This spherical roller bearing carries radial and combined axial loads through two rows of symmetric rollers guided in a JPB cage, with a rib washer on the BE design outer ring and a Z type bore. Bore diameter is 160.0 mm, outside diameter 270.0 mm, width 109.0 mm, net mass 25.044 kg. Limiting speed is 2180.0 1/min, reference speed 1140.0 1/min, with standard relubrication feature. Radial internal clearance C2 (Group 2) is tighter than standard clearance, suiting mounting conditions where fits on the shaft and in the housing already reduce operating clearance. The symmetric roller profile and rib washer let the bearing accommodate shaft misalignment while carrying combined loads, and the JPB cage supports steady operation up to the stated reference and limiting speed values.
