¹ Based on 1 x 10⁶ revolutions L₁₀ life, for the ISO life calculation method.
² Based on 90 x 10⁶ revolutions L₁₀ life, for The Timken Company life calculation method. C₉₀ and C_a90 are radial and thrust values for a single-row, C₉₀₍₂₎ is the two-row radial value.
³ These maximum fillet radii will be cleared by the bearing corners.
⁴ Negative value indicates effective center inside cone backface.
⁵ Based on 90 x 10⁶ revolutions L₁₀ life, for The Timken Company life calculation method. C₉₀ and C_a90 are radial and thrust values.
⁶ Based on 1 x 10⁶ revolutions L₁₀ life, for the ISO life calculation method.
⁷ Based on 90 x 10⁶ revolutions L₁₀ life, for The Timken Company life calculation method. C₉₀ and C_a90 are radial and thrust values for a single-row, C₉₀₍₂₎ is the two-row radial value.
⁸ These factors apply for both inch and metric calculations. Consult your Timken representative for instruction on use.
⁹ Geometry constant for Lubrication Life Adjustment Factor a3l.
