Selection Criteria Selection flow based on function conditions

The following flowchart can be used as reference for selecting an LM Guide.

1
Setting Conditions

Set conditions necessary for designing load on the LM Guide.
- Mounting orientation
- Symbol for number of axes
2

Selecting a Type

Select a type that meets the conditions and temporarily decide a rough size.
3
Applied Load

Calculate the applied load on the LM block.
- Calculating the applied load
- Load rating of the LM Guide in all directions
4

Equivalent Load

Convert the load applied on each LM block
in each direction into an equivalent load.
- Prediction the Rigidity
  
  Selecting a Radial Clearance (Preload)
  
  Service Life with a Preload Considered
  
  Rigidity
  
  Radial Clearance Standard for Each Model
  
  Designing the Guide System
  
  Based on the results of the investigation, proceed to "Comparison with the Required Service Life"
- Determining the Accuracy
  
  Accuracy Standards
  
  Guidelines for Accuracy Grades by Machine Type
  
  Accuracy Standard for Each Model
  
  Based on the results of the investigation, proceed to "Comparison with the Required Service Life"
5

Static Safety Factor

Obtain the value of static safety factor from the basic static load rating and the maximum applied load.
Judgment on the
static safety factor

PASS: Proceed to "6. Calculating the Average Load."
6

Average Load

Average the applied load, which fluctuates during operation, to convert the value to an average
7

Nominal Life

Calculate the the distance traveled based on the nominal life equation.
Comparison with the
required service life

PASS: Proceed to "8. Selection According to the Environment."
FAIL: Return to "1. Setting Conditions/2. Selecting a Type."
8
Selection According to the Environment
- Contamination Protection
- Lubrication Type of lubricant, lubrication method
- Corrosion Prevention Material, surface treatment
Selection Completed
