JHM522649 Timken Tapered Roller Bearing Single Cone Only Timken JHM 522649 USA
This is the most basic and most widely used type of tapered roller bearing. It consists of two main separable parts: the cone (inner ring) assembly and the cup (outer ring). It is typically mounted in opposing pairs on a shaft.

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 Ca90 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 Ca90 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 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.
