Technical calculations

■Life of Linear Bushing
When the linear system is loaded in linear reciprocating motion, scaly damages called flaking appear due to material fatigue as the repeated stress is applied on the rolling elements and the rolling contact surfaces constantly. Total travel distance until the first flaking occurs is called the life of linear system.
Rated life can be obtained from the Basic Dynamic Load Rating and the actual load applied on the linear bushings, as shown below.
  • L: Rated life (km)
  • fH: Hardness Factor (see Fig.1)
  • fT: Temperature Factor (see Fig.2)
  • fC: Contact Factor (See Table-3.)
  • fW: Load Factor (See Table-4.)
  • C: Basic dynamic load rating (N)
  • P: Applicable load (N)
Hardness factor (fH)

Fig.1. Hardness Factor

For liner system applications, sufficient hardness is required for ball contact shafts. Inappropriate hardness causes less allowable load, resulting in shorter life.

Temperature Factor (fT)

Fig.2. Temperature Factor

When the temperature of linear system exceeds 100°C, the hardness of the system and shafts will be reduced and the allowable loads will also be reduced compared to being used at room temperature, resulting in a shorter life.

Contact Factor (fC)

More than two linear systems are used for one shaft in general. In this case, the load applied to each linear system varies depending on machining precision and is not uniformly distributed. As a result, allowable load per linear system changes depending on the number of linear systems used on one shaft.

Table-3. Contact Factor

Number of bearings installed on one shaft. Contact Factor fC
1 1
2 0.81
3 0.72
4 0.66
5 0.61
Load Factor (fW)

To calculate load applied to the linear system, in addition to object weight, it requires inertia force attributed to motion velocity or moment loads. Further, it is necessary to accurately determine the temporal change of each. 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. Therefore, use the table below in order to simplify the life calculations.

Table-2. Load Factor

Conditions 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
1.5~2.0
With shocks / vibrations,
high speed: 60 m/min. or more
2.0~3.5
Life in hours can be obtained by calculating the travel distance per hour. When the stroke length and the number of strokes are constant, it can be calculated using the formula below.
  • Lh: Life (Hr)
  • L: Rated Life (km)
  • Ls: Stroke Length (m)
  • n1: Number of cycles per minute (cpm)

IDEA NOTE Chucking mechanism that converts cylinder thrust to spring force

As the cylinder strokes, the spring attached to the chuck unit is compressed and the workpiece is chucked by the spring force.
