Point of Selection Selection flow based on function conditions

The following fl owchart should be used as a guide for selecting a Guide Ball Bushing.

1. 1

   Setting Conditions

   • Stroke length: L_S
   • 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 Guide Ball Bushings and temporarily decide a rough size.

3. 3

   Examining Strength of the Shaft (Examining the LG 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. Selection According to the Operating Environment."
   FAIL: Return to "1. Setting Conditions."

6. 5

   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 guide ball bushing options page.
