2TS-DM assemblies are comprised of two single-row bearings with abutting back facing inner rings and an outer ring spacer with lubricating holes is typical. These are generally used at fixed positions on rotating shaft applications.

Design Attributes:
  • Two single row bearings, with or without a spacer
  • When spacers are used, bearing is furnished as a preset, matched assembly
  • Spacers available with or without lubricant grooves and holes
    • Unit of Measure

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