Basic Dynamic Load Rating

The basic load rating is defined as the constant load applied to bearings with stationary outer rings that the inner rings can endure for a rating life of one million revolutions (10 6 rev). The basic load rating of radial bearings is defined as a central radial load of constant direction and magnitude, while the basic load rating of thrust bearings is defined as an axial load of constant magnitude in the same direction as the central axis. The load ratings are listed under Cr for radial bearings and Ca for thrust bearings in the dimension tables
