Technical calculations

■Operating Life Calculation for Linear Guides

●Operating Life
When the linear guide is loaded in linear reciprocating motion, scaly damages called flaking appear due to material fatigue as the stress works on the rolling elements (steel balls) and the rolling contact surfaces (rails) constantly. Total travel distance until the first flaking occurs is called the life of linear guides.
●Rated Life
Rated life is the total travel distance that 90% of linear guides of the same type can reach, under the same conditions, with no occurrence of flaking damage. Rated life can be calculated with the basic dynamic load rating and the actual load applied on the linear guides, as shown below.
Load must be calculated before actually using linear guides. To obtain loads during linear reciprocating motion, it is necessary to fully consider vibrations and impacts during motion as well as distribution condition of the load applied to linear guides. So, it is not easy to calculation the loads. Operating temperature also critically affects the life. Considering these conditions, the above-mentioned calculation formula will be as follows.
  • L: Rated Life (Km)
  • fH: Hardness Factor (See Fig.1)
  • fT: Temperature Factor (See Fig.2)
  • fC: Contact Factor (See Table-1)
  • fW: Load Factor (See Table-2)
  • C: Basic Dynamic Load Rating (N)
  • P: Applied Load (N)
●Hardness factor (fH)

For liner guide applications, sufficient hardness is required for ball contact shafts. Inappropriate hardness causes less allowable load, resulting in shorter life.
Please correct the rated life with the hardness factor.

●Temperature factor (fT)

When the temperature of linear guides exceeds 100°C, the hardness of guides and shafts will be reduced, and the allowable loads will also be reduced compared to being used at room temperature, causing a reduction of life. Please correct the rated life with the temperature factor.
* Please use Linear Guides at within the heat resistance temperature ranges shown on product pages.

●Contact factor (fC)

Table-1. Contact Factor

Number of blocks per rail Contact factor fC

1 1.00
2 0.81
3 0.72
4 0.66
5 0.61

For actual applications, more than two blocks are generally used per shaft. In this case, the load applied to each block varies depending on machining precision and is not uniformly distributed. As a result, per-block allowable load varies depending on the number of blocks per rail. Please compensate the rated life with contact factors on Table-1.

●Load Factor (fW)

Table-2. Load Factor

Condition of Use fw
No shocks / vibrations,
low speed: 15 m/min. or less
1.0-1.5
No significant shocks / vibrations,
medium speed: 60 m/min. or less
1.5-20
With shocks / vibrations,
high speed: 60 m/min. or more
2.0-3.5

To calculate load applied to the Linear Guides, in addition to object weight, it requires inertia force attributed to motion velocity or moment loads. However, it is difficult to calculation the load accurately due to potential vibrations and shocks caused by other element than repeated start-stop motions during reciprocating motion. Thus, Table-2 load factor helps simplify the life calculation.

●Applied Load P Calculation Method
When moment load is applied to each block, convert the moment load into applied load by the following formula.
  • P: Applied Load (N)
  • F: Downward load (N)
  • C0: Static load rating (N)
  • MA: Allowable Static Moment - Pitching Direction (N·m)
  • MC: Allowable Static Moment - Rolling Direction (N·m)
  • Lp: Load point distance (m) in pitching direction
  • Lr: Load point distance (m) in rolling direction

Application Overview

Purpose

  • Purpose: Table positioning
    Operation: Moves the table to the desired position by motor belt drive.
  • Transports elevator units installed on the table.
    Table weight: 1.5 kg
    Elevator unit weight: 3.5 kg

Design Specifications

Operating Conditions or Design Requirements

  • External dimensions: W 1710 x D 198 x H 237 mm
    Stroke: 1205 mm

Required Performance

  • Transportation load: 50 N
  • Stop accuracy ± 0.5 mm

Selection Criteria for Main Components

  • Select a motor to move load of 50 N.

Design Evaluation

Verification of main components

  • Verify that selected motor (torque) and linear guides can support workload.
  • Check the motor load torque.
    • Conditional values:
      Pulley dia. D = 0.048 mm,
      Linear guide coefficient of friction μ = 0.3, efficiency ƞ = 0.9,
      table weight MT = 1.5 kg, elevator unit weight MS = 3.5 kg,
      motor torque : TM = 0.64 Nm, guide allowable moment: MC = 98 Nm
    • Load torque T = F x D/2 x ƞ
      Thus, T = μ x (MT+MS) x g x D/2 x ƞ = 0.3 x 5 x 9.8 x 0.048/2 x 0.9= 0.32 Nm
      T<TM (Motor torque TM =0.64 Nm)
      Selected motor can handle application workload
  • Checking the guide load moment
    • Distance from the guide to the elevator unit L = 0.09 m
      Guide load moment: M = L x (MT+MS) x g = 0.09 x 5 x 9.8 = 4.41 N・m < 98 N・m = Guide allowable moment: MC
      ⇒No problem

Other Design Consideration

  • Belt allows for longer stroke and lower design cost.
