How to Read the Table
Example A: For a 1” standard duty ball bearing operating at 1000 RPM and desired 100,000 hours L10 life, 154 Lbs is the maximum allowable radial load.
Example B: If 230 lbs of radial load is applied to a 1” standard duty shaft operating at 1000 RPM, the resulting L10 life is 30,000 hours.
