Application Summary AI generated
This standard specifies the boundary dimensions (bore diameter, outside diameter, width, and chamfer dimensions) for four-row tapered roller bearings. It is applied in the design, manufacturing, and procurement of these bearings, which are primarily used in heavy-duty rolling mill applications, such as backup rolls and work rolls in steel production. The standard ensures interchangeability and compatibility between bearing components and associated shaft and housing designs in industrial machinery.
