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 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.In addition, the factors as operating temperature also significantly affect 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 Linear 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 according to the temperature factors.
* 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 2 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 rated life with Contact Factors on Table - 1.

Load Factor (fW).

Table-2. Load factor.

Conditions of Use fw
No shocks/vibrations, low speed: 15m/min. or less 1.0-1.5
No significant shocks/vibrations, medium speed: 60m/min. or less 1.5-20
With shocks/vibrations, high speed: 60m/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 load is applied to the a block, convert 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.

IDEA NOTE Workpiece setting repeatability

Mechanism in which a workpiece is positioned by a locating pin and retained by a toggle clamp.

IDEA NOTE  Improvement of workpiece setting workability

As the work piece inspecting position can be moved using the linear guide, it is possible to perform inspection in multiple positions.

IDEA NOTE The linear guide rail presser pin prevents the linear guide block from coming off.

As the work piece is positioned the linear guide could run off the track, to prevent this a rail presser pin also serves as a block retainer.
