■Life of Flanged Linear Bushings
When the linear system is in motion with applied loads, the rolling surfaces and races are subject to repeated stress. This stress can cause scale-like flaking due to material fatigue. The total run distance until the flaking appears is the "Life" of the 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.
Hardness factor (fH)
For linear systems, the shaft, that the balls contact, must have sufficient hardness. If the shaft does not have sufficient hardness, the load rating decreases and the life will reduced.
Fig. 1. Hardness Factor
Temperature factor (fT)
When the temperature of the linear systems exceeds 100°C, the hardness will decrease and as a result, the allowable loads and life will be reduced.
Fig.-2. Temperature factor
Contact factor (fC)
In general, it is common to use two or more linear bushings on one linear shafts. In these cases, the load on each bushing will vary depending on the machining precision and will not have equally distributed loads. As a result, the allowable load per bushing will vary depending on the number of bushings used on 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 bushings, in addition to the object weight, the inertia force attributed to the motion velocity, moment loads and the variations of each over time must be obtained. However, for reciprocating motion applications, it is difficult to obtain accurate calculation due to the effects of vibrations and shocks. Therefor, use Table2 to simplify the life calculations.
Conditions of Use | fw |
---|---|
No shocks / vibrations, ow 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. Then the stroke length and stroke cycles are fixed, use the equation below.
Slide guides are not required because the rod-less cylinder has guides.
You can reduce the travel distance by utilizing rod-less cylinders.
There are built-in bearings at the constraint fulcrum and rotational center.
