed is 5800 1/min, reference speed 4500 1/min. The C3 radial internal clearance (Group 3) compensates for the interference generated during mounting on the tapered seat and for temperature-related expansion during operation, keeping the bearing from running with excessive preload. The E1 design and JPA cage (polyamide, roller-guided) contribute to load distribution across the rollers and support the reference speed rating. Standard relubrication feature allows grease replenishment during service. The tapered bore combined with the self-aligning two-row roller design suits applications where shaft deflection or housing misalignment must be tolerated without loading the bearing edges.
