This spherical roller bearing accommodates angular misalignment between shaft and housing while carrying combined radial and axial loads. It features a tapered bore (taper 1:12), design K, allowing mounting on tapered shaft seats or with sleeves for a controlled interference fit. Main dimensions follow DIN 635-2: bore diameter 65.0 mm, outside diameter 140.0 mm, width 48.0 mm, net mass 3.493 kg. The cage is JPA, design E1, giving an optimized roller set and raceway geometry for load distribution. Limiting speed is 5000 1/min, reference speed 3800 1/min. Radial internal clearance C3 compensates for interference fit and temperature-driven expansion during operation, keeping the bearing properly preloaded once mounted on the tapered seat. The tapered bore simplifies mounting and dismounting compared to a cylindrical bore, and allows fine adjustment of internal clearance during fitting. Relubrication is standard, so the bearing can be regreased through the housing during service without disassembly.
