This spherical roller bearing has a symmetric roller design with a rib washer construction, bore diameter 150.0 mm, outside diameter 250.0 mm, and width 100.0 mm, giving a net mass of 19.6 kg. The limiting speed is rated at 2370.0 1/min, with a reference speed of 1270.0 1/min. Radial internal clearance corresponds to CN (Group N), the cage is made of JPB material, and the design follows the BE type with a Z-type bore. The symmetric roller profile allows the bearing to accommodate shaft misalignment while maintaining even load distribution across the rolling elements. Standard CN clearance suits general-purpose radial and axial loading in both directions. The JPB cage provides stable roller guidance under continuous operation, while the standard relubrication feature allows grease replenishment during service without disassembly. The cylindrical bore type Z permits direct mounting on a straight shaft.
