Point of Selection Selection flow based on function conditions

The following flowchart should be used as a guide for selecting a Linear Bushing.

  1. 1

    Setting Conditions

    • Stroke length: LS
    • Velocity: V
    • Magnitude of the applied load: W
    • Mounting space
    • Operating frequency (duty cycle)
    • Required service life
    • Dimensions (No. of nuts, shafts, span)
    • Installation direction
    • Environment
    • Accuracy
  2. 2

    Selecting a Type

    Select a type that meets the service conditions from the classification table for Linear Bushings and temporarily decide a rough size.

  3. 3

    Examining Strength of the Shaft (Examining the LM Shaft Strength)

    • Estimating the shaft diameter
    • Estimating the shaft length
    • Method for fixing the shaft
    • Permissible load of the shaft
    • Displacement(deflection) of the shaft
  4. 4

    Predicting the Service Life

    Calculate the applied load and obtain the nominal life from the life calculation formula.

  5. Comparison with the
    required service life

    PASS: Proceed to "5. Determining the Accuracy."
    FAIL: Return to "1. Setting Conditions."

  6. 5

    Determining the Accuracy

    Select an accuracy grade

  7. 6

    Selection According to the Environment

    • Determining a lubricant
    • Determining a lubrication method
    • Determining a surface treatment
    • Designing contamination protection

    * Please refer to the lubrication, surface treatment, and contamination protection sections on the linear bushing options page.
