Technical calculations
■Life of Flanged Linear Bushings
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 calculated with 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: Applied Load (N)
●Hardness Factor (fH)
For liner system applications, sufficient hardness is required for ball contact shafts. Inappropriate hardness causes less allowable load, resulting in shorter life.
Fig. 1. Hardness Factor
●Temperature Factor (fT)
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.
Fig. 2. Temperature Factor
●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.
| Conditions of Use | fw |
|---|---|
| No external shocks or vibrations and speed is low 15m/min or less | 1.0 ~ 1.5 |
| No significant shocks or vibration and med. speed 60m/min or less | 1.5 ~ 2.0 |
| External shocks and vibrations exist and the speed is high 60m/min or over | 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 Rotates workpieces with timing pulley
By mounting a work piece receiving plate just above the driven side of the pulley, and held with a double rowed angular contact bearing, the work piece weight against the motor and accuracy are improved.

- Total inertia of rotating part: J = 6083kg･mm² = 6083 x 10-6kg･m²
- Rotation start time: 0.1sec → Rotation start angular acceleration: dω/dt = 3.14 / 0.1 = 31.4rad/sec²
- Required torque of rotating part: Tr = dω/dt x J = 31.4 x 6083 x 10-6 = 0.191N･m
- Belt overload coefficient Ks = 1.6 (catalog value), Required torque of driving side: 0.191 x 1.6 = 0.306N･m
