  • 1 Based on 90 x 106 revolutions L10 life, for The Timken Company life calculation method. C90 and Ca90 are radial and thrust values.
  • 2 Based on 1 x 106 revolutions L10 life, for the ISO life calculation method.
  • 3 Based on 1 x 106 revolutions L10 life, for the ISO life calculation method.
  • 4 Based on 90 x 106 revolutions L10 life, for The Timken Company life calculation method. C90 and Ca90 are radial and thrust values for a single-row, C90(2) is the two-row radial value.
  • 5 These factors apply for both inch and metric calculations. Consult your Timken representative for instruction on use.
  • 6 These maximum fillet radii will be cleared by the bearing corners.
  • 7 Negative value indicates effective center inside cone backface.
  • 8 Based on 90 x 106 revolutions L10 life, for The Timken Company life calculation method. C90 and Ca90 are radial and thrust values for a single-row, C90(2) is the two-row radial value.
