- 1 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.
- 2 These factors apply for both inch and metric calculations. Consult your Timken representative for instruction on use.
- 3 These factors apply for both inch and metric calculations. Consult your Timken representative for instruction on use.
- 4 These maximum fillet radii will be cleared by the bearing corners.
- 5 These maximum fillet radii will be cleared by the bearing corners.
- 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 Ca90 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.
