Load carrying quick reference table

The table shown is a rapid means of selection for radial (P) and axial (P_a) loads, based on statistical fatigue (L₁₀) life of 30,000 hours and a safety factor of 1.2 for steady loads. For other conditions and appropriate safety factors, see the engineering section in this catalog.

If the axial or radial loads exceeds the values shown on this page, please contact our technical department
