Inch Taper Roller Bearing Description
Tapered roller bearings consist of four interdependent components: the cone (inner ring), the cup (outer ring), the tapered rollers (rolling elements) and the cage (roller retainer). Tapered roller bearings are uniquely designed to manage both thrust and radial loads between a rotating and non-rotating member. The steeper the cup angle, the greater the ability of the bearing to handle thrust loads.

Taper Roller Bearings Applications
- 1 These maximum fillet radii will be cleared by the bearing corners.
- 2 These maximum fillet radii will be cleared by the bearing corners.
- 3 Negative value indicates effective center inside cone backface.
- 4 Based on 90 x 106 revolutions L10 life, for The Timken Company life calculation method. C90 and Ca90 are radial and thrust values.
- 5 Based on 1 x 106 revolutions L10 life, for the ISO life calculation method.
- 6 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.
- 7 These factors apply for both inch and metric calculations. Consult your Timken representative for instruction on use.
- 8 These factors apply for both inch and metric calculations. Consult your Timken representative for instruction on use.
- 9 These factors apply for both inch and metric calculations. Consult your Timken representative for instruction on use.
- 10 Geometry constant for Lubrication Life Adjustment Factor a3l.
